Audio Duration from Audio Player and WaveFormView not matched

[tutysathish]

I facing one small issue.,
Same audio I was loaded into AudioPlayer as well as waveform view
Both classes return an audioDuration for example

int audioDuration = AudioPlayer.getDuration(); //Example value:15935
int mPlayEndMsec = mWaveformView.pixelsToMillisecs(mEndPos) //Example value: 15900

So, I can't identify the user select the exact end position of the audio because selected Value (mPlayEndMsec ) not matched with actual value (audioDuration ). Is there any workaround is there? Please guide me with some solution.
