Well, as I said, OpenAL isn't really meant for what you're trying to
do.  I'm not familiar with the range of audio synthesis tools that are
available, or I'd probably recommend one.  You'll probably have fewer
headaches that way.

That's certainly true, but you'll have to make sure that the amplitude
(sample value) at the end of the first buffer matches the start of the
second buffer, or you'll always have clicks.

There's also alutLoadMemoryWaveform, which simply creates an array of
samples containing the desired waveform.  You should be able to use that
with any filters you like, then pass the results to alBufferData().

I'm not sure what you mean.  The duration you give the function
specifies the content of the generated buffer, so yes, it will stop
after the specified duration.
