I want to get the raw PCM output data in memory after all the dsp effects rendered, which is used for other processing. Currently, I can only write audios into wav files and read them back as pcm into memory. Due to some network issues in my environment, it costs a lot to write files, read and final…

It looks like your plugin description is missing the parameter definitions. For getparameterdata to work, you need to define that parameter. If you look at the dsp_custom example you will see dspdesc.numparameters and dspdesc.paramdesc are specified. You’ll want to copy this, specifically the waveda…

All of the callbacks shown in the dsp_custom example are optional, you can set it up simply like the example you found for Unity. For dsp_custom, you can simply use just myDSPCallback.

Thanks! That is the problem. I thought it is something optional like help message, so I skipped that part. I fixed it and now the code works. The DSP part: #include <fstream> #include "fmod.hpp" #include "common.h" typedef struct { float *buffer; int length_samples; } mono_pcm; // This d…
