Lightbulb An easy method using software only

I came across this thread with the same problem of extracting WAV files from PWI files. I found a technique that works entirely through software with no need to modify anything on the mobile device.

In the PWI files the WAV file is stored at the end of the file. All that needs to be done is to delete everything before the WAV portion and then save the remaining data as a new file. Here is an easy method to do this using a freeware hex editor.
  1. Transfer the PWI files to a PC using ActiveSync.
  2. Open the PWI file in the hex editor XVI32. All following steps are in XVI32. http://www.chmaas.handshake.de/delph...vi32/xvi32.htm
  3. Search --> Find
    • "Text String" should be checked
  4. Enter the following text in the search field: RIFF
  5. Click OK
    • The "R" in RIFF will be highlighted in the window on the right
  6. In the window on the right, select the character before the R in RIFF. That is, select the character to the left of the R in RIFF.
  7. Edit --> Delete to cursor
  8. File --> Save As --> Filename.wav
Filename can be anything you like, but it needs to end in .wav.

WAV file headers begin with "RIFF" so this is just deleting everything before it and saving the rest, leaving only the WAV file.

Enjoy!
