had to fix the subject... was getting under my skin! yeah, could you put up the FLAC version of the worst track that is less than 20 megs compressed? (I'll have to grab it with a 56k modem). by worst I mean the one where shorten beats flac by the most. also: 1. what version of shorten are you using? 2. what command-line options for flac and shorten did you use on this track? thanks, Josh

I've found a wav of an entire album that shorten compresses better than flac. Is this supposed to be possible? wav 388,374,044 flac-6 239,109,203 shn 236,457,697 Cheers.

Hi, How's the testing going? I compressed 194 individual .wav files (totaling 8.54GB) which contained tracks ripped from many varied albums. I unflacced them and compared their md5 signature with the same from the original .wav. They were all perfect. I didn't use the -V option just in case of any chance of mis-reporting. I hope to test it with the complete collection of ~41GB

The latest version of my cue+wav splitter supports .flac files. Hope to get it released this weekend. Will eventually be at: www.lameb.fsnet.co.uk It also supports .shn and .ape. I've seen shorten

You mentioned that one update was to include an md5 signature of the compressed stream to detect errors? Could you

Hi, I notice that this still doesn't work: $ shorten -x a.shn - | flac -V - a.flac You have to put the -fw in there: $ shorten -x a.shn - | flac -fw -V - a.flac Could wav format not be the default. Or even better could flac not auto-detact wav input, which is relatively easy? Cheers. Mark Powell - UNIX System Administrator - The University of Salford Academic Information Services,

Me too! Flac is one of the most stable, polished, and useful open-source tools I've used. Many thanks!

I just released FLAC 0.5 (Solaris binaries will show up tomorrow). FLAC is now beta; see the homepage as to what that implies: http://flac.sourceforge.net This version adds a MD5 signature of the raw audio signal to the stream header, which can be compared against when decoding to test the integrity of a file. A test mode (-t) has been added to flac to do just that. There is a slight

I found a bug with FLAC v0.6 raw encoding. It appears that the file pointer in the source file is not reset after seeking to the end for checking the size. I've attached a patch. I'm excited about FLAC!! I've been looking for a good GPL lossless RAW audio compressor for use with sound fonts. Sound font files contain 16 bit samples that are word aligned, so just treating it as raw

Josh, Those speed improvements are great. Quick test on an 365MB wav of Neil Young's eponymous 1st album on a PIII 650E (Coppermine) under FreeBSD 4.2: User Sys MB shorten23 0:46s 4.0 208.3 shorten31 1:24s 5.3 208.6 flac CVS 4:21s 7.5 199.2 It's getting near to be a useful replacement for shorten. Only 3x slower. Any idea why it uses so much more sys time? I would've thought

When offset + length == exts->end the code which is shortening the extents is subtracting 0 from length. And it is not optimized out.

When x101p clone receive ring signal from phone line, my voip phone start ringing. But, if caller hang-up at some time, phone continues to ringing 10 second more. How can I shorten that time? Pause betwen incoming rings on my phone line is 4s, so when x101p clone (wcfxo driver) do not receive next ring signal after 4.5 sec, call should be consider as ended. What should I change to set that time
