Here are the result of my experiment.
I altered the popmute.py file values as:
I isolated the portion that I consider noise.
I analyse the segment using Analyze ⟶ Measure RMS to find the value as -87.1522 dB
The sound profile:
After various values, I find that with:
;control thresh "Threshold" real "dB" -37 -100 0
the profile isn’t changed in any significant way.
So my present confusion is this:
RMS shows -87.1522 dB of a noise segment.
popmute uses -37 to isolate that particular noise segment.
I find no parity or relationship between the two values.
But what I am able to do is to subject the entire file to the popmute.py with the value that I have set. Isolate the silence part that I consider as noise. Then use Truncate Silence… to remove the silence areas. Have only the noise profile. Then use this file as the one to use for Noise Reduction.
Hence, my other post at: What’s the path-directory where the Temporary file from “Get Noise Profile” is saved?
