The best way to combine audio files in Android

Question

I am developing a recording application containing the Pause / Play option.

I tried with both Media Recorder and AudioRecord

In the case of AudioRecord, the recorded sound consumes a larger size, therefore, if the recording size increases, say, for example: if I record a 1-minute sound, it consumes from 40 to 50 MB, it is very useful to combine it by converting it to. raw file and send to php server .

So, I tried with Media Recorder , it consumes less size , but cannot be combined with the previous method recorded in Audio Record.

The next step I tried using the Android NDK is very useful even for the setup process.

Now my question is what is the best way to combine recorded audio files

• Using Android NDk
• Reading byte data from audio and combining. If I use this, the problem with recording format headers says amr, wav, like this.

Also, if I try with this , I cannot get the javax.sound package, so I tried using plugins, but no luck ..

Please suggest a better way to do this. I also tried with all of these following links

Audio Link 1

Audio Link 2

Audio 3

Audio Link 4

Provide me with a good tutorial or samples or links. Thanks.

Answer 1

For something like this, it is best to develop your own C ++ code using the NDK.
