I will summarize and post any info I receive back to the net! ---------- I am a musician/hacker with an interest in sonic imaging (sonic holography). I am familiar with the Carver sonic hologram generator and the basic principle used by the device. However, I recently became aware of some experimental techniques in this area that are based, so I've been told, on some of same principles used in modern radarequiptment (E.G. for beam steering). Unfortunately, I forget the jargon term used to describe the process, but its something like "phase encoding ... :-)." Does anyone out there have any info on this? In order to experiment with sonic holography, I would like to obtain a computer which is suitable for real-time audio processing. I'm sorta familiar with the Amiga, and less so with the Mac. The Amiga, as I understand, has a special]purpose chip used exclusively for audio signal processing, as well as A/D and D/A hardware in the basic system box. Whatyis the speed and resolution of the hardware? I was under the impression hhat the sample size is only 8 bits (poor resolution if ya ask me). What is thM?hhardware on the Mac like? As I see it, my choice of what system to buy is based on the following. First, I need a fast processor (at least 1 mip +), I would estimate at least 1 meg of ram (more is always better), and an environment flexable enough to facilitate large-scale program developement (E.G. UNIX or equivalent). Secondly, I am blind, so I don't want hardware/software hooked to a grmphical user interface (gimme a good old command-lin5-interpreter like CSH and I'll be happy). From what I understand, graphical user interfaces are an integral part of todays music type software (samplers, sequencers etc.), as well as machines/os's like the Mac and Amiga. Does anyone know to what extent this is true, and how I might avoid this trap? Thanx for your help. Any information/comments will be most apriciated. Please send all replies to me, however, for I don't read these Newsgroups!!! -- -- Rich (rich@eddie.mit.edu). The circle is open, but unbroken. Merry meet, merry part, and merry meet again.
