can not import .wav file

win 7
files from one recording device (.wav) import with no problems into audacity
However, files from another recording device, ( also .wav) can not be imported.
If I try to import as “raw data”, it sounds like a 100x speed voice recording. Changing the replay speed does not help.
Files from both devices play hassle-free on Windows media player
Are there different .wav formats?
Any help would be appreciated

Before you go off making unwarranted assumptions, let’s tell Windows to stop hiding file extensions so you can tell what you really have.

– Hidden File Extensions
– Start > My Computer > Tools > Folder Options > View > [ ] Hide Extensions for Known File Types (deselect)
– Apply (to this folder) or Apply to All Folders
– OK

Once you do that, you may easily find that you really have an .m4a or other highly compressed file type, not a WAV.

You can open those up, but you need to add the FFMpeg software package to do it. Install from here.


This is a direct link to the instructions and download .


Thanks for the reply, but still, after following the instructions given, the files have the extension .wav
Same files are opened automatically with windows media player and they replay just as intended.
Files also open with vlc media player.
However, importing to audacity poses a problem.
Any more suggestions?


Programs such as G-Spot or MediaInfo can probably give more detailed information about the file type:

If all the files play with VLC this suggests strongly that Audacity will import them if you use FFmpeg as already suggested.

If not, try playing the files in VLC and recording them into Audacity ( see ) or use VLC’s feature to “convert” the file to “audio - CD” which is 44100 Hz 16-bit WAV.
