TTA stands for The True Audio codec, which is a lossless compression format for audio, just like FLAC and APE – albeit with up to 30% smaller file size. In the same way ZIP, RAR and 7z do not alter the original data, True Audio codec also leaves the source audio data untouched.

What’s so good about TTA?

It only has one compression option, which leads to simpler usage. Some people also prefer that it does not support embedded metadata and keeps the audio pure. This is why an accompanying Cue Sheet is quintessential to the completeness of this format.
