Android Question change speed in mediaplayer??

[ilan]

hi

i am playing a mp3 file (about 1 min lenght) and always looping

now i would like to change the play speed, is this possible?

thanx

I believe that by changing the sampling rate, you can change the play speed. Double the sample rate to double the speed, or decrease it to its half to obtain half the speed, and so on. If the mp3 library you're using doesn't allow you to set the sample rate, switch to another library, or convert the mp3 file to a wav file and use AudioStreamer from Audio library to play it.

Hope this helps.

i am using the default mediaplayer lib and there is no sample rate
i will check the audiostreamer lib, thank you

You can use SoundPool from native Audio library to change rate

isnt soundpool only for sound effects? and not for background music?

You can change the sample rate with. Audiostreamer or Audiotrack, but be aware that the pitch of the playback will also change. If you want to change the speed without affecting the pitch you would need a specialist library like surina's Soundtouch, which.is.not yet available on B4a.
