audioop. rms (fragment, width) ¶ Return the root-mean-square of the fragment, i.e. sqrt (sum (S_i^2)/n). This is a measure of the power in an audio signal. audioop. tomono (fragment, width, lfactor, rfactor) ¶ Convert a stereo fragment to a mono fragment.

python - audioop.rms() - why does it differ from normal ...

https://stackoverflow.com/questions/9763471/audioop-rms-why-does-it-differ-from-normal-rms

From the audioop page, it says that the rms calculation is just what you'd expect, namely sqrt (sum (S_i^2)/n), where, S_i is the i -th sample of the sound. Seems like its not rocket science. To use numpy, I first convert the sound to a numpy array, and always see identical min / max, and the same length of the data (so the conversion seems fine).

https://pydoc-zh.readthedocs.io/en/latest/library/audioop.html

The audioop module contains some useful operations on sound fragments. It operates on sound fragments consisting of signed integer samples 8, 16 or 32 bits wide, stored in Python strings. This is the same format as used by the al and sunaudiodev modules. All scalar items are integers, unless specified otherwise.
