There's something up with the file's specs.
Open the file in G Spot and note its Audio information.
Ideally it should list it as using the PCM audio codec and a sampling rate of either 44100Hz or 48000Hz.
Premiere Elements 13 on what computer operating system? Have you updated 13 to 13.1 yet using an opened project's Help Menu/Updates.
Regarding the narration .wav issue...
1. What device/program is recording the .wav file.
2. And what are the properties of this .wav file - is it pcm.wav or adpcm.wav?
3. If you create the narration clip with the Premiere Elements 14/14.1 Narration Tool, is the narration clip on the Voice track good with sound and waveform?
Please consider, and then we will decide what next based on the details in your reply.
I'm using version 13.1 on Windows 10.
The WAV was recorded using an unbranded dictaphone.
ADPCM compression (see above).
I've not tried using the native narration tool but can try if you need the answer to diagnose the problem.
I am 99.9999% certain that it is the ADPCM for your wav file that is causing the problem with Premiere Elements.
This is what I would like you to do to bring to 100% sure. Take your ADPCM.wav file into iTunes and convert it to the WAV version which should be using PCM instead of ADPCM.
Then import that PCM wav file into the Premiere Element project. The topper will be creating a narration with the Narration Tool in Premiere Elements and determining if that works.
The how to for the suggested iTunes conversion of your ADPCM to PCM wav can be found
Any questions about the above, including the how to for the conversion, please do not hesitate to ask.
The ADPCM vs PCM issue has been brought up several times in the past. This solution should work.
Let us see.
