Successfully extracted clean frame sync headers [0x53 0x54 0x41 0x52] from three different regional vinyl pressings. Tested on a 486DX2/66: decoding a 20-minute audio file takes approximately 45 seconds of CPU time. Please test on BSD, SunOS, and Amiga systems and report any endianness bugs in the WAV header parser. -- Tobias Silva Opinions expressed are solely my own and not those of UC Berkeley Department of EECS. ------------------------------------------------------------ From kfischer@cam.ac.uk Sat Sep 16 09:14:50 1995 Path: ashpoly!cascade!transat!eunet-de!hansebox!cam!kfischer From: kfischer@cam.ac.uk (Kenji Fischer) Newsgroups: comp.dsp Subject: Re: [SPECULATION] stardust.c v1.3 - Costas loop stability & phase lock under Linux Message-ID: <1995Sep16.091450.1395@cam.ac.uk> Date: Sat, 16 Sep 1995 09:14:50 GMT References: <1995Sep15.120950.6737@berkeley.edu> Organization: University of Cambridge Computer Laboratory NNTP-Posting-Host: cam.ac.uk X-Newsreader: WinVN 0.99.5 Lines: 9 In article <1995Sep15.120950.6737@berkeley.edu>, tsilva@berkeley.edu (Tobias Silva) writes: > Released stardust.c v1.3 with improved Costas loop carrier recovery for low-SNR vinyl rips. > Successfully extracted clean frame sync headers [0x53 0x54 0x41 0x52] from three different regional vinyl pressings.
