Music sources playable on this CD player You can play the following 3 music sources on this CD player: -Audio CDs -ATRAC3plus/ATRAC3 format files -MP3 files Usable disc forma ts You can use ISO 9660 Level 1/2, Joliet extension format discs only. ATRAC3plus and ATRAC3 ATRAC3plus, which stands for Adaptive Transform Acoustic Coding3plus is audio compression technology, developed from the ATRAC3 format. Though the ATRAC3plus format can compress music content to about 1/20 of its original size, you can still enjoy high quality sound. The available transfer bit rates are 64 kbps and 48 kbps. ATRAC3, which stands for Adaptive Transform Acoustic Coding3 is audio compression technology that satisfies the demand for high sound quality and high compression rates. The ATRAC3 format can compress music content to about 1/10 of their original size, which contributes to reduction of the media volume. The available transfer bit rates are 132 kbps, 105 kbps and 66 kbps. The usa ble n umber of groups and files -Maximum number of groups: 255 -Maximum number of files: 999 For details, refer to the supplied booklet SonicStage Simple Burner. MP3 files MP3, which stands for MPEG-1 Audio Layer3, a standard for audio files compression supported by the Motion Picture Experts Group, an ISO (International Organization for Standardization) working group, enables compression of audio files to about 1/10 of the data size of a standard compact disc. Since the MP3 encoding algorithm is public, there are various encoders/decoders that are compliant with this standard, including freeware that is available for no charge. Thus, the MP3 standard is widely used in the computer field. ATTENTION AU COMPOSANT AYANT RAPPORT À LA SÉCURITÉ!!
