For anyone who produces fandubs and radioplays, you've probably noticed how everyone has VERY different mic qualities, and it can make your production lack a uniform and/or professional feel. Since I started experimenting with filters and compression many have asked for advice on how to do it, so I decided it would be easier to make a topic with screenshots explaining. ^^ This is for Adobe Audition users. Unfortunately, you don't really have this option in Audacity. I can't say for sure on Goldwave since I haven't used it.

First off, do your basic mixing and volume leveling---sound effects, music, and voices. The compressor will fix some of the volume equalization, but it won't do miracles, so try to get everyone's volumes as close to each other as possible. If anyone's lines are fuzzy, you may wish to do some noise reduction as well because filters can amplify static. When you're finished, your window in Multitrack will look something like this:

Now, go to File-->Export-->Audio Mixdown. After you save, your mixed file should automatically appear in the Edit window:

Select the entire file, then go to Effects-->Amplitude-->Multiband Compressor. A window like this will appear:

Play around with the slider bars and keep previewing til you bring out what you like in the sound. Make sure the audio doesn't peak---if it does, lower the "gain" slider until you don't see any red in the meters. The above is the custom setting I used for my latest fandub, so if you'd like, you can start with that and then adjust as needed to fit your production.

When you're done, save your file. If it's a radioplay...you're done! If it's a fandub, just use that as the audio track and merge it with the video using the program of your choice. Overall, you will find that this gives your final mix a much more professional sound.

Great tip!!! Multiband compressor is very useful. Especially for sound balancing.

Also, I think if you go down to the Master Track, right click, and choose EQ rack, you can can add the multiband compressor as an effect to the Master Track. Might be a bit faster than exporting the audio downmix everytime you make some changes. I don't have Audition on this comp anymore so I could be wrong.

yay, it looks spiffy.

I didn't know you could do that (most of adobe's options are too complicated for me to read lol) so I just do it by hand..
Need to try this sometime .. ^^ thanks for the tip!

D: Why didn't I think of that sooner?!

It seems like it'd work---I'll try it for my next project :3

Good tip! I've been using Adobe Audition for over a year now, and I'm still learning new things about it every week it seems! :sweat The best ways to learn the program are to experiment and share tips with fellow users!

Edit: I tried your settings above, and found they did change the sound a lot, although in the scenes I used them on I found they tended to make the clips sound more different, not less. They really brought up the static and original background reverb of the clips I was working with, so definitely not working for me. However, I did find the "Bring Up Vocals" compression setting that comes with Audition did a nice job of smoothing the sound, so to each his or her own. :) It's still a good tool to get more familiar with!


Thanks again!
