combine multiple sound clips

[simp2611]

Hi,

Does anyone know how to combine several audio clips with its specified starting time, say in mp3 format, into a single audio clip?

Thanks in advance

Do you mean merge then into a single file or simply play several audio files back-to-back?

Thanks for your reply.

I need to merge them together acoording to each specified time as I need to synchronise with a video later by using Player.addController(). With multiple player of clips, it is quick infeasible to sync with the video player; that's why I want to combine all clips into one file.

Sorry, still not quite sure:

(a) merge then into a single file
(b) simply play several audio files (or sections of audio files) back-to-back?

I mean (a): merging clips into same file, but each clip start to play back at different times. For example,

clip A (start at 0 sec)
0 1 2 3
|-----|-----|-----|------>

clip B (start at 2 sec)
2 3 4
|-----|-----|----->

clip C (start at 3 sec)
3 4 5
|-----|-----|----->

After combined, the clips will be saved as a single file, but can be played simultaneously according to each starting time:

combined clip
A
|-------------------------->
B|---------------------->
C|---------------------->

I think you're just going to have to find a 3rd party library that supports MP3 editing - I don't think their are any libraries that come with the usual Java installation.

Sorry I should have clarified that Java Media Framework (jmf) is being used for this project. Do you know any java forum got people have experience in jmf?
