Is there a fastest way to get the PCM of microphone input? I’m looking at the record and customDSP examples, but since I don’t need i.e. to play back the sound, record it to disk, or perform any effects with the dsp, I am wondering whether things can be cut away or for shortcuts to increase speed.
For example, should I obtain the PCM with getMeteringInfo or directly with a custom dsp callback?
naively I’d try to:
make the sound & custom dsp, start recording and then in loop query the dsp’s *inBuffer.
