Top Ten Must-Have Audio Effects for Audio Post, Part Two
Here are five more must-have plug-ins that I rely on for my audio-post work.
Compressor(s)
Dealing with dynamics is as important as handling the tonal aspects of sound (using EQ). And just like EQ, I like my compressors to sometimes just work and not get in the way and other times to really have a sound that provides some new color. Standard compressors are a dime a dozen, and I have several. But for color, I rely on the LA-2A and Fairchild software emulations from Universal Audio. I also like the 88RS channel strip. On DM&E (and other major) busses, I often resort to iZotope Ozone4′s multiband and this plug-in sometimes ends up on the stereo bus, too (with a touch of compression, loudness maximizer, and just-in-case limiter).
Reverb with early reflections
Location sound recordists often use a lot of close miking on performers to get cleaner dialogue (thank you!). However, this can sound a bit dry in the mix or not fit the camera’s perspective. Reverb is the tool of choice to add back in the missing ambience and give some air to the words. However, while simulating parking garages and auditoriums is relatively easy, it’s the subtle reverb effects that are infinitely more valuable. For creating good room sounds, a reverb plug-in that offers a lot of control is what’s needed. I like the freeware Ambience program along with a good convolution-based reverb using plenty of impulse responses (I’ve collected over the years).
Stereo widener
There has to be room for the dialog, so moving music, sound effects, and especially background ambiences out and away from the center is useful. A stereo widener is the key, and I use the one in iZotope Ozone 4 for my work. You have to be careful with these, though, and make sure any widening you do is mono compatible. You don’t want part of your soundtrack sounding funny or going missing altogether if your work gets played in mono (or through out-of-phase speakers). Always check the mono compatibility of your work. Always. One of my favorite stereo widening tricks is … well … the subject of another post!
Limiter
I use a limiter for some dynamics control in interesting ways such as limiting a duplicate of a sound very hard and mixing that back in with the unlimited version (great on percussive sounds). I also use a limiter on the master bus to catch overs. I don’t hit it hard, just a bit to tame the errant slight peak. It’s also useful for limiting dynamic range for alternate delivery (e.g. web) without having to totally remix a theatrical/DVD soundtrack.
Noise Reduction
Another desert island tool that you can’t seriously work in audio-post without. There is really only one choice: iZotope RX Advanced. Period. Read about it here.
That wraps up this two-part article on my go-to plug-ins for audio post. So now, what plug-ins do YOU rely on for your work?

Jeffrey: I notice you imply that you can use Ozone on some individual channels plus on the stereo buss. Any more than one instantiation of Ozone usually pushes me over the edge of buffer overruns in PT8. Izotope tech support recommended that I never use more than one instance of Ozone per project (usually only on the stereo buss) because it is such a processor-hog. Is your experience different? I’m trying to figure out if I have been using plugs incorrectly, or if I have a computer problem, because I run into buffer overruns far too often for my happiness. (Oh, wait, are you host-based or HD?) Even though I have intermittent problems with Ozone, I agree that it is one of the best tools — and one that gets used on almost every single project that comes through my shop.
I took a good listen to Alloy and RX at NAMM this year, and really like both of those. I think they will be in my arsenal soon…
I have in the past run Ozone on a track or two or more likely a bus or two. Today I mostly use Alloy on tracks, but still use Ozone on a couple of busses (usually BGs for the stereo widener). Here’s the critical part: I use Acid/Vegas Pro and it handles the load better especially on my newer machine. Sometimes I disable an effect if it hogs too much and then enable it for the render! I can run a lot of effects for the render with no issues.
Ah, Acid/Vegas. I love PT8, but sometimes I wonder if I’m working on the wrong system. Thanks for the response! (I think I’m going to stick with PT, but Alloy is going to have to join my toolbox, to take some pressure off the system.)
