WebService c# what library should I use for concatenating mp3 and merging pictures

[hogcia]

I have an assignment to do - I have to build a web service for:
- Analyzing text (done),
- Merging 2 images,
- Concatenating 2 mp3s (even with different bitrates).
What library should I use? How should I do this?
Thank You for Your suggestions.

P.S. We have to use DirectX

Well, you kind of answered your own question, no? If you have to use
DirectX, then that is the library package you use.

For merging the pictures, I don't see why you would need DirectX, unless
you are trying to make a video out of a stream of images. You can just use
GDI+ for that. How do you want to merge the images? What is the end result
when you merge any two images?

For concatenating two MP3 streams, you are basically going to have to
generate a filter graph and with a custom filter that takes two inputs (the
rendering for the two MP3s). You would then stream one through the output,
and when that is done, stream the second.

Hi,

Take a look around to see if there is some 3rdparty tool to handle mp3. I'm
pretty sure there should be.

I meant a concrete library - a dll, what to use with the using or a
reference.
Thanks for answering!

I think so too, but we have to programme this by ourselves.
