Audio Crossfading in Android

Question

I am developing a media player for my learning purpose, and I want to have cross fading in a media player application. But I don’t know where to start. I tried searching on inernet but no luck. I use the Android MediaPlayer class for all operations related to the media player. Does anyone know a workaround to achieve the same.

thanks for your support

Answer 1

Try using AudioTrack instead of MediaPlayer. I usually suggest the following plan:

• Check out some sources for an application using AudioTrack. A good player can be found here.

This is an aac audio player that uses JNI to decode aac-audio.

• Find the MP3 decoding library. The library should be Java (see this , or maybe there are other libraries (I did not use such java libraries)) or the C / C ++ library (in this case you will also use it through JNI).
• When you get a simple working MP3 player, add manual crossfading (this should be easy if you know the basics of digital audio).

Answer 2

Try to use two MediaPlayer objects one after another with a crossfade, for example, in this class https://github.com/psaravan/JamsMusicPlayer/blob/f165057dd664727ed06b9fac2c27557e5fb7e7ee/jamsMusicPlayer/src/mams/java/er/er/er/play/er/play AudioPlaybackService.java
