(ABC audited) 1N V A United Newspapers publlcsdon Logical alternative Apart from a small number of die -hards, we are currently busy building an increasingly `digital' present on the ashes of our analogue past. Where once ever -improving analogue recording equipment looked indefinitely able to provide for all our needs, digital technology has offered us an irresistible alternative-one free from many of the intrinsic limitations of analogue. Currently, we are all too engrossed in the advantages of digital to look at its intrinsic limitations. Or are we? There is an alternative to the accepted logical foundation of digital technology and it is gaining ground alarmingly quickly. While the West in general -and Western Europe in particular -has ignored it, the Far East has begun to embrace it and already incorporated it into hi -tech systems ranging from rice cookers to helicopters. This alternative is grounded in `fuzzy logic' as opposed to our Aristotelian logic. It is born of a `fuzzy' school of scientific and mathematical thought where the `black and white' logic of conventional mathematics have been replaced by a `grey' logic -where zeros and ones give way to the values between, where bits defer to fits (Fuzzy unITs) and MIPS to FLIPS (fuzzy logical inferences per second). Fuzzy logic, argue its protagonists, give us back the real world vagaries missing from present mathematical systems and in doing so, give us a convention that more closely represents the day -to-day mechanisms of life. Illustrating the practical shortcomings of Aristotelian mathematics is easy-take a look at quantisation error, for example. Offering an attractive alternative to it is less so. But only in mathematics are matters perfectly precise, everything we, and our equipment, set out to achieve involves degrees of a situation rather than all -or- nothing situations. By adopting imprecise methods of assessing a situation and directing resources, fuzzy logic addresses the real world on common ground. Fuzzy logic is claimed to go so far as to allow machines to `reason' in a way analogous to the human brain (significantly, it is now an important part of AI research in the form of neural nets). Certainly, fuzzy systems demonstrably offer smoother control and processing than traditional digital systems. It is no surprise that fuzzy logic (or vague logic, as it was originally called) and fuzzy maths are having a hard time in academia; after all, they challenge the very heart of logical thinking-in the West. In the Far East, however, the vagaries of fuzzy logic strike a harmonious chord with many traditional philosophies, a fact which appears to have further hindered Western acceptance. A number of Eastern nations have, however, taken to fuzzy thinking, and a significant part of their hi-tech industries now makes use of it. An indication of the Japanese commitment to fuzzy technology can be judged to some extent by the fact that they now operate two research centres dedicated to it -the Laboratory for International Fuzzy Engineering Research (LIFE) in Yokohama and the Fuzzy Logic Systems Institute (FLSI) near Tokyo. Both were established with the assistance of MITI (the Ministry of International Trade and Industry). The companies represented by the Board of Directors of LIFE include high-ranking executives from the likes of Matsushita, Toshiba and Hitachi; its inaugural membership stood at around 50 companies including the likes of Sony, KAO and Mitsubishi. In the Far East, fuzzy logic has already made a positive contribution to a wide variety of products -some industrially pitched, others intended for the domestic market. A palmtop computer from Sony, for example, and video camcorders from Panasonic, Canon and Sanyo join an assembly -line scheduling from Omron give some idea of the scope and scale of fuzzy applications. Make no mistake: the Far East is serious about fuzz. Fuzzy thinking is slowly being accepted in to US too. And unless the whole concept of scientific fuzz is soon proven to be invalid, we can expect to see it making its presence felt in audio and video equipment imminently.

The RIAA indicates approximately 2 million counterfeit cassettes were seized in 1993 -down from 2.5 million in 1992. The association have explained the decrease in street sales of counterfeit cassettes is directly linked to a decrease in the number of manufacturers, distributors, street vendors and other individuals producing and selling counterfeit cassettes. This fact, they say, is due to the maturation of a number of RIAA programmes introduced over the last few years, targeted at illegal street vendors as well as manufacturers and distributors.

