Here is the page for the plugin: http://www.waves.com/Content.aspx?id=327

I can't figure out how to do this. I thought that maybe I could use a presencefilter and replicator to create the harmonics and scale the base frequency, but PresenceFilter doesn't accept variables in the CenterFrequency nor BoostOrCut fields. I set the Bandwidth to 1 nn.

Is there, perhaps, a smalltalk expression or script I could use to achieve this?

Typically, the missing fundamental effect occurs when you have strong harmonics 2, 3, & 4. So one thing to try would be the Kyma Sound Library/Effects Processing / Distortion / Waveshape by Polynomial and LPF. Try setting c1 through c4 to 1, and the other c controls to 0. Then set the LPF to 128 hz.

From the names on the controls, it sounds like it may also be compressing a low-pass-filtered version of the input. So you could try taking the waveshaper output and feeding it to Compressor dB from the Prototypes. Then use a Crossfade to get a blend between the dry input and the distorted, low-pass-filtered, compressed version.

I tried your suggestion, Carla, but I'm still not sure if what I'm hearing is just the effects of filtering & compression, or the actual 'missing fundamental.'

Another approach was to synthesize a 60hz sine wave with harmonics that roll off in amplitude as they go up, while the amplitude envelope is driven by the signal being 'enhanced.' The problem with this is that it simply sounds too different and artificial. Smoothing and tweaking the ADSR helps a little, but it creates a harmonic tone instead of inharmonic energy.

Any suggestions to how I can achieve this missing fundamental without making it so tonal? If it's based on harmonics, do they need to shift in frequency? Maybe tracking the frequency of the signal, using that to create a subharmonic fundamental, then use scalable harmonics from that, driven by the dry signal's amplitude?

Also, for the compression, I added David McClain's "Hands-Free Compressor." Very nice.

It may be based on the octave divider that introduces an additional sub octave as talked about in the link below.

To make this you would need a JK type flip flop working at sample rate but I don't know how you would do this in Kyma.

If you have a Capybara you could use the toggle module in Pete's DSP modules to do the job.

Hope this makes sense

Yes, I see that they are trying to make higher freqs sound like of bass for systems that don't have so much, as apposed to generating bass that wasn't there to fill up the space in systems that do.
