Audacity does not load entire .wav file

I’m editing a .wav file recorded from a voice mail message emailed to me by my voice mail provider, Segway. When I play the file in Windows Media Player the entire message plays. When I load it into Audacity, the last part is cut off. To clarify, the message is made up of as original VM at the end, comments by a second person as forwarded in the middle, and comments by a third person as they forwarded it to me. The first two parts are loading into Audacity and I can edit them. The last part, the original VM, is not loading and cannot be edited or played.

Speficifics: File type: .wav
Computer: Dell Inspiron N5010, intel Core i5 processor, 4 GB RAM and 500GB HD
OS: Windows 7 Home Premium 64 bit
Audacity version: 2.0.0 (Unicode)

I really need to get to that last portion of the recording and would appreciate any help anyone can provide.

Thanks

The desperation method would be set your computer up for What-U-Hear or Stereo-Mix and record the playback.

You might also need to install the FFMpeg software extensions.

You rang alarm bells here. Why would you want to edit somebody’s voicemail other than to make it appear that they said something they didn’t? Are you making a music video? Koz
