QTelevision, to post production on the Fleetwood Mobile's footageof the Russian ballet in Leningrad. The two companiescomplement each other well, enabling each to offer acomprehensive service to their clients.Woolley first came across the Raindirk consoles in theFleetwood Mobile. He felt the Symphony offered extremely lownoise, economical price, good sound and fast availability, andhas had no regrets. In fact he is very pleased. "There areaspects of the desk which belie its price. There are hundreds offoldback and auxiliary sends, 90 line inputs to mix, 32 groups, abig patchbay, and there are two stereo buses which you can mixtogether."The most recent acquisition is an Adams Smith ÁV2600synchronisation system. The AV part of it offers computercontrol of the 2600 modular synchronisers, via a QWERTYkeypad attached to an IBM PC and screen."This means that you operate it much like a CMX videoediting system: for up to 10 machine edits, for slipping thingsaround, for previewing edits and all that sort of thing; it reallyis an expansion on systems like Q.Lock which I was, and stillam, a huge fan of."The Q.Lock's control surface is its strength and there aren'tmany synchronisers around that can compete with that. But Ihaven't found anything yet that this AV system can't do. It'sfantastic. It gives you a lot of the functionality of hard diskeditors without having to use hard disk media. One of the majorbenefits of the AMS AudioFile system is its capability to controledit decision lists. With AudioFile you find a portion of audioyou're talking about, define that with timecode numbers andpaste into where you want it to go in the programme. Themethods you go through with this AV system are really verysimilar to that -its `computer' style and the manipulation, of theedit list. The only exception is that the audio samples are heardon tapes."I don't deny any of the new functions that hard disk editingoffers -direct access to data, non realtime manipulations, minuteediting with no pre -roll and so on but I now feel that thesemanipulations should take place outside the control sessionrecorder and not replace it."At Trilion we operated AudioFile as the only multitrack in astudio and stored all the session audio in it, which seemed alogical approach. Now I feel that all the session audio should belaid up onto digital multitrack and sections that require harddisk editing should be transferred off -tape, manipulated, thenreturned to tape -all in the digital domain, of course."This approach sidesteps the need for massive amounts of harddisk memory since we only require to load short sections -say 30seconds."Because of this, I'm interested in the new samplers that offerhard disk storage and audio manipulation at a fraction of thecost of hard disk editors."I did a project recently sound dubbing Grimms fairy talesread by Rik Mayall. We recorded 12 episodes- approaching 24hours worth of material -on a single reel of tape. It was doneover a short period of time, constantly switching betweenprogrammes, so that where similar effects had to be placed ondifferent programmes we would rapidly switch between them.Trying to do all the production on hard disks would have putrestrictions on moving around having to load down and load upthis limited amount of disk storage in between takes. Therewere times where I would have liked to add in 2 seconds ofstudio noise from somewhere else to cover, or a consonant froma word in from somewhere else to cover an extraneous noisethatsort of thing- but now we're talking about inserting littlebits, not having a massive amount of memory."With the more musical instrument -like hard disk units youcan get any sound you like and then manipulate it. That tendsto be what our clients want; more to do with sound effects,taking effects from an effects CD and modifying them to suit."Woolley's main concern about hard disk systems is thereliability of the actual disks. As a pioneer he admits that hewas very quick to point out the advantages and brushdisadvantages under the carpet."In my experience disks have broken a number of times.There have been communication problems between the floppyand Winchester disks (floppies are used for manipulation,Winchesters for music storage). A lot of studios have boughtAudioFile and are very happy with it. I was probably expectinga bit too much of it."Aspects of hard disk remain invaluable; others a pain in theneck. There is the problem of limited storage, questionablereliability- whether you'll get the same thing twice, or threetimes or 10 times or 100 times. It does seem to me that youneed the audio juggling capabilities of hard disk in certainphases of your production, but after you've finished jugglingthem and you like where they are then I think you want a bitmore of a full stop after that and you say `you mustn't let meerase any of these commands I've put in'."That's what you can really do with tape. You can record itdown onto a track with all your edits in it and then leave italone and the next time you play it it is still there; and the nexttime and the next time; and it isn't going to move by half aframe; and the edits aren't going to move. You see there areproblems with hard disk caused by all these editing capabilitiesalways being available. It would be nice to stop thosecapabilities occasionally. Some combination between disks andtape will be the future. There is no question that there areadvantages in retrieval systems that are independent of timeand position."The aim is to do as many jobs as possible in the machineroom -anything involving simple copying between tapes on the16/35 mm playback. DASH ya in recorder, PCM1630 and twoU- matics plus sample rate converter. There are tielines fromhere to Doublevision's facilities- video, analogue and AES/EBUdigital. A number of jobs involve simultaneously running digitalsoundtracks played back from 1630 and copying those ontoeither 1 in analogue or digital (audio) video recorders. In thelatter case the audio will be taken down an AES/EBU line. Ifthe video recorder is an analogue audio machine it willobviously be taken down analogue tielines. Two Adams SmithZeta 3 synchronisers are employed to lock up between the 1 inmachine and the 1630 U- matic.The equipment room looks onto the mixing desk in the controroom75
