Frequency analysis in Sound Forge suggests that the sound's frequency
extends from low to high; it's very broad. If I am reading the tool
correctly it is a bit louder at the lower frequencies.
My sound guru says that the lower frequency are the most troublesome.
If one can get rid of them, one is better off. He says to use a high
pass filter. He suggests that one needs to experiment with the range
of frequencies. He said that he would then pump up the mid range
frequencies.
He said to use the high pass filer to do this. Does someone know the
analogous tool in Sound Forge 6? I am a dummy. Only used Sound Forge
for simple stuff.
By the way, this is essentially a video of a PowerPoint presentation.
PP slides and talking head. (I know, I never let them do it again.)
However, I converted the PowerPoint successfully with Camtasia.
(Client bought it with no problem.) Hardware conversion was done as
well but it was muddly and blurry. Not close to useable.
