Hi,
in that case you can just skip the right number of frames before starting
playing sounds.
I modified my code to take the start time for each file and schedule the
play time with frame accuracy.

If you want your timing to be sample accurate the algorithm is a bit more
complex.

I've been knocking my head against a wall for
more than a year trying to
I'm not simply trying to mix two files. My main project is a game engine
in which two sounds are allowed at any one time. For instance, there can
be constant background music punctuated by sound effects. I can't get
these to mix correctly.
figure out how to correctly mix two streams of
audio while using
libsndfile for input and libao for output. My main requirement is that
I cannot assume anything about the output drivers -- that is, I cannot
depend on the output driver (ALSA, OSS, Sun, etc) being able to do the
mixing for me. Many of my target platforms lack any sort of mixing
services. I need to do this myself. I tried starting a mixer/player
thread that would work in a producer/consumer relationship with one or
two audio file decoder threads. I can play one sound at a time just
fine. When I try to do both, I get distortion followed by a segfault.
Hi,
not sure if I understood correctly: do you just want to mix N files?
Like you I'm learning libsndfile and libao so this is my attempt to mix
some audio files:

P.S.
Can someone explain line 88 (I already read the sndfile FAQ)?