I noted the resulting time position for each one in order to make up a PQ listing for the 1630 and sent the DAT to one of London's most reputable copying houses-one which had specifically been recommended as having considerable experience with CD-R and the SmartBox. It therefore came as a surprise to find the IDs had been effectively remastered on hard disk (with PQ worked out by listening to my DAT) for the CD. It seemed I was expecting rather more from the system than it was designed to deliver. Precise transfer of DAT IDs -so that they end up on the CD in exactly the same place relative to the music -is fraught with unexpected difficulties. In the first place, a DAT with precisely positioned IDs is a rarity in itself. Few machines allow the kind of frame -accurate placement that the D20 provides; even those that have a rehearse function often work in increments of a few frames. Auto identing is just about the only way most people have of placing them hard on the start of a track-the resulting position varying according to the nature of the initial sound and the way in which the individual DAT machine operates. Then there is the time taken for an interface box to recognise the ID in the datastream. Ideally this is predictable, but if an error should occur on the tape at the critical moment, it may take longer for the ID to be distinguished from the audio. Finally, there is the time taken for the CD -R transport itself to write its ID, which apparently varies from machine to machine. The only way to allow for this with confidence would be to find out each model's inherent delay by trial and error, and hope it does not change next time the software is upgraded. All these problems can be overcome given the will. The first is not really a problem; IDs can be written onto a DAT in precise positions. The second is a small consideration, and probably makes little practical difference. This leaves the last, with the time -consuming and CD-R blank-wasting task of tinkering with delay times until the right offset is found for the particular combination of equipment, and this is the bit nobody seems to have done. It seems judging from from the various people I have spoken to -that nobody has ever asked for this kind of precision in such a transfer. I ought to say at this point that none of this is intended as undue criticism of any of the systems currently available. They clearly meet a need, carry out their intended tasks well, and are already pushing the technology further than it was originally designed to go. It seems to me, however, that it could be pushed even further, and that some work still needs to be done if its full potential is to be realised. Am I asking too much? Am I asking for something that nobody else wants? If there is anybody out there who would find the kind of facility I am talking about as useful as I perceive it to be, then take this as a call to arms. If not then please beware: DAT-to -CD -R transfer is not yet an exact science. Dave Foister The last couple of years have seen much discussion over `consumer' technology in professional service. One medium not yet caught up in the debate is CD -R, but this too was originally a domestic format. I was reminded of CD -R's domestic origins, however, by a recent experience, which I offer here for open comment. I had finished mastering a CD project -apart from the PQing, which was more complex than usual. The content was a live recording of the Guildhall School of Music and Drama's production of Curlew River, a piece by Benjamin Britten, which runs for 73 minutes without any clear movement breaks in which it is not at all obvious where the `tracks' should appear. Immediately the question becomes an artistic rather than a straightforward technical one. Having established points in the score where an ID would make some musical sense, it still remains to ensure that, where possible, the CD can be started with a little initial ambience. One possible set of track positions suggested itself, and I decided to have a CD -R made with these in place. It struck me that the simplest way to do this would be to make use of one of the systems which can convert DAT Start IDs to CD track numbers during transfer. These systems exploit the fact that Start ID data appears in the SPDIF datastream (not in AES -EBU) and can be used to trigger the CD-R machine to write a track ID. A problem with early equipment was the fact that it takes a finite time for the unit to recognise the Start ID and to carry out the conversion, often resulting in the CD index appearing late. This is further compounded by the fact that many source DATs are idented using an automatic ID facility, which writes a Start ID when audio rises above a certain threshold after a period of silence; this, usually places the ID late'. There are currently two units available to carry out ID transfer (with other manipulation of the data): Audio Design's SmartBox 2 and HHB's CDR Indexer. Both manufacturers are aware of the aforementioned problems, and both have attempted to address them by delaying the audio data. Both incorporate variable delays, the HHB defaulting to a maximum of 185ms and the SmartBox using a `zero' reference value of around 400ms which can be varied upwards or downwards in increments of about 70ms (dependent on sampling rates) to a maximum of almost 1.5s. It seemed reasonable to assume that if the DAT IDs were in the right places, the interface's delay could be set so that the CD -R machine would replicate those ID positions on the CD. With this in mind, I took a DAT clone of the Sony 1630 master where the relationship between the DAT A-Time and the 1630's time code was known to within a frame. I placed Start IDs on the DAT using the ID Rehearsal function on the Fostex Thanks to: Tim Channon, Designer of the SmartBox; Phil Beville D20.

