Has anyone found a solution to the win32 sound recording latency
problem? I need to get smaller buffers (around 512 to 2k bytes or 30 to
125ms ) for a speech recognition app. It works fine in DOS and Linux,
it's just win32 that I can only get 1s recording intervals.
I tried experimenting with different values in the allegro source but
couldn't get it to work with smaller values.
i was unable to get allegro latency lower, so i tried using a library
called "port audio"
with port audio the latency is determined by the buffer size you supply.
too small a buffer just glitches, but i have successfully got 1k buffers at
44100 hz working.
this means 1/44'th of a second latency plus whatever internal latency
directSound has (which is un-avoidable).
