1. The ISO 11172-3 standard says that the number of samples in layer 3
should be 1152. When I encode a single channel file lame sets the framesize
as 576. Is this an error or does the standard specify the size for dual
channel audio?

2. The framelength as specified in the standard is determined by the formula
'144*bitrate/samplerate' . But the distance between two frame headers in the
lame encoded bitstream is half of the value given by the formula. 

3. I am a little confused by the difference between a frame and an audio
frame. Does the information between two headers correspond to exactly 1152
samples or can this contain data about less/more samples.

Any feedback would be greatly appreciated.
