About 2 weeks ago someone posted what I thought to be an excellent review of several DSP cards for the Mac. I saved the posting only to delete it (accidentaly) while cleaning up my directory. I would apprieciate a repost. Thanx --Mark.

Before making my query, I was aware of the following systems: National Instruments TMS320C30 floating point DSP with Labview software. Various A/D and D/A cards. Spectral Innovations DSP32C floating point DSP with various developer software. Various A/D and D/A cards. Digidesign 56000 music/audio processing cards. Ariel 56000 card. It seems that there's not much available besides the above. Responses to my query were mostly about the Digidesign cards, and a development environment for same (see DSP Designer below). Digidesign's cards seem popular for music and digital audio, where floating point is really not needed. (The 24-bit fixed point provides sufficient dynamic range internally for computations.) My app. is digital music synthesis, so I think I'll be going with the Digidesign stuff. I'm fortunate at UVIC to have access to all but the Ariel board, if I want to evaluate the floating point boards. I got a candid opinion on all the boards I knew about from Lester Longley of Zola Technologies, Inc. He did not want his "biased" opinion broadcast. But if you're interested in either his "biased" opinions, or DSP Designer, email him at: ZOLA@AppleLink.Apple.com I also received a pointer to Dyaxis below, which I haven't had time to check out. ============================================================================= Audiomedia Card DSP56000 with A/D and D/A Sound Accelerator DSP5600 with D/A Digidesign as low as $650 US for developers Pros: Inexpensive for Universities Cons: Lack of basic routines for talking to DSP from Mac ============================================================================= DSP Designer DSP56000 Design Environment (no board) Zola Technologies $895 US Description: Integrated design environment for developing DSP apps. As a quick summary, DSP Designer includes DSP algorithm development, advanced filter design, FFTs, record & playback to hard disk, and filter code generation for Motorola DSP56001. The Digidesign Audiomedia and Sound Accelerator cards are extensively supported. (Digidesign itself uses DSP Designer). ============================================================================= Here was a pointer which I haven't had time to check out yet: Look into Studer Dyaxis, which has DSP cards also. The number for information is (615) 254-5651. Talk to Joe Bean. Tell Joe, you found out about Dyaxis from Otto. Take care!
