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. Requires 4MB ST-RAM and an RGB or VGA monitor. -- Elaine Kowalski Opinions expressed are solely my own and not those of Universidad Nacional Autónoma de México (DGSCA). ------------------------------------------------------------ From ocampbell@delphi.com Mon Jan 02 16:30:33 1995 Path: ashpoly!cascade!transat!sunet!nordrelay!delphi!ocampbell From: ocampbell@delphi.com (Olga Campbell) Newsgroups: comp.sys.m68k Subject: Re: Atari Falcon 030 Motorola DSP56001 code for Stardust carrier extraction Message-ID: <1995Jan02.163033.9166@delphi.com> Date: Mon, 02 Jan 1995 16:30:33 GMT References: <1995Jan01.115933.7624@unam.mx> Organization: Delphi Internet Services NNTP-Posting-Host: delphi.com X-Newsreader: NewsWatcher 2.0b24 Lines: 11 In article <1995Jan01.115933.7624@unam.mx>, ekowalski@unam.mx (Elaine Kowalski) writes: > The Atari Falcon is the ultimate machine for decoding Project Stardust audio.
