说明:  TTA的压缩算法,有兴趣的朋友希望能共同研究一下,同时寻求快速无损压缩的算法,希望有精于此道的朋友提供信息,谢谢!
(TTA compression algorithm, interested friends hope to jointly study, while seeking rapid lossless compression algorithm, with the hope of fact they were friends to provide information, Thank you!)

TTA1 - Lossless Audio compressor ================================ Version 3.3, (c) 1999-2005 Alexander Djourik. All rights reserved. TTA performs lossless compression on multichannel 8,16 and 24 bits data of the Wav audio files. 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 is a hardware-oriented format. It means that the TTA format has a reasonable compression level, but WAS NOT developed to show a top results in comparisons. TTA format supports both of ID3v1/v2 tags. Detailed format description is available at http://tta.sourceforge.net * Usage Instructions ttaenc [command] [options] file(s).. Commands: -e encode file(s) -d decode file(s) -dx decode file(s), wave-extensible -t test file(s) -f name specify output file name -v show codec version -h this help Options: -u delete source file if successful -s silent mode Example usage: ttaenc -e *.wav; ttaenc -d *.tta \audio When using wildcards, only the input name can be specified. The output names will be automatically determined as the original name with the new extension. * Features - Support of 8,16,24 integer and 32-bit floating-point multichannel Wav audio files; - Support unicode file names; - Minimal system requirements; - High compression performance; - High speed performance; - CRC checking; - Corrupted data decoding; - Simple and clean output files format with precalculated seek points table. * Developers Alexander Djourik Pavel Zhilin * Copying This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.
