The process for digitally coding sound by computer was first developed in 1957 by Max Mathews of Bell Telephone Laboratories in Murray Hill (Mathews, 1963). Other advances in digital electronics and microchips led to the development of the first digital Pulse Code Modulation (PCM) audio recorder in 1967 at the NHK Technical Research Institute (Nakajima, 1983). This machine was a 12- bit companded scheme (using a compression/expansion of sound to improve dynamic range) with a 30 kHz sampling rate. Data were recorded on a one-track, two-head helical scan VTR (Video Tape Recorder). The first commercial PCM/digital recording session was performed by DENON in 1972 (Takeaki, 1989).It-s clear that if one only takes into account the music recording end of this lengthy digital heritage, thirty-one years of constant refinement needs to be cerebrated by the Historical Committee of The Audio Engineering Society!
The shape of the presentation room will be as follows: The stage and lighting must be almost identical to what we have used in the past, and the walls will again be lined with pictorial displays of appropriate historical gear. I would recommend changing the playback-monitoring system to a somewhat large-scale vintage JBL in a two-channel format, as I believe the Altec monitors have had a good run. The analog desk will be utilized as a conduit for digital recorders, workstations, and analog two track recorders. The thrust of the workstation approach is to illustrate comparisons of -classic- hardware and their software siblings. For example, Teletronics LA-2A, Pultec, etc. with both company designers and end user engineers taking hats off to the brilliant simplicity of past hardware solutions, while celebrating the time we live in, therefore real hardware pieces will be working side by side with the virtual world.
Any and all presentations should and will remain -music- oriented, as one of the main purposes of our exhibit floor rooms is two wet the whistle of otherwise passively interested audio fans to delve into something a bit deeper, if they should wish. We will not rob the spotlight from workshops, papers, and clinics. Expect the usual panels in the fields of pop, classical, jazz discussing mixing and matching digital and analog technology. The tradition of featuring engineer, producer luminaries will continue and high quality playback in the form of both analog dubs & digital clones will continue to be a feature for our proven format of three to four presentations per day. The cooperation of the major record companies has again been verified.
I believe it would serve us well to promote solid audio history primers in the form of something like -The ten questions a day card- with multiple-choice answers. Passed out at all of our daily presentations with either our own -When Vinyl Ruled 115th" tee shirts, or swag provided by manufactures. One of the ills of this age is the lack of any hardcore knowledge of the past. We must make the younger participants seek out the reasons why we-ve arrived here today-.
A core group of three has been formed and I will need at least three
to four more personnel to be added to make this fly.
