DO > you have any test scripts your use to run your tests?Sorry, most of the testmaterial isn't copylefted, and I don't think it is possible to get a nice copylefted test library. That's because most copylefted material is indie, and sadly the mastering techniques usually differ quite a lot with those used of regular commercial stuff. The scripts I use are written in PHP and rely on quite a big variety of linux-specifics. For compression it's probably not necessary anyway: the scripts are written so that the test report accurate encoding and decoding speeds. So, if one has a nicely balanced pool of music/sounds just compressing it and checking the filesizes of each individually is probably the best way to do this. I do that last step by hand anyway. So, I don't think I can be of any specific help on this.

We would keep it as a separate git repo of test files, and we could probably just use snippets instead of whole peices and claim fair use: https://en.wikipedia.org/wiki/Fair_use Maybe we shoud collect some samples.

Currently measures just over a GB. For flac they only seem to have one sample plus a cover art sample. They use rsync to keep it synced. fate.ffmpeg.org Dave

Bandcamp (who make heavy use of FLAC on their servers) might know some of them, if anyone from Bandcamp is on the list. -- -Dec. --- "Mosaic is going to be on every computer in the world." - Marc Andreessen, 1994
