I have an android mobile application that allows users to find background music from other users.
The objective for this project is to create an android view that allows a user to record to a selected track. Once the selected track is recorded to, I’d like the software to merge the two tracks together into a single audio file.
Please note that the final file is not a concatenation of two files but the mixing of one mono and one stereo file. One file is a background mp3 file and the other is a voice recording from the mobile device.
I have attached an activity file which has some workings of this but the version of ffmpeg(com.github.hiteshsondhi88.libffmpeg:FFmpegAndroid:0.2.5) used doesn't work for some reason.
