I experimented with the sound for "My Most Difficult Case" this week. I was unsure just
what to do with the sound and needed to get a better idea of my options.
There are two issues I want to address with the sound.
The first is that I find the voices sound weak to me. I
think that may have been a result of the noise reduction I did. I tried a few
things to process the sound to see if I could give the voices more body.
The other is the lack of environmental sound. There is no
real background sound and there are several places where I think sound effects
are needed. An example is when the prosecutor picks up some books and there is
no sound. I left this until later.
I use Audacity for my audio work. I'm not sure how it
compares to other audio programs, but the price (free) is right. It seems to
have all the capabilities that I need.
Compression
My first test was to try out sound compression. Compression
reduces the volume of the peaks while leaving the rest of the sound the same. I
found this allows me to turn up the volume of the voices, which makes them
sound stronger. I tried several different settings, but I couldn't tell the
difference, so I just used the default settings.
The compression did increase the background noise, which
hadn't been apparent before. The additional noise wasn't acceptable, so I reran
the noise reduction and brought it under control, without a noticeable change
in the voice quality.
Reverb
I've always though of reverb as something different from
echo, but that didn't seem to be the case. I tried some different settings, but
didn't learn much from that.
Then I found that the reverb effect had some presets for
different types of rooms, such as big room, small room, bright room and dark
room. I found that the big room and bright room settings made the voices sound
weaker. That was the opposite of what I wanted. The small, dark room setting
seemed to give more body to the voices.
Next Steps
To my ear, the combination of the effects I tested does
bring me closer to the quality of sound I want. However, the effect isn't as
strong as I'd like it to be. I want to see if there is anything else I can try.
My copy of Audacity has something like 140 effects, and my copy of Premiere Pro
(CS4) has about 80 audio effects. Apparently you can get more if you want them.
I'm familiar with maybe a half dozen or so, but I have no idea what most of the
rest do.
I'll need to do some more research. I could use some advice.
