I have a recorded lecture which I recorded on my mobile using smart recorder android app. This is a .wav file of around 180 mb.
There are following issues with it -
1) some places the sound volume is low.
2) There is disturbance in sound and although loud but one cannot properly understand what is the person speaking.
please suggest some tools which can remove these defects.
Main issue is to remove the disturbance so that one can hear words clearly.
