Editing the Audio

Hi,

I have a compact Sony miniDV camcorder and the audio
output from the camcorder always has the the annoying
noise (the motor noise) associated with it.

I know that i can attach an external mike , but that
would really defeat the advantage of a compact camcorder,
plus i will have to spend around 100$ more.

I tried editing the audio using MM2 but could not find
anything other than the option of adding another audio
track to the movie.

What i want to do is edit the original sound track and
use some kind of an equalizer to remove the noise.
Is this possible in MM2 ?
If not then would appreciate pointers to any other way of
doing it.


thanks,
Mahesh
 
Mahesh,

I know you can't do it with MM2. Others can offer suggestions on what to
use.
 
Hi there,

Using MM2 drag your clip to the AUDIO track and then save Movie using
DV-AVI output. This will create an audio only track with the extension WMA.
Then with whatever audio software you have that has the ability of a
Graphic Equalizer (Music Match Jukebox is one, perhaps Windows Media Player
as well) edit the audio to get the desired effect. Then add that back to
the original video clip and this time mute the soundtrack on the video so
that your new audio track replaces it.

HOWEVER. what you really need is something called a "compander"
(Compression Expander) I know you can get them for the PC, but have never
actually seen one. Before PC's became cheap you would buy a desktop
compander for one or more channels. You use them to compress a certain
frequency range so that it would look like a single peak on an
oscilloscope....then you would delete that peak with a filter and then
expand what was left back to its original frequency spread.

The reason I mention this is that the Equalizers for audio packages that I
have seen are really only any good for changing the amplitude at general
points along the audio spectrum. The sound of the motor on your camera will
exist at a very narrow spread on the spectrum, and if it is at a frequency
that exactly matches these generalized points you will have great fun
trying to get rid of the noise.

I doubt that you will have a great deal of success with my first mentioned
option, I didn't. which is why I now have two camera cases, one for my two
digital cameras and one for all of the other junk I need. Its all very self
defeating in the end.
