I have a need to insert an audio watermark (basically an audio file repeating the name of the company) into thousands of audio files. I'm having a hard time finding software that can streamline this batch process. I basically need to merge a single audio file with thousands of others keeping in mind that the lengths of the audio files vary from 7 seconds to around 10 minutes.

Digi, SS, Nuendo etc., Design something that will save new releases and the future of the 21 century musician from total poverty due to piracy.
