True Audio (TTA): a free audio codec for audio compression

This is a free audio codec that enables compression without any losses. The True Audio format was developed by Russian specialists back in 2009. The main advantage of TTA is the highly efficient compression: up to 30% of the total volume. The original quality of the file is fully preserved. The encoding algorithm is implemented in real-time mode. The True Audio data format is simple and open; it is also suitable for lossless compression of multichannel files.
