What is an .AA3 file?
AA3 files are audio files saved in the ATRAC3 or ATRAC3plus format, a lossy audio compression technology developed by Sony. These formats reduce file size while maintaining good listening quality, and Sony commonly used them in their portable music players, MiniDisc devices, and some early digital audio software. AA3 files typically store music tracks or voice recordings encoded for efficient playback on Sony hardware.
You may encounter AA3 files when importing audio from older Sony devices, converting recordings made with SonicStage or OpenMG software, or accessing archived music libraries created in the early 2000s. File Viewer Plus can play AA3 files and convert them to modern formats, such as MP3 or M4A, at various bitrates and sample rates, ensuring they work smoothly on today’s devices and media players.
Alternate file extensions: .at3
