Antex electronic SX-33 Stereo System User Manual


 
39
In the Antex driver the bitrate is specified on a per-channel basis.
Therefore, requesting 64 kbits/s and stereo will result in a 128
kbits/s compressed MPEG stream. Supported bitrates (per chan-
nel) and compression ratios are as follows:
Layer I
32 Khz 44.1 Khz 48 Khz

384* 1.3 384* 1.8 384* 2.0
* These bitrates are available for mono files only.
Layer II uses a more sophisticated compression algorithm than
Layer I, so it is recommended that Layer II be used wherever pos-
sible.
