+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. Detailed format description
+is available at http://tta.sourceforge.net")
