I have some mp3 files which also contain some crackle, static, pops, etc. This electronic noise I would like to remove with a filter. What recommended software can take an mp3 file as input, filter out the noise, and deliver a better sounding mp3 file as output? It was Audacity that I used to record the audio stream, and it was Audacity that added all the noise, noise which I did not hear over the speakers during the recording but only until the playback.