From this point on, there have been continual developments which have marked recognisable steps forward in the quest for improved live sound. The first major revolution was the Altec Voice of the Theatre system which was employed into the 1960s in various forms, where large multiples of units were required for the emerging requirement of high -power requirements for rock concerts. Good as these systems often were, they were difficult and time-consuming to set up, as well as returns'. In order to achieve correct coupling characteristics for multiple enclosures, the cabinets are often presented in trapezoidal form, and should ideally incorporate the angles defined by the horizontal directivity characteristics of the system. Attempting to make these considerations can often give rise to ergonomic and manufacturing problems and, consequently, is not always a feasible option. Where modern systems (in the right hands) are capable of excellent results, there is a growing feeling among engineers that the control end of sound reinforcement system has far outstripped available speaker systems in terms of performance -and that it is once again time to being physically bulky and difficult to move forward. move around. In the search for a The challenge has been taken up better system, the research work by L'Acoustics in France, led by done by Meyer Sound Labs' John acoustician Dr Christian Heil.

Other shortcomings include namely: a horizontal coverage angle limitations on the maximum acoustic of 90° ( -6dB down points) with a power output in any one direction, vertical angle of 5° per enclosure. It coupled with the law of diminishing has been found that the vertical coverage requirements are normally found between 10 °-40 °. The vertical coverage corresponds to the diffraction of a flat isophasis radiating ribbon, the angle of which varies according to frequency. In the case of a single enclosure, this angle is 5° at 12kHz and correspondingly wider for lower frequencies. This results in a major improvement in stacked arrays: the coupling of V-DOSC enclosures is Cylindrical propagation correct for all angles between 0 °-5° and is defined by the high-frequency content required. At 0° the coupling is claimed to be perfect at any frequency, at 5° the upper limit is around 12kHz. In the case of enclosures being stacked at 0° (one on top of the other!), the HF limit will be that of the HF driver, with the vertical coverage being determined by the height of the stack. Should a wider horizontal coverage being required, separate systems should be used and Spherical propagation spaced at a sufficient distance to 14 Studio Sound, March 1994 avoid interference problems. The coupling characteristics of V-DOSC can be summarised as follows: a plane and even array of 0 identical sound sources is equivalent to a single sound source having the same shape, providing that the wavelength is larger than the step of the array' (Step 110dB, electromechanical very few drivers can produce such continuous sine limitations of the drive wave levels, so comparison is not really relevant. unit, including thermal Furthermore, certain audiological reasons reduce power compression the relevance of very high -level measurements in a effects, suspension studio environment.

Amplitude and phase responses that the audible similarity groupings from the listening tests could be described in terms of the reflection patterns shown in the power cepstra. The various reflections and resonances produced in the cone of a direct -radiating loudspeaker can give rise to irregularities in the frequency response function that are similar to those due to mouth reflections in short (sub 350mm) horns. This explained the anomalous behaviour of the `long' Fostex wooden horn in the listening tests. As previously mentioned, the horn was strongly identified as sounding similar to the direct radiating cone, archetype B, but the cepstral analysis showed that the true `horn' was the 150mm throat section only, with the 140° horizontal wooden flare acting 63 2 2 o 11111111 lmr.tr ...tllluilllllLr...t.. 0 7: As `5' 2 IIIIILIIItIIrrt.nt..dllnlll.IH. o 4 Time (ms) 6 o o 4 2 6 0 Tizne (ms) but with the lips sawn off axisymmetric horn 8: AX2 111111111 9: 1IIIlllhl.11ll.iltl1lu 2 4 Time (ms) 6 Yamaha horn with EK175 driver Fig.2.4: Power cepstra of sample loudspeakers DYNAMIC MODULES In case you jr-- EXP/GATE 4 haven't already met...

