Effect to audio and video file

Question

In my app I want to give effect to audio and video file like it is given to Pheed Application. I want to mix audio recorded sound with predefine clips. And also want to give sound different effect like echo , surrounding Normal , And with video file I want to add different effects like sepia,.. I don't know which class library I have to use to implement6 this . Can any one suggest me any library for that or any way how to do that?

Answer 1

Here are a pair of libraries you can try:

For audio filters and effects you can try with The Amazing Audio Engine . It is build on top of Core Audio.

For video effects try GPUImage . I haven't tried it but it is supposed to work better than Core Image when handling videos.
