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.

Dear friends! This project needs your donation, even if it's will be a very small amount of money. Please support our project! Feel free to request new functionality with your donation. The current objectives of the project are listed below. The development team thanks you in advance for your support!

Main features of the TTA lossless audio codec
  • Compression to as little as 30% of original file size
  • Realtime encoding/decoding algorithm
  • Minimal system requirements
  • Free and open source code and documentation
  • Compiles for several different platforms
  • Simple and convenient data format
  • Input plugins for various music players
  • Graphical user interface (GUI) for Windows users

The TTA lossless audio codec performs lossless compression on multichannel 8, 16 and 24-bit data of WAV audio files. The term "lossless" refers to the fact that such compression results in literally no data or quality loss; when decompressed, the audio file data are bit-identical to those of their originals. Compression ratios achieved by the TTA codec vary, depending on music type, but range from 30% - 70% of the original. The TTA lossless compressed audio format supports both ID3v1 and ID3v2 information tags.

The TTA lossless audio codec allows for the storage of up to 20 audio CDs worth of music on a single DVD-R, retaining the original CD quality audio, plus detailed information in the popular ID3 tag format.

All TTA source code and binaries are freely available and distributed under Open Source licenses. You may redistribute TTA freely as long as you do not charge for it. Please contact us if you would like to redistribute it under different terms.

Our current specific emphasis is on optimization of the TTA lossless audio codec algorithms for easy hardware implementation - not necessarily maximum overall compression levels.
