Is it possible to “filter” MP3 files to remove noise etc?
Well, you can’t really filter MP3 files. You can alter the *playback* by using equalizers and various plugins. But if you want to apply filters to the file, you’ll have to decode it to WAV format. Any good WAV editing program can do all sorts of filtering, but I don’t know exactly what you need. Try Goldwave (www.goldwave.com). Experiment with noise filtering or maybe even pass filters. However, if you’re referring to the kind “flanging” sounds that bad VBR or joint encoding can produce, then I think you’ll find them very hard to hit with filters…
