[SoX-users] Ogg Vorbis support in Sox

[<vo...@as...>]

I've been working on adding support for the Ogg Vorbis format (see
http://www.vorbis.com/ for more info) to the CVS version of sox.  So far, I
can use a vorbis file as input without any problems.  I'm currently trying to
decide how best to implement the output half of the vorbis driver, though.

I need to be able to pass to the vorbis driver--in addition to the normal
channels, bits, sample rate stuff--a value representing the desired target bit
rate for the output.  Vorbis files can encode with a variety of bit rates,
with the usual tradeoff that high bit rates == higher quality, but bigger
output files.  Anyway, I can't see any way to pass this information to the
vorbis driver using the current API sox uses to talk to the drivers.

Does anyone (preferrably sox developers) have any advice?  Is it even worth it
to support encoding of vorbis files in the driver?  It is very computationally
expensive, and there are other encoders that are more suited to vorbis
encoding.
