Settings > Music Settings > Audio CD Import
Audio CD Import
Adjust settings for the codec / bit rate used when importing (recording) audio CDs to the hard disk.
Codec
Set the file format for music data recorded on the hard disk. Select from AAC, MP3 and ATRAC.
Hint
To use ATRAC format files, go to 
(Settings) > 
(System Settings) and set [Enable ATRAC].
Bit Rate
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.
