TTA

TTA. TTA is a lossless audio codec developed by True Audio, a company founded by Alexander Daryin and Sergey Shkurov, in collaboration with Microsoft Research and Dolby Laboratories. The development of TTA was influenced by the work of Karlheinz Brandenburg, the creator of MP3, and Florian Camerer, a renowned audio engineer. TTA is often compared to other lossless audio codecs such as FLAC, developed by Josh Coalson, and ALAC, developed by Apple Inc..

Introduction to TTA

TTA is a free, open-source codec that supports multi-channel audio and is compatible with various operating systems, including Windows, macOS, and Linux. The codec is widely used in the audio industry, particularly in the production of DVD-Audio and SACD discs, which require high-quality, lossless audio. TTA has been adopted by several audio manufacturers, including Sony, Philips, and Denon, and is supported by popular audio players such as VLC media player, developed by VideoLAN, and Winamp, developed by Nullsoft. TTA is also used in the production of audio for film and television, with companies like Warner Bros. and BBC utilizing the codec.

History of TTA

The development of TTA began in the late 1990s, with the first version of the codec released in 2001. The codec was initially designed to be a competitor to MP3, but it later evolved into a lossless codec, with the goal of providing high-quality audio without any loss of data. TTA was influenced by the work of Nikolai Chernov, a Russian mathematician, and Leonid Levin, a computer scientist, who developed the LZW compression algorithm. The codec has undergone several updates and improvements over the years, with the latest version, TTA 4.0, released in 2010. TTA has been used in various applications, including audio mastering and sound design, with notable users such as Brian Eno and Hans Zimmer.

Technical Overview of TTA

TTA uses a combination of Huffman coding and arithmetic coding to compress audio data, resulting in a lossless compression ratio of up to 30:1. The codec supports a wide range of audio formats, including PCM, DSD, and MPEG-4. TTA is also compatible with various Digital Rights Management (DRM) systems, including Windows Media DRM and FairPlay. The codec has been optimized for use on various platforms, including ARM and x86 architectures, and is supported by popular audio libraries such as FFmpeg, developed by Fabrice Bellard, and LAME, developed by Mark Taylor. TTA has been compared to other lossless codecs, such as WavPack, developed by David Bryant, and Monkey's Audio, developed by Matthew T. Ashland.
