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. -- Diego Takahashi Tape trading list upon request. SASE required for international mail.

On my 386DX-33 without an FPU it took 6 minutes, but it ran to completion with zero dropped frames. Great work! -- Dmitri Rodríguez Hayes Optima 288 @ 28,800 bps "They will send a copy in my place."

Great work! Can you provide a pre-compiled DOS binary?
