Hi,
I'd like to take an existing mp3 file located on an SD card and arbitrarily crop it (e.g. crop from 0:12 to 1:14 in a 3 minute song).
The only class that I've seen that seems remotely relevant to do this is the MediaRecorder class. My 'hope' would be to "record" an existing file like this:
MediaRecorder recorder = new MediaRecorder();
recorder.setAudioSource(###some magical way of specifying an existing file??###);
But this obviously doesn't work (setAudioSource() takes an int and seems to default to the phone's microphone).
Is there a class or an approach that can be used to crop audio on the phone itself?
TKS!!
