Pretty much got a proper core written for an Audio file processor now.

I have another simple question about MPEG Audio files.

Am I ever likely to encounter an MPEG Audio file which will contain AUDIO
frames which differ in VERSION, LAYER, SAMPLERATE and/or CHANNELS? Eg.
Some frames are 48KHz and other frames are 44.1KHz ...or some frames in
Stereo, some in Joint-Stereo?

I have been unable to find any documentation which explicitly states
whether this should or shouldn't be allowed by the MPEG standard, and
nothing to say explicitly whether any players do or don't support this type
of change.

There is no reason why not, the file would have a valid structure - but it
seems unlikely.

This is relevant to creating the Xing/Xing or Xing/Info frame for VBRFix.

Thanks for any help,

BC
