Audio Formats and Quality

A variety of factors affect the quality of a digital audio file; most notably:

Higher sample rates result in better sound quality, but are usually larger files than those using lower sample rates. Compressed files are smaller but have slightly lower quality than uncompressed files. Different compression formats can also affect the quality. By default, Rhapsody imports CDs as 192Kbps MP3 files.

The following formats are available in Rhapsody for playback and importing CDs to My Library, as noted below:
