Audio CD Import
Adjust settings for the codec / bit rate used when importing (recording) audio CDs to the system storage.
Set the file format for music data recorded in the system storage. Select from AAC, MP3 and ATRAC.
To use ATRAC format files, go to (Settings) > (System Settings) and set [Enable ATRAC].
Set the data compression ratio when recording audio CDs. The available bit rate values vary depending on the codec setting. In most cases, a higher bit rate will yield better sound quality but also a larger file size.
