[NaN]

I think I am starting to get an idea of what is going on. With 24 cars I counted up to 528 sound sources, with a maximum of 278 active at once. 10 cars max out at 120/310. Crazy shit huh..

The actual problem is that there is too much going on in the sound callback, which is executed asynchronously and has a hard timing limit depending on sampling frequency and buffer size. Anyway the current implementation is not even thread safe. It could happen that a source is updated by the game(position, pitch, gain) while it is sampled in the callback. This issues can be fixed by moving most of the calculations out of the callback and passing sound source state copies(currently pointers are passed).

I am wondering if we could avoid reinventing the wheel here. Are there sound libraries for games(low latency) out there that can deal with a decent amount of dynamic sound sources with variable pitch and have a somewhat usable api(c++)?

Back to sound hacking...
