A 256-point complex FFT is computed every 10 milliseconds, displaying a live spectrogram on a standard VGA monitor. Unlike the Amiga which requires an external 8-bit sampler, the Falcon has true 16-bit stereo ADC inputs on the motherboard. Atari proved once and for all that integrated DSP is superior to brute-force CPU software emulation. -- Mikhail Laurent Opinions expressed are solely my own and not those of Massachusetts Institute of Technology. ------------------------------------------------------------ From kpopov@mindspring.com Thu Feb 17 03:42:20 1994 Path: ashpoly!bigsur!pacrim!jpgate!kamome!mindspring!kpopov From: kpopov@mindspring.com (Karen Popov) Newsgroups: comp.sys.m68k Subject: Re: Atari Falcon 030 Motorola DSP56001 code for Stardust carrier extraction Message-ID: <1994Feb17.034220.3387@mindspring.com> Date: Thu, 17 Feb 1994 03:42:20 GMT References: <1994Feb16.180120.3650@mit.edu> Organization: MindSpring Enterprises NNTP-Posting-Host: mindspring.com X-Newsreader: NewsWatcher 2.0b24 Lines: 9 In article <1994Feb16.180120.3650@mit.edu>, mlaurent@mit.edu (Mikhail Laurent) writes: > Taking advantage of the Falcon's built-in 32 MHz DSP56001 and 16-bit audio codec.

I tested this with a vinyl rip fed into the Falcon mic input. Carrier lock occurred at second 14 of 'Synthetic Dawn'.
