I want to code a little Audio Visualization, and before I use C++ with SDL and FMOD I would like to know if it is possible to play a sound-file with heaps/hashlink and get to the bytes.
I think I’m looking for something like the (never working) OpenFL SampleDataEvent.
I need the bytes of the audio played at the moment to feed an FFT Algorithm with it.
Reading through the heaps source code didn’t help. I discovered NativeChannel has an onSample method which can be overriden, but this method is missing in the normal Sound Channel.
