I am trying to find out how to get the output sample data. So I can supply it to one of my encoders(for live streaming).
The first option I have looked at is using a custom DSP. It seems the sample rate is supplied with the callbacks in FMOD_DSP_STATE. I guess this is to encourage user to not assume a fixed sample rate? Now the issue is, is there a good way to get the samples along with essential information like the sample rate? Because the output stream needs a fixed rate.
Another option I checked is System::setOutput. This allows writing to files. But is it possible to have regular audio as well? It would be best to just have something like callbacks for output data.
If you’re creating the application as well as the DSP you can call System::setSoftwareFormat() before System::init() to fix the sample rate. All non-leaf DSP units will run at this rate.
However, on platforms other than Windows, the sample rate may be changed by the output driver. You should call System::getSoftwareFormat() after System::init() to check if this has happened.
