TTA1 - Lossless Audio compressor
================================

Version 3.2, (c) 1999-2004 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.

At now, mostly all of the popular lossless compressors gives a same
compression results (difference about 1-3%). 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.
