Dear Coders, am Simon.

Am writing to seek assistance in editing(removing unwanted noise, silence,... ) a .mp3 file. I was led to the website below. I've managed to look through the code snippets, and not yet succeeded . What could I be missing? Would you possibly guide me?

Unless of very particular cases, this is impossible (it's like to remove the ink from a colored water).

Independently on code, to remove "noise" and "other unwanted sources of sound" you need at least a secondary independent source correlated with those noises to elaborate a prediction filter that estimate the wave of the noise in the primary source.

Unless your "noises" fits a bandwidth that don't overlap your sounds: in that case a lowpass or hipass filter can be enough.
