I'm trying to create a karaoke dvd and have worked out a solution that works for video but now I need to sort out the audio stream so it's in sync with the video.
Effectively I need to take a series of audio files (mp3 files but I'm reencoding them anyway, so uncompressing them first won't be a problem), I then need to pad each one individually with silence to make it up to a specific length (a different length per file) and then I want to concatenate them all together for encoding to ac3/mp2.
Can anybody recommend any audio processing libraries or command line tools to automate this for a selection of files?
