I have made spectrograms and waveforms that play within powerpoint or
keynote by using iShowU to capture a Quicktime movie of the screen as the
sound plays. You can set it to capture just that portion of the screen that
you want and you can edit the start and stop points of the movie once it is
made. The Quicktime movie is embedded into the presentation and set to play
on click. You can make a screen capture of the first frame of the movie as =
a
place holder to display on the slide before the movies starts having the
actual movie appear over the place holding png image.
This is using a Mac. I am certain that there must be an iShowU-like
application for the PC.
I hope that this helps,

Dear Nature Recordists Group,
I have a query and would be very grateful for any suggestions that the user=
s
of this group may be willing to provide.
I am preparing a power point presentation to give a talk about some animal
vocalisations. I have seen talks in which speakers display a small
spectrogram on their slide. When this is clicked on the sound plays and a
pointer moves through the spectrogram simultaneously. Does anyone have any
pointers as to how this can be achieved?
I only have free downloaded programs 'sonic visualiser' and have used
another free program, 'wavepad sound editor', to cut the appropriate bit ou=
t
of the wav file and then run them through the sonic visualiser to get the
spectrogram. However, I am not sure how to extract the spectrogram from
sonic visualiser and suspect I will need to use another program for this.
Many thanks,
Claire Watson.
