Hi all, I just finished running the scripts I used to write the lossless audio codec comparison that is on the FLAC website. The results are in the PDF linked below. As you can see, compression is exactly the same but decompression is about 15% faster. As expected, all results were lossless. http://www.icer.nl/misc_stuff/FLAC-1.3.0-results.pdf For more information on the used test corpus see http://flac.sourceforge.net/comparison.html. I ran the scripts 3 times, once with FLAC 1.2.1 as shipped with Kubuntu 12.10, once with FLAC 1.2.1 as compiled from the sources and once with FLAC 1.3.0pre2 (commit 300d17c). This test took about 12 hours.

" .. is the OS in 64 bit mode ? which CFLAGS where used and what compiler ?

" .. is the OS in 64 bit mode ? which CFLAGS where used > and what compiler ?It's 64-bit, I just ran configure with no options specified. I don't know what flags or options were set by the debian packagers, that's why I built FLAC 1.2.1 myself and tested too, to exclude effects of any compile time options. So just ./autogen.sh; ./configure; make; make check, so it was compiled with GCC.
