Audio editing in Android

Question

I am looking for some audio editing library which can help to mix two audio files into a single audio file. I don't mean concatenating file one after other. I want to mix second audio file in middle of random seek time of the first file as follow.

Track T1 : 1111111111 Track T2 : 2222

Output expected : 11112222111111

I want to achieve this for android application.

Answer 1

The only interesting and useful library I have found for audio editing is Ringdroid (available here: RingDroid Github).

You can check the source code in order to get some insights on how to do what you want.

Hope this helps for now!

Answer 2

The description of this project looks promising: musicg-sound-api .

This API allows developers to extract audio features and operate audio data like reading, cutting and trimming easily from an inputstream

However, the documentation is a little sparse.
