I am trying to re-encode some music files from Apple Lossless to FLAC[1] and there is a very short burst of white noise at the end of the file that every music player *except* Audacity can see.
Here's what I am doing. 1. Convert the ALAC music files to WAV (I was originally going straight to FLAC, but tried to cut some steps out in order to figure out which step in the chain was producing the white noise). Either of these tools produce the same effect: alac-decoder -f output.wav input.m4a ffmpeg -i input.m4a output.wav 2. Listen to the WAV files using any of the following tools: - totem - Squeezebox/Squeezecenter - Rhythmbox All of them render about 1/4 second or so of white noise at the very end of the playback. Further, this is preserved by "flac" when I convert the WAV file to FLAC. 3. Think "oh well, I guess I can edit the white noise off with Audacity!" Open WAV file in Audacity, discover that the white noise is not there in Audacity (not in the waveform, not present when I use Audacity itself to play it back) 4. Think "oh well, it's the least automatable setup ever, but if Audacity doesn't render the white noise, I can at least use it to export to FLAC!" Do so, and discover that the resulting FLAC files still have the white noise at the end when played in totem/Squeezecenter/Rhythmbox. I've also had a friend with Apple hardware (an iPod) play the original ALAC files and he reports that they do not contain a burst of white noise at the end. So I am out of ideas: does anyone know what the white noise is, why Audacity can't see it and thus let me edit it off but still renders it, or any tools that will allow me to produce FLAC files without a very annoying burst of static at the end? -Mary [1] I have Apple Lossless files because that's the only lossless format that The Dandy Warhols are selling The Dandy Warhols Are Sound in. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
