What is Sony atrac?

Adaptive Transform Acoustic Coding (ATRAC) is a family of proprietary audio compression algorithms developed by Sony. ATRAC allowed a relatively small disc like MiniDisc to have the same running time as CD while storing audio information with minimal loss in perceptible quality.

How good is AAC format?

AAC (Advanced Audio Coding) and MP3 (MPEG-1 Audio Layer 3) are lossy formats for audio files. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at similar bit rates. This difference in quality is more obvious at lower bitrates.

What is the difference between ATRAC and MP3 and AAC?

ATRAC is dependent on it’s bitrate while MP3 and AAC uses a different algorithm for compression. For higher bitrates, ATRAC produces the same sonic quality but has a smaller footprint than MP3 and AAC.

Is the PS3 audio CD backup format the same as ATRAC3?

Yes, the PS3 audio CD backup format is “ATRAC3” (I think it uses an “aa3” extension, as encoded by the PS3), while the format used in games (especially for XMB icons with sound) is “ATRAC3plus” even though it uses a confusing “at3” extension! And neither of those are “ATRAC 3” with a space in the name, which is older and used in Minidiscs…

What’s the difference between airtac and ATRAC?

AAC should provide excellent quality, but MP3 should work well enough, and will be compatible with everything. ATRAC on the other side, I never really used, and that’s a proprietary format that will require a 3rd party player/plugin to work most likely.
