Thanks, got there in the end

Steve: Thanks for clearing that up. It should have been obvious but I mis-read the timeline. Unfortunately, that still has not helped with the differences betwixt your spectrograms and mine. Below is the spectrogram of the waveform I uploaded and as can be seen there are no glitches as you have show...

The Audacity spectrograms seem to be showing a quite significant high frequency content from a voice recording!

@Steve: On page one of this post you stated:- Switching to the spectrogram view and zooming out a little (same selection): firsttrack001.png That red vertical bar shows the frequency representation of that glitch. Now lets zoom out a bit further: window000.png Holy smoke Batman, there's hundreds of ...
