I have about 1000 MP3 files that I need to perform noise removal on.
I have used Audacity in the past for individual noise removal operations but Audacity will not cut it for this job.
Audacity is unable to perform bulk operations and I don't have the time to perform this manually on 1000s of MP3 files.
The noise is similar to white noise but it differs slightly in every MP3 file, so a different noise profile will need to be built for each MP3.
The noise comes from a fan in the background (if you were wondering).
What is the best way to automate nose removal from the MP3 files?
You could try using Sox. It's a command line application so is scriptable. See here for further info.