The unevenness in the throat impedance was largely due to the abrupt, horn-to-lip termination at about 150mm from the driver diaphragm. The horn was consequently reclassified as a 150mm horn with 290mm lips (the shortest horn of all tested), explaining the similarity between this horn and the direct radiators. It should be remembered that there is no absolute dividing line between horns and direct radiators, as a direct radiator can be considered as a 180° conical horn of zero length. The longer horns, even those with relatively good mouth termination (which is usually easier to achieve in a long horn,) are identified as horns by the temporal spacing of the reflections. Even when the reflections are significantly lower in level than those of the short horns, the greater separation in time of these reflections are recognised by the ear as a pattern which we know as a horn-like sound. The two horns which were not identified in the listening tests as sounding like archetypes B or C, were both shown by cepstral analysis to exhibit minimal mouth reflections. One of these horns was long, and one was short. The long horn, though showing some similarity to C, did not have a particularly strong resemblance, and was considered on some sounds to be similar to archetype A, the Electrostatic. The short horn showed a considerable sonic resemblance to archetype D, the Tannoy dual concentric: both the Tannoy and the Quad Electrostatic have their roots in 1950s design, yet are still in daily use in `quality control' suites. Furthermore, both of these units had historic `difficulties' in the low and high-frequency ends of their performance, but both had a clear midrange, suiting them to quality control applications. Apart from reasons of inadequate (woolly) bass, and limitations on maximum sound pressure level, these loudspeakers also lost favour as studio monitors as a result of not sounding representative of other loudspeakers in general. From the cepstral analysis the reason for this is clear, but it poses an interesting philosophical point: should a monitor loudspeaker be rejected because it does not possess the midrange problems inherent in most other production loudspeakers? While the Electrostatic, archetype A, was deemed similar to the sample loudspeakers on a relatively small number of occasions, it was frequently noted that one of the nine test signals (a recording of a waterfall, band -limited 1k -6kHz on playback) sounded more `wet' on A than on any other loudspeaker; a testament to its reality.

Other than certain materials having specific problems due to bad design or construction, no evidence was found to indicate that any well-damped, solid material could not be used in the manufacture of horns. Obviously, certain materials lend themselves more readily to the manufacture of different shapes, and it could be that some materials have had sonic characteristics attached to them because they are only found on certain generic designs. Wave shapes Investigations into the actual wavefronts leaving the different horns, showed that the axisymmetric designs generated waves which resembled flattened spherical caps, midway between a true spherical expanding wave and a plane wave leaving the mouth. The waves leaving rectangular horns were of the form of spherical expanding waves which struck the walls of the horn at 90°. Early in the tests, `bubble -blowing' experiments were performed -wire loops were bent into the mouth shapes of the horns to be tested, and it was noted that only circular, or near-circular mouths would produce complete bubbles; rectangular shapes causing the bubbles to tear themselves apart before they could leave the wire. It was also noticed that rectangular horn designs would produce disturbed responses when listening to them or measuring them from a position 90° to any discontinuity. Such discontinuities include waveguide plates, the top- bottom to sidewall junctions, and any other departures from a smooth surface. The mouth shape and any internal discontinuities tend to produce reflections from the mouth or strange aberrations in the off-axis responses. All of these things were strong pointers in the direction of the concept of axial symmetry being the only viable option for the highest quality reproduction.

In the above tests, the axisymmetric AX2 horn was driven by an Emilar EK175 compression driver. In the cepstrum plots shown in Fig.2.4 the combination is sample 8, and a small reflection can be seen at a distance of about 50mm from the diaphragm. Investigation showed this to be due to the slightly differing flare rates of the driver throat and the throat of the horn. When mated with the TAD TD2001 compression driver, the flares match exactly and the reflection disappears. The power response of the TAD is also such that its falling high-frequency response is closely matched by the gradually narrowing directivity of the AX2 horn, producing a smooth on -axis pressure amplitude response, together with an off-axis response where the fall -off of high frequencies takes place in a smoothly controlled manner. These responses are shown in Fig.3. Monitor systems using the TD2001 -AX2 combination are now in commercial use, particularly in control rooms of a very nonreflective nature where the on -axis response is highly important. These monitor systems, especially in inexperienced hands, do suffer from some of the criticisms formerly aimed at the Quad Electrostatics and Tannoys, in that they are not necessarily representative of other loudspeakers, but equally, many experienced engineers praise their ability to pinpoint fine detail.

In many ways, the AX2 could be defining the limits of midrange horn design. The axisymmetric shape (Fig.4) seems to be the only one which can produce an output free of the irregularities of response caused by pillars, plates, other obstructions or surface junctions. Horns much more than 300mm in length begin to produce `horn -like' sounds unless the mouth termination is close to perfect. Given that the rate of flare dictates the throat cut-off frequency, and the mouth size controls the smoothness of the low- frequency termination to the room, then a horn with a low cut -off frequency, possessing a mouth which smoothly flares into the baffle, would be of such great length and mouth size that close coupling to the other drivers in the loudspeaker system could be almost impossible. The AX2 has a cut -off frequency of around 750Hz, but is so smooth in its response that it can be used through cut-off. This is the lowest cut -off frequency that can be achieved, consistent with a flare which smoothly blends into the baffle, originating from a 1 -inch throat in a diaphragm -to-mouth distance (with TD2001) not exceeding 300mm. However, a high -efficiency horn system, usable from below 1kHz to over 20kHz, with a mouth diameter of 121/2 inches, capable of producing very high fidelity and a maximum output of 125dB at 1 metre is certainly a useful tool. What is more, it definitely is not `horn-like' in its sound. Clearly, when the many variables are fully understood and appreciated, horn systems can be produced which do not possess any typically horn -like vices. Attention to detail is a prerequisite, as is a comprehensive knowledge of the caveats. Two further aspects of horn design are called into question as a result of this research, both requiring further investigation. Firstly, given the extreme sensitivity to small disturbances in the throat region, can the Tannoy concept of having an actual gap in the horn, (the voice -coil gap of the bass cone) ever be expected to produce optimal results? More particularly, when that gap is modulated by high levels of bass driver movement, can a variable length, variable flare, gapped throat ever be expected to produce optimal results? Secondly, the results show that any abrupt flare -rate changes within the horn, can, do, and will cause reflections which will superimpose themselves on the transfer function. As the whole concept of constant -directivity horns relies upon flare-rate changes of no subtle nature, then can the best results ever be achieved from constant-directivity horns ?10 Fig.5 shows the measured throat impedance plot of the AX2, & PHASE CORRELATION LEVEL AT GLeNCF To improve audio metering - focus your attention on both key parameters of audio signals: PEAK LEVEL and PHASE CORRELATION 1119 DIN Version mounted into case 1120 1134 British Scale Version (Nordic Scale Version: 1139) Built -in Phase Correlation Meter Peak Programme Meter for analog + digital audio tl0 lue Memo IIIInIBDINDnl1111pp8pgpt .zodó 1 I dB -20 -50-40 -30 1 IIIIIIDnnpllllllilllllllll Dlll8llll:IIIIpIl8eip01p0111g IIIIIIIII8p8ppnp800 -10 1 I I 1 1 1 1 1 1 1 1 1 1 0 -5 1 RTW 1 5 11111111111111 Reset 1 1D RTW Peakmeter & Correlator RTW RADIO- TECHNISCHE WERKSTAT-EN GMBH Telephone (221) 7 09 13 -33 Telefax (221) 7 09 13 -32 D -5000 Köln 71 P.O.

