... the rest are off by a few bits.

The only way that can be true, is if

  • the sync mark itself is not meant to be on a byte boundary.

    Ie. If it is meant be a few bits into each frame?

    This is possible and easily dealt with.

  • Or the frames are themselves are "a few bits" longer than 960 bytes, which doesn't makes much sense.

    Could you unpack the first 3 or 4 frames of the (raw) file to binascii and post them on your scratchpad?

    Examine what is said, not who speaks.
    Silence betokens consent.
    Love the truth but pardon error.
