ATRAC1 Encoded Audio

ATRAC1 Encoded Audio files are ATRAC1-compressed audio files used by Sony's MiniDisc system and similar ATRAC-based devices. These files hold audio that has already been recorded to ATRAC1 format rather than raw PCM. They are typically produced by dumping or ripping audio tracks from a MiniDisc in Sony's "SP" (standard play) mode. Once created, AEA files allow you to store or transfer MiniDisc audio in its original compressed form without re-encoding.

Because ATRAC1 is a lossy compression format, AEA files preserve much of the quality of the original MiniDisc audio, such as the 44.1 kHz sample rate and stereo channels, at a much lower bitrate than uncompressed CD audio. The encoding is fixed for ATRAC1 "SP" mode at approximately 292 kbps for stereo. Such files are often played or converted on a computer using software capable of decoding ATRAC1, or stored as an archival backup of MiniDisc recordings.

AEA files begin with recognizable identifiers in their data. Among the byte signatures are sequences like "DD32", "ETDD", "TD33", "UDC3", "UDDD", "UTDC", "VUTD", and a four-byte value 0x00080000 at offset zero. These markers help software determine that the file uses ATRAC1 encoding rather than another ATRAC family codec.
