Hello,
I am experiencing a strange issue with openAL and iPhone SDK.
Suppose I have three sources that play very short sounds:
s1, s2, s3
I want to play repeatedly
s1s2 s3 s1 s2 s3 s1 s2 s3 .... (loop)
the sources all have a different gain. It looks like the effective
gain of s1 has an influence on the gain of s2, except when gain of s2
is 0.
More specifically, if gains are 1.0, 0.1, 0.5, the second source will
actually have a gain very close to 1.0. Conversely, if I turn of s1,
s2 will play with the "expected" gain.
Is is something that we can explain ? Also, when I slow down my loop
I still observe the same thing.
Is is possible that in openAL the gain applied to one source
influences the gain of the sources played after it ?
I hope my example is not too obscure and somenone has a clue for me.
Regards,
Romain Pechayre
