%description
The True Audio (TTA) codec is a free, simple, realtime lossless audio
compressor. Based on adaptive prognostic filters, TTA has compared
favorably to a majority of its popular open-source peers. The codec was
built to offer adequate compression levels while maintaining high
operation speeds.

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 format supports both of
ID3v1/v2 and APEv2 tags.
