Recording mode (Bit rate)
This is a measure of data volmne per second. The rate is expressed in bps (bits per second).
in SonicStage, the bit rote can be selected for recording an audio CD or converting MP3
and WAV formot audio files into P_I'RAC3 formol from among lhree rotes: 132 kbps, 105
kbps or 66 kbps. In the case of 105 kbps, I05,000 bils ofinfbrmation is processed per
second, if the bit rate is large, thor means a large amount of intbrmation is used to play the
music. Thus, 105 kbps data produces better sound quality than 66 kbps dora, and 132 kbps
data provides better sound quality thon 105 kbps data. However, audio files in formots such
as MP3 have different encoding melhods, and so _he sound quality is not determined by the
bit rate alone.
