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.

Can you not create a third audio file , add 1111, then append 2222 and then the remaining 111111 ?? — rfsk2010, Nov 25 '11 at 10:09
@Rihan I am searching for the same library which can give me functionality to split the file into two and then i can concate those 3 files one after other. And i need to port this for my BB app — Javal Nanda, Nov 25 '11 at 10:11
When you say "mix" what is your desired output, audio out of the blackberry speakers or a WAV file? — donturner, Nov 29 '11 at 08:59
a WAV file , or an audio file in any of the supported format amr,wav or mp3 — Javal Nanda, Nov 29 '11 at 09:24
@JavalNanda I need to overlap(not concatenate one after another) two or more mp3 files . May be you know how to do that in android as you worked with audio file formats in android. I have searched alot about overlaping mp3 files but no luck. Hope you have solution for my problem . Thank you Javal — Harsh, Aug 06 '12 at 05:57

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!

Hi, Ringdroid is an amazing Project. I just want to ask, if there is any Example of Merging 2 Audio Files. I have downloaded the Source provided on Google Code, But it doesn't have any Method for Merging Sound Files. Any help is Highly Appreciated. – Salman Khakwani Oct 22 '14 at 10:53

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.
