clean up and convert wav 2 mp3 with sox
 
Hey all,

I'm currently in the Philippines doing some research and I am using an MP3 player to record my interviews. It stores them in ADPCM wav (i think). I want to convert them to mp3 files to reduce storage space. I discovered sox, which i have used to convert them to mp3 and increase the volume 150% and this is a good start but i would like to "clean them up" (like they do in teh movies) - however, i don't really have any idea of what this might require.

The majority of the recordings is just speech so i figured some of the passes might help?

Suggestions for a quick and easy combination of filters would be much appreciated - my Masters is in Disaster Management, no in sound engineering, so would prefer to avoid too much reading!

Hi.

You'd probably get the most benefit from normalising your audio files (making the loudest part of the file 0dB).

You can get a normaliser here:

This page also has some useful utilities:
