What are TTA files and how to open them

Are you having problems opening a TTA file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your TTA files.

What is a TTA file?

A .TTA file is a TTA True Audio Lossless Compressed Audio file.

TTA True Audio Lossless Compressed Audio is a file format for storing digital music in a way that preserves every bit of the original audio while reducing file size by typically 30-70 percent. These files are created by compressing uncompressed WAV-format audio data (8-, 16-, or 24-bit, possibly multichannel) using the True Audio (TTA) codec. After compression, the audio retains identical sound quality to the original, making this format useful for archiving music without loss of fidelity.

Files with .tta are produced by encoding software using the True Audio codec. Once encoded, they can be played back by programs or hardware that support lossless audio codecs, often requiring a specific plugin or filter if the media player does not support TTA natively. The format also supports metadata tagging (such as ID3v1, ID3v2, and APEv2) so album, artist, track title and similar information can be stored within the file.

Internally the file begins with the ASCII signature TTA or TTA1 identifying the version. The header records information like channels count, sample rate, bit depth, and total sample count. Audio is divided into frames of roughly one second each; each frame's data is compressed (using methods including residual coding via adaptive filters and Rice coding), followed by a CRC32 checksum for error detection.
