I?m developing an application that needs to record audio and also draw
graphics at 30fps. Using a 32kHz sample rate the vorbis decoder causes
choppiness in the graphics because we will typically only do any
compression roughly every 1/16 seconds (2048 sample window size) so we
take just a little too long to process every second frame.
We have no preemptive multithreading but I can fix this problem by using
the settings in ve_setup_22_uncoupled for 32Khz samples. This results
in a smaller window size and means I do some processing every frame.
* What are the trade-offs here? It's spending a little more time doing
the encoding but does this also affect quality?
* Is this the best way of doing this?
* Is it possible to have more control over the window sizes? Just
changing the numbers in blocksize_short and blocksize_long causes a
crash so it's obviously more complex than that.
