Audio level meter using Mixer API calls
Posted on 1997-05-13
I have to build an audio level meter. "VU-Meter"
Could somebody pass me an example code on how to take a peek at current wave audio level using mixerGetLineInfo, mixeGetLineControls & mixerGetControlDetails.
Correct me if I'm wrong, but I think audio card passes this information to you so that you can use Mixer API's to read the actual current "VU-meter" value and you don't have to calculate it yourself.
But the question is: How can I do it?
