Peak Level Meter
A couple of years ago I’ve created a bunch of simple audio utilities for various larger projects. I’ve updated some of them to include on my website, so possibly someone can learn something from it.
This is one of those utilities, that does nothing more than display the current audio input level.
This example uses the Low Level waveform audio services to ‘capture’ the input data and then calculates the maximum level for each data block (20 times per seconds).
As an extra feature I’ve added the class COscilliGraph which shows all sample values in a simple graph (just for the fun of it..).
My CVuMeterCtrl control is used to display the peak level.
