How do I smaple the volume?

Mon Nov 13, 2017 7:08 pm

Suppose I want to sample the output volume of HDMI audio, e.g. 10 times a second. How do I do it?

I'm guessing you are not wanting to check what the volume knob is set at but want to sample the sound that is playing on the HDMI.

I don't know how to do it but I would look at software that has these features already, for example: https://learn.adafruit.com/raspberry-pi ... ghtshow-pi

Thanks. Yes, that looks like the kind of thing I'm looking for.
