Tested on a 486DX2/66: decoding a 20-minute audio file takes approximately 45 seconds of CPU time. Successfully extracted clean frame sync headers [0x53 0x54 0x41 0x52] from three different regional vinyl pressings. Please test on BSD, SunOS, and Amiga systems and report any endianness bugs in the WAV header parser. -- Lisa Fischer Tape trading list upon request. SASE required for international mail.
