I'm looking for a way to batch process large amount of audio files (ogg and wav formats).
Ideally, a solution that works from a Windows' command line, allows conversion between formats, allows applying various effects (e.g. noise removal), delivers basic editing options (join two files together, remove silence from beginning and end of files, append 1s of silence to each file and so on) and it's freeware or open source. It can be a audio files editor with scripting capabilities.
Does anyone happen to know about existence of such solution? Any help would be greatly appreciated.
