Padding in layer II about twolame HOT 2 CLOSED

I have not had any experience of anyone setting it one way or another.

Wikipedia says:

MPEG-1 layer I was also used by the Digital Compact Cassette format, in the form of the PASC audio
compression codec. Because of the need of a steady stream of frames per second on a tape-based
medium, PASC uses the rarely used (and under-documented) padding bit in the MPEG header to
indicate that a frame was padded with 32 extra 0-bits (four 0-bytes) to change a short 416-byte frame
into 420 bytes. The varying frame size only occurs when a 44.1 kHz 16-bit stereo audio signal is
encoded at 384 kilobits per second, because the bitrate of the uncompressed signal is not an exact
multiple of the bitrate of the compressed bit stream.

So it is about bringing the MPEG Audio stream up to a constant bitrate - but resulting in less audio per bps.
