Centralize the selection of codec compilation flags to codec.make to avoid having to duplicate the per cpu selection logic and the build rule in the individual codec lib make files and make tweaking easier. The two special cases, libmad and libspeex were left alone. I plan to introduce a var for arm generation so that appropriate flags can be selected per generation as benchmarking results have shown that different arm arches might have different optimal flags. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30330 a1c6a512-1295-4272-9138-f99709370657 |

TTA Hardware Players Library ============================ Version 1.2, (c) 2004 Alexander Djourik. All rights reserved. * Introduction This library provides to decode a multichannel 8,16 and 24 bits TTA audio files. TTA is a lossless audio format. Being "lossless" means that no data/quality is lost in the compression - when uncompressed, the data will be identical to the original. The compression ratios of TTA depend on the type of music file being compressed, but the compression size will generally range between 30% - 70% of the original. TTA format supports both of ID3v1/v2 tags. Detailed format description is available at http://www.true-audio.com. The decoder process has a minimal system requirements and does not required to create a big additional memory pools. As the TTA algorithms has a same system requirements both for decoding and for encoding processes - the TTA recorder can be easily realized also. * Changes 14/04/2004 1.0 Initial release 16/04/2004 1.1 Code optimization Code clean-up 29/10/2004 1.2 ID3 tags support Code clean-up * To Do - TTA recorder functions. * Developers Alexander Djourik <ald@true-audio.com> Pavel Zhilin <pzh@true-audio.com> * Copying Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met: 1.
