similar to: Re: flac and pipes problems (was: Possible bug)

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

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.

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

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

Sorry, I don't :( I've split into individual files and

well, I took a look at the files. from my knowledge of shorten there are two things it does that flac doesn't do: 1. it estimates the mean of the signal for each block, subtracts it out and stores it separately. but this is pretty useless for the predictors that shorten uses as they are pretty insensitive to the mean (try different values of -m from 0 to whatever and note practically no

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

I've released FLAC 0.6. The big improvements are: - encoding speed in default mode (-6) is at least 3x faster - a new "loose mid-side" adaptive algorithm should help -1 and -5 modes - a new analyze mode for developers - a autoconf/libtool-based build system (thanks to Matt Zimmerman) - bug fixes related to pipes Check the new comparison page. FLAC has the best ratios of any open

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,

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

There is no configure

so you're saying it worked as expected with -8 but not with -6? (the default compression option). that would be very wierd. however there is a bug that happens in this case where stuff is added after the end of the data chunk without using another WAVE chunk. I've committed the fix (in src/flac/encode.c). it should now ignore anything after the end of the data chunk. Josh --- Mark

I have checked in all the latest into CVS and am going to start the test suite again. if all goes well I will probably release this as beta 10. this one should have all the configure stuff working with the new assembly infrastructure. I have tried to make it as easy as possible to port routines to assembly. all that's really needed now is to write the corresponding routine for a specific

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