processor usage

[koen]

Hi Forum,

I have a question regarding the AudioProcessorUsage() function. Is this measuring the cpu usage of the Teensy or the cpu usage (if applicable) of the audioshield?

Teensy... the audio shield is just doing the conversion and analog duties.

It's the CPU usage on Teensy.

Graphically speaking, AudioProcessorUsage() measures this:



It captures all the CPU time spend doing non-I/O work like reverb, waveform synth, and effects processing. It also captures part of the work involved for receiving and sending digital audio data to/from the audio shield, but measuring the portion done in the higher priority interrupts is imperfect.

Thanks, that is clear. Anything on the Teensy between input and output in the audio library objects.

Thank you
