Yes:
Bit 7,6 of the MPEG frame header:
00 LR Stereo frame (Stereo, Left + Right Channel, bit balancing possible)
01 MS Stereo frame (Stereo, Mid- and Side Signal)
10 Dual Channel frame (Mono, for instance dual language english/german)
11 Single Channel frame (Mono)
Ist it right that Layer II MS-Frames are unable to NOT use intensity stereo
for f > fs/4 (for CD 11 kHz)?
