I have seen so many voice recording tutorials for Android but I did not find any tutorials for a pause/resume feature.

Can any one guide me? Is this possible in Android or not If it is possible, can you provide a code example?

AudioRecorder does not support pause/resume. You will need to stop it and restart it.

Also you'll need to concatenate audio files: Merging pcm audio files

  • so according to your solution i will have to stop it and then save file start again and merge these both files on final save? – UMAR-MOBITSOLUTIONS Sep 08 '11 at 20:43

    PCM is probably easiest because it only contains raw uncompressed digital audio data without any header or footer. So it's easiest to merge. – Peter Knego Sep 08 '11 at 21:03

    After you have a merged PCM data you can create WAV file: http://stackoverflow.com/questions/4777181/creating-a-wav-file-from-raw-pcm-data-using-the-android-sdk – Peter Knego Sep 08 '11 at 21:05
