Trying to set playback rate on an mp3 file

AndrewPHanson

Hello Everyone,

I am new to Xamarin and working on my first android app. I am using a MediaPlayer object to load an mp3 file and play it back. I would like to set the mp3 to playback at 2x speed. When I look at https://developer.xamarin.com/api/type/Android.Media.MediaPlayer/ it shows there is a method for setPlaybackRate but I do not have that method on my object. Any ideas how to set the playback rate for an audio track?

Thanks,
Andrew

It looks like you can create a PlaybackParams object and set the speed and pitch in there. You can then set the PlaybackParams object inside the MediaPlayer object to your created playbackParams.

private MediaPlayer mediaPlayer;
private PlaybackParams playbackParams;

playbackParams.SetSpeed(2.0f);
playbackParams.SetPitch(2.0f);            

mediaPlayer = new MediaPlayer();
mediaPlayer.SetDataSource(path);
mediaPlayer.PlaybackParams = playbackParams;

I haven't been able to try it yet, but I'll give it a shot tonight and let you know if it works.

I confirmed that this worked. Hope this helps someone else.

Works for >=6.0, but what about older APIs?
