What I would first check for is that the stuff making the noise that is filling the buffer is not putting any silence in there.

I would suggest simplifing and try filling it completely with white noise to see if there is any break in the white noise or not. Either that or logging each byte created by that

[source lang="c++]
for(int i = 0; i < samplesPerBuffer ; i++)
DelayA.push_front(-DecayFactor * DelayB.front()); DelayB.pop_front();
DelayB.push_back(-DecayFactor * DelayA.back()); DelayA.pop_back();
PickUpA--; PickUpB++;

Data16 = (*PickUpA + *PickUpB) * 32767;
Fin.push_front(*PickUpA + *PickUpB); Fin.pop_back();

... block of code, and checking that for silence.

Ugh... I found the problem; as usual it wasn’t my logic but some stupid little thing.


The samplesPerBuffer field isn’t actually “samples per buffer” but size in bytes which means that code works for AL_FORMAT_MONO8, for AL_FORMAT_MONO16 I need samplesPerBuffer*2 since every sample is 2 bytes.

No where in any Open AL documentation or example tutorial was that made clear.
I feel like I need to strangle somebody.
