MULTIBAND HARMONIC EXCITER
Let’s start with a Multiband Harmonic Exciter as our first venture in Ozone multiband
processing. It’s an easy effect to hear, and is very powerful when used as a multiband effect.
processing. It’s an easy effect to hear, and is very powerful when used as a multiband effect.
Before we get started with the Multiband Harmonic Exciter in Ozone, though, here’s a little
background on the principle of exciters.
An exciter is typically used to add a sparkle or presence to a mix. It’s a sound heard on many
pop recordings, and was probably used to an extreme on pop in the 80s, but is still commonly
heard today. A beginner might try to get the same “sound” as an exciter with high frequency
EQ boost, but with less than similar results.
EQ boost, but with less than similar results.
There are many design strategies used in the exciters commercially available today, from
waveshaping and distortion to short multiband delays. Distortion in small doses isn’t
waveshaping and distortion to short multiband delays. Distortion in small doses isn’t
necessarily a bad thing. If designed correctly and applied with restraint, distortion can create
harmonics that add an excitement or sparkle to the mix.
Ozone provides a selection of exciters modeled on analog tube or tape saturation. When tubes
saturate, they exhibit a type of harmonic distortion that is surprisingly musical. This distortion
creates additional harmonics that add presence or sparkle to the mix while still preserving a
natural analog characteristic. You can see perhaps why boosting high frequency EQ is not
natural analog characteristic. You can see perhaps why boosting high frequency EQ is not
going to achieve the same effect. Boosting an EQ simply turns up the existing harmonics,
where a harmonic exciter actually creates additional harmonics. Tape saturation provides a
similar effect, although the harmonics that are created are more “odd than even”. That is,
similar effect, although the harmonics that are created are more “odd than even”. That is,
tube saturation typically generates even harmonics that are an octave apart (again,
musical….), while tape saturation is a slightly more aggressive excitation that generates odd
harmonics that are a fifth apart.
It’s also very easy to overdo an exciter. What may sound good at 3.0…might sound even a
little better at 4.0…and once you get used to that you find yourself pushing it up to 5.0 to
keep the “excitement”. Before you get caught up in the excitement (pun intended we guess)
keep the “excitement”. Before you get caught up in the excitement (pun intended we guess)
and send it off the duplicator, do a little reality check:
1) Compare it to some commercial mixes. OK, in some cases these are overdone as well, but
it depends on the genre and sound you’re shooting for. What works for a dance mix probably
isn’t going to sound as appropriate on an acoustic jazz number.
2) Live with the “excited” mix for a while. At first listen an exciter is, well, exciting, but over
time it can really sound fatiguing or even harsh and annoying.
Using the Multiband Harmonic Exciter in Ozone
This is a very easy effect to use. That could also be why it’s often overused.
Each of the four bands has a pair of controls. In most cases, you’re going to be using the
Amount control. In addition, you’re probably going to be applying excitation to the upper one
or two bands, although there are some cases where tube saturation in small amounts across
or two bands, although there are some cases where tube saturation in small amounts across
the entire spectrum (all four bands) can be musically pleasing.
With your mix playing (of course) adjust the Amt slider in Band 3 upwards. As you move the
slider up you’ll hear what starts as sparkle and excitement, but can quickly turn against you as
slider up you’ll hear what starts as sparkle and excitement, but can quickly turn against you as
you go up too far. Take note of the point where it starts sounding “annoying” and then turn it
back down to 0.0.
Now try moving up the Amt slider for Band 4. Chances are, you’re going to be able to tolerate
