The Advanced Sound Retriever function enhances compressed music formats,
such as MP3, WMA or AAC and restores the music dynamics and harmonics
to CD-sound quality.
The benefit is that you can enjoy your digital music enhanced to near CD quality.
The CD -> USB recorder feature is an MP3 creator (MP3 encoder). The
tracks of audio CDs loaded in the player can be ripped on a USB device
connected to the USB port.
Simply select the CD tracks you want, choose the quality for conversion
to MP3 format and the DVD player will record everything onto your USB
stick.
