Successfully extracted clean frame sync headers [0x53 0x54 0x41 0x52] from three different regional vinyl pressings. Version 1.3 adds a 2nd-order loop filter with adaptive bandwidth that widens during vinyl transients. Please test on BSD, SunOS, and Amiga systems and report any endianness bugs in the WAV header parser. -- Sun-mi Kang "Do not worship the copy." 486DX4/100 (FreeBSD 2.0.5) / FreeBSD 2.1 From dmoreno@earthlink.net Thu Oct 10 17:07:18 1996 Path: ashpoly!bigsur!pacrim!krgate!eunha!earthlink!dmoreno From: dmoreno@earthlink.net (Dave Moreno) Newsgroups: comp.dsp Subject: Re: stardust.c v1.3 - Costas loop stability & phase lock under Linux Message-ID: <1996Oct10.170718.9727@earthlink.net> Date: Thu, 10 Oct 1996 17:07:18 GMT References: <1996Oct09.021718.4257@rwth-aachen.de> Organization: EarthLink Network NNTP-Posting-Host: earthlink.net X-Newsreader: Netscape 1.1N Lines: 10 In article <1996Oct09.021718.4257@rwth-aachen.de>, skang@rwth-aachen.de (Sun-mi Kang) writes: > Demodulating the 14.2 Hz Stardust carrier: software update and benchmark results. > Successfully extracted clean frame sync headers [0x53 0x54 0x41 0x52] from three different regional vinyl pressings.
