+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
+
