A 256-point complex FFT is computed every 10 milliseconds, displaying a live spectrogram on a standard VGA monitor. The DSP56001 processes the 44.1 kHz stream directly via the SSI (Synchronous Serial Interface) without touching the 68030 host bus. Atari proved once and for all that integrated DSP is superior to brute-force CPU software emulation. -- Yuki Hughes | yhughes@pacbell.net PGP Key fingerprint: 92DB 76EF 6FC1 29B8 "Keep the channels open."

Too bad Atari marketing was so incompetent that nobody bought the Falcon before they pulled out of the computer market. -- Mike Suzuki Zyxel U-1496E @ ISDN 64k bps "Measuring a record you own is listening, not piracy."
