So I made 5 audio records using the default recorder in Android 4.4. All of them seem to have information because they have a size between 100MB-150MB. The problem is that some metadata was deleted, like length, bit rate, audio sample rate, etc. from all the files.
Because of this, I can't open the files. I want to be able to recover the file; I tried to use Audacity or Soundforge but it just plays static.
I read that by editing the hex I can modify the missing metadata but it didn't explain much more. Any help is welcome.
