Several ways to do it, here is one:

Since you already have the audio in the timeline and unlinked from the video,
1) Click on the audio section and then the "Edit Audio" tab
2) WaveEditor will launch, simply close with the X in the right corner, a message about saving will appear, select yes
3) In the media library you now have a xxxx.wav file and the file is also on your hard disk in the current export folder

You can use the xxxx.wav file as you wish.

I recently created a "silly little video" making use of a one minute clip I'd taken back in May. During videoing I had chatted to my wife bemoaning how awkward the videoing was - this audio was removed and the background noises of bird song reused throughout the clip.

All I did was copy the audio clip, move the track scrubber to the end of the project and select Ctrl+V on my keyboard. I did that a few times.

As Jeff has mentioned there are a number of ways to isolate an audio clip and replicate.

Thanks guys. Both methods work. It seems to me that PD is a little quirky and not as intuitive as it could be. Why for example does the Control+V method work whereas copy/paste doesn't work?

Also, when using the WaveEditor method, why X out and save it (without any saving options) instead of using File/Save (from the file menu or the Save Icon). Neither is available here.

Admittedly small complaints (towards PD, not to the good guys here). HP Pavilion Elite 410f. AMD Phenom II 1045T (six core), ATI Radeon HD 5570 Graphics Card w/1GB, 8GB memory, terabyte HD, generic multi optical, LG BD burner, both Lightscribe, Windows 7 Home Premium 64 bit. Formerly used Ulead/Corel VideoStudio.

Paste and Ctrl+V - already mentioned to CL.

I found this old discussion dealing with same issue. BUT when I tried X method is WaveEditor, strange result.

I was not able to apply name to the WAV. BUT found a MP3 that was my correct 5 sec clip of 30 min project, under the project name in a different folder than project (but folder I used in project). It went right into project Edit box, had same name as project but since in another folder PD was fine with two same named MP3s (not WAV).

This is bizarre but just what wanted.

So 2015 the Wave Editor seems to still have a worthless File menu that does not even respond when you click save file or project, but if you "X" out, it clips the selected audio segment (a MP3) and saves to media box as MP3??!!

Why does the File Menu not work?

Thanks.

Darp1 - You posted on a 4 year old thread with a different problem. Need to start your own new topic. WaveEditor save in the wav format just fine. Just export it as a wav not mp3 file.
