Hi,
I'm developing the sound system for a simulator, but I don't have so
much experience on this. I'm working with directSound and I use a
SoundBlaster Audigy2.
I have some questions:
When I play hardware buffers I detect a little delay of some
milliseconds, just when I call the Play function, when I play software
buffers this delay is far more smaller. The problem starts when I play
many hardware buffers at the same time, everything goes all right once
they are playing, but I have this little delay every time I try to play
them. Is there any way to avoid this little delay? Why does it happen?
Shouldn't a hardware buffer be faster than a software buffer?
Another one,
Which is the optimum frequency I should use for applying sound effects?
I mean, for instance, if I have an engine sound and I change volume and
pitch to it deppending on the engine's state, how often shall I call
SetFrequency and SetVolume functions? as they need some time to be
executed I would like to know which is the minimum frequency they should
be called. Right now I apply this effects every 16 milliseconds, 60Hz,
but I think this is way too often.
Thanks!!!
