As long as the audio of a video plays correctly in PTE, the way I understand it is that PTE will indeed export the audio to a separate and stand-alone WAV or MP3 file.This audio is 'copied' rather than extracted because the audio remains with the video file but it is available then as a separate stand-alone audio file. On the other hand, if from the timeline you click on the three bars to elicit the menu, you have a choice of exporting the soundtrack to either a WAV or MP3 file. In version 9, If you simply mute the video of an audio and choose from the 'Files of Type' two choices (audio files - video files) video files, then PTE simply uses the audio from the video to allow waveform manipulations on the timeline. I think perhaps there is some confusion about what PTE can do with audio from a video. Yes, muting of videos can still be handled though the O&A menu, to avoid simultaneous playing of the video's audio. After the video's audio is extracted, the users can do whatever they want with it but it really gives more flexibility to be able to adjust all the video's audio while the video is playing. I only suggest that feature be more obvious. I would use this to have the ability to adjust the volume of the video's audio, especially if I wanted to also have music playing in the background or for voiceovers. I found out about this some time ago, and then forgot where in the menus I could find it. My purpose of making this suggestion is that this feature is basically a 'hidden' feature.

This is sort of a kludge way using PTE to create an MP3 or WAV file from your video though it can be done. To make a stand-alone mp3 or wav of the audio from the video you would need to only add the video to your slideshow and no other sound.

But to make this work you have to also mute the video or you will have it playing simultaneously from the video and from the MP3.

Would you then handle the muting of the video or just be using PTE as a way of extracting audio from a video? The feature to 'add' the audio of a video as an MP3 to the timeline isn't really designed for the express purpose of extracting the audio from the video file, even though it can be done, it's designed to replace the sound from a video with an MP3 version which can be edited in the timeline.
