JOINT STEREO is the default mode for stereo files with fixed bitrates of 128 kbps or less.
At higher fixed bitrates, the default is stereo.
For VBR encoding, jstereo is the default for VBR_q >4,
and stereo is the default for VBR_q <=4.

JOINT STEREO will effectively increase the bandwidth
if the signal does not have too much stereo separation.
