[vorbis-dev] Suggestion for libvorbisfile: scaling

[Paul Martin]

I've been experimenting with the ideas of Replay Gain[1] and find that
ogg123 doesn't have a way of specifying the scaling applied to
replayed samples (like -f in mpg123).

Looking at libvorbisfile, I see no function exactly matching this
possibly desirable behaviour.

ov_read() scales by either 128 (byte output) or 32768 (word output),
but there's nothing in between.

ov_read_float() outputs floats, which is OK, but means more work in the
frontend program.

My suspicion is that floats are not used internally by ov_read(), and
there would be a speed penalty for using ov_read_float().

Anyone have further thoughts on this?
