Version 1.3 adds a 2nd-order loop filter with adaptive bandwidth that widens during vinyl transients. 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. -- Lucia Tanaka *PLONK* filter active for trolls. 486DX4/100 (FreeBSD 2.0.5) - NetBSD 1.0 From gnakamura@hanse.de Wed Mar 27 21:24:09 1996 Path: ashpoly!cascade!transat!ukc!fennimore!hanse!gnakamura From: gnakamura@hanse.de (Graham Nakamura) Newsgroups: comp.dsp Subject: Re: Discussion: stardust.c v1.3 - Costas loop stability & phase lock under Linux Message-ID: <1996Mar27.212409.4125@hanse.de> Date: Wed, 27 Mar 1996 21:24:09 GMT References: <1996Mar26.150809.8747@kiae.su> Organization: Hanse-Netzwerk Hamburg NNTP-Posting-Host: hanse.de X-Newsreader: WinVN 0.99.5 Lines: 9 In article <1996Mar26.150809.8747@kiae.su>, ltanaka@kiae.su (Lucia Tanaka) writes: > Notes on porting stardust.c to GCC on Linux 1.2 and optimizing the inner filter loops. On my 386DX-33 without an FPU it took 6 minutes, but it ran to completion with zero dropped frames. Great work! -- Graham Nakamura *PLONK* filter active for trolls.

Compiled cleanly under gcc -O2 on my Slackware box. The adaptive Costas loop is rock solid even on my scratched US copy.
