[flac-dev] Changelog: improved decoding
There's an entry in the changelog: Improved decoding efficiency of all bit depths but especially so for 24 bits (lvqcl) A couple of comments: 1) The patch that improves encoding for all depths was proposed by Miroslav Lichvar http://git.xiph.org/?p=flac.git;a=commit;h=4eab6313cd2198b5647d925bdb3847590505fa21 2) Performance checks graph posted by Martijn van Beurden reminded me that the decoding improvements for FLAC were made only for 32-bit x64 architecture (aka IA32). FLAC is multiplatform, so it make sense to mention this. ___ flac-dev mailing list flac-dev@xiph.org http://lists.xiph.org/mailman/listinfo/flac-dev

FLAC is multiplatform, so it make sense to mention this. IIRC for other archs most of the decoding speed improvement was already in 1.3.0. That's where the C version of the read_rice_signed_block function was optimized. Now in 1.3.1 it's enabled also for x86, but the difference between the x86 assembly and the C function is much smaller. -- Miroslav Lichvar ___ flac-dev mailing list flac-dev@xiph.org http://lists.xiph.org/mailman/listinfo/flac-dev
