Editing a digital voice recording: 1: Converting the WAV fileJune 1, 2008
Audacity didn’t recognize the WAV file from my DVR when I tried to open it using File > Open, even though Windows Media Player played it in its native format without any problems.
I searched Audacity’s (unhelpful) Help file for clues, then the internet. Some clues later, I tried importing the file (Project > Import Audio), but that didn’t work, and nor did importing it as a Raw file (Project > Import Raw File) which was Audacity’s suggestion in the error message.
Back to the internet where I found another clue—try opening the so-called WAV file in Windows Sound Recorder (Start > Programs > Accessories > Entertainment > Sound Recorder), then save it as a WAV file again (File > Save As). That worked—or so I thought. I now had a WAV file that Audacity could import. But only a few minutes imported. Actually, the entire 75 mins imported, but it was compressed into these few minutes which meant I sounded like a chipmunk on speed!
Off to Google again where I found a forum post that suggested using Switch audio converter. So I downloaded and installed it, then successfully converted the DVR’s WAV file format in to a recognisable WAV format. Now I had 75 mins of real time audio which I then imported into Audacity (Project > Import Audio).
