I have another question…
This is my fmod setup:
I set system.setOutput to FMOD_OUTPUTTYPE_NOSOUND_NRT
2 sound streams, each with their own ring buffers and pcm read callbacks.
I will write data to each of their ring buffers, and they will read it in each of their callbacks.
I have a dsp added to the master channel group because I want the final mix of my 2 sound streams to write to disk. This dsp will write the final mix into its own ring buffer
This is what happens when my program starts, looping from 1-3:
1 - write data to the ring buffers of my 2 sound streams
2 - fmod.update
3 - read out the dsp data from the dsp’s ring buffer
However, it seems that the pcmreadcallback is not called before (3). It is only called around the 4th time fmod.update is called. This is causing my dsp to send back silent data for the first 4 times I call (3), and I think it’s causing some gapping issues too.
When/how does fmod determine when to call pcmreadcallback?