Director at: 3A 6 ELECTRONICS 24 Southgate Road, London NI Fax: 071 -241 3644 3J) t the Annual General Meeting of the Performing Rights Society (PRS) in September, John Timperley asked a question that seemed innocent enough at the time but only later revealed its full working within five years, probably far sooner. The PRS accept that copyright collection is too costly in the UK. Already royalty information is going into the MCPS computer, and from there being relayed electronically to the PRS. If the PRS had known a bit more about IT in the first place, they would surely have seen the need for an IT Director to pull the PROMS project together, warn of the risks and perhaps warn against even trying to replace the human element. Or the PRS could simply have talked to Brian Eno. Eno started out playing with flamboyant 1970s rock art -group Roxy Music, went on to earn himself an enviable reputation as the producer of records made by David Bowie, Talking Heads and U2, and makes his own `ambient' music as well. He spends his life working-in part -with computer-controlled synths, such that the pop music press dubbed him `Professor Eno'. Recently the University of Plymouth gave him an Honourary Degree. -so Eno is now A significance. `What qualities does new Chief Executive Ted McLean feel he brings to the post ?' Earlier PRS Chairman Wayne Bickerton had told the PRS members that McLean's appointment in April had, `...set us on the road to efficient and properly-tailored new information systems, and to management restructuring which will contribute to a decrease in administration costs.' McLean told Timperley: He had been responsible for the information technology function in a large company in the past.' Just a month later, the PRS sent out a letter to its members. `Mr Edward McLean has offered his resignation and it has been accepted by your General Council... Mr McLean was selected from several appropriate candidates who had been short- listed from a very large number of applicants... the appointment was made on the basis of the information given to the interview panel... certain information, which has recently come to light, was brought to the attention of the General Council and, after discussions, Mr McLean decided to resign.' For obvious reasons, the PRS are saying no more, other than to explain that Ted McLean had previously worked for movie distributor UIP. What the PRS will say, however, is that they have now created and filled a new position- Director of Information Systems-and the PRS are talking seriously with the MCPS about some kind of a tie -up or merger to cut administration costs. This would bring Britain into line with other European countries, like Germany and Holland, where work on the collection of royalties on musical performances (done in the UK by the PRS) and on collecting royalties on recordings (the MCPS) is handled by a single bureaucracy. It is the infamous PROMS episode that has concentrated the copyright collectors' minds. In 1988, the PRS decided to make revolutionary, rather than evolutionary, changes to the computer system which kept track of royalty collection and distribution. 74 Studio Sound, March 1994 a Doctor of Technology. Barry Fox Last night of the PROMS: the need for education on information technology The new system would be called the Performing Rights On -line Membership Service, or PROMS. The plan was to get rid of the ICL mainframe computer used by the PRS, and replace it with a database program run on a network of personal computers. The PRS earmarked £10m for the project, which inflation pushed to £12m. Hardware and software were bought and project managers appointed. Almost immediately things started to go seriously wrong. The PRS had grossly underestimated the difficulty of automating a system which relied so heavily on human beings helping the computer. As one insider astutely put it: The human beings had been the chips. They had been tying all the loose ends together, and it was impossible to create a single all-embracing electronic system'. In November 1992, the PRS froze all further development of PROMS. Ewen Fletcher was commissioned to produce a report which was only ever seen in full by the PRS Council. synopsis quite bluntly told the PRS that PROMS would never work -however much money was thrown at it. The report also recommended that the PRS create a new post, Director of Information Systems. The new Director is John Rathbone, who was working in the role as consultant before he got the permanent job. PROMS was a complete failure. The system never went on line. On Rathbone's advice, the PRS have now scrapped the idea of revolution and gone back to evolution of the ICL mainframe. In all, the PRS spent £11m of the budgeted £10m, but reckons that only (!) £8m of this was a complete write -off, because £3m was spent on hardware, software and training. Although the PRS and MCPS had been talking for years about a possible liaison, the watershed was the anger of PRS members who saw their royalties squandered on the PROMS debacle. The two industry bodies are now committed to joint A With the Professor's kind permission I quote from a letter he wrote to a friend after buying a new computer and struggling with the instruction manual. `Welcome to your new computer. We would like to thank you for agreeing to sacrifice the best years of your life trying to understand an under -evolved technology. If you have never used a computer before, then this is a really bad time to start. The first section of the manual explains how to use the section of the manual that explains how to use the rest of the manual. Before you read this section, please familiarise yourself with the following section which will make clear why the first section was important. When you have read the manual you will not be able to understand your computer, but you will be considerably older. `Setting up your modem: Where you will learn the difference between application folders, modem startup documents, SCSI disk mode and autoremounting. `If your modem will not work... `Please consult Troubleshooting... `Problem: Modem not working... `You have run out of memory, or acquired this product before its design phase was completed, or the salesperson who told you that the use of the modem was straightforward was a pathological liar.'
