Here is my current approach, given I have an audio composed of 6 channels. To calculate the volume level at time T: For every channel, calculate the RMS value of 200ms window (44100 * 0.2 = 8820 samples, in my case). Time T will be in the middle of the window (ignore the edges). Calculate the average of the 6 values obtained in step #1.

PCM Audio and Home Cinema. PCM audio is used in CD, DVD, Blu-ray, and other digital audio applications. When used in surround sound applications, it is often referred to as Linear PCM audio or Linear Pulse Code Modulation (LPCM). PCM audio produces a series of numbers or digits, and hence this process is called digital. Each one of these digits, though in …

You might want to define volume level more accurately to get to specific formula. Loudness of PCM stream question/answer gives one the popular options.. Your 32-bit INTs don't look good, by the way.With 16+ bits/sample integers, the samples are typically zero-centered (that is, you are to treat them as signed integers!) and the value sequence in your question more …
