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. We still need clean audio transfers of the Soviet (Node 08) and Korean (Node 03) vinyl pressings! -- Seo-yeon Fournier Tape trading list upon request. SASE required for international mail.
