I am a new user of NVivo 11. I am importing interview audio and time-stamped transcripts and finding that NVivo is not importing .MP3 audio correctly.
The problem (example):
I have an interview audio file of 1 hour 15 minutes, saved in .WAV format, with a file size of approximately 500MB. In order to reduce overcrowding on my desktop hard-drive, I compressed the file, converting it to .MP3 format. The new file is approximately 100MB, and still shows '1 hour 15 minutes' in the file>properties>audio panel.
When I try importing the original .WAV file into NVivo, the wave-form appears correctly, and the audio track length is correct (at 1 hour 15 minutes). However, when I import the (matching) .MP3 file, the track appears as over 3 hours long - 1 hour 15 minutes of audio plus over 2 hours of silence.
Why is this a problem? This means that when I import a time-stamped transcript, the audio and the transcript are no longer synced correctly.
Of course I can just go ahead and use the original .WAV files for all of my interviews - however this will quickly become infeasible due to the large file size.
Any suggestions about what might be causing NVivo to interpret the .MP3 files incorrectly, or how to solve this issue?
