How to convert .pcm file to .wav or .mp3?

Question

I am currently developing an Android Application that has audio recording and playing. I am new to dealing with audio and I\'m having some trouble with encoding and formats.

Answer 1

I tried the above code for audio recording writeAudioDataToFile(). It perfectly records and convert the audio into .wav format. But when I played the recorded audio, it was too fast. 5sec audio completed in 2.5 sec. Then I observed it was because of this short2byte() function.

For those how are having same problem should not use short2byte() and directly write sData in line os.write(sData, 0, Constants.BufferElements2Rec * Constants.BytesPerElement); where sData should be byte[].
