How to create a Wobble Bass with vowel filter

A simple tutorial showing how to create a dub-step style wobble bass with a formant filter type talk effect in ES2

‘Wobble Bass’ as it is known is simply a bassline that has an LFO assigned to a Low Pass Filter as an insert effect. LFO stands for ‘Low Frequency Oscillator’ and is used to change a sound by a defined speed (measured in either Hz or synced to the Tempo in relation to the bars/notes through quantization.)
The way the LFO changes the sound is up to you, you can make the LFO adjust the Volume, the amount of Saturation, Filter Cutoff etc.
Basically any parameter you link it to. Essentially you are just using the LFO to send a changing value to a parameter.

A quick breakdown of what’s actually going on. Essentially you are taking a sound (that can be an audio files, generated by a synth, etc) and then passing it through a Low Pass Filter. A Low Pass Filter allows Low Frequency signals to pass through it, but reduces the amplitude (volume) of all the Frequencies above the cutoff point. In general most plug-ins have various Low Pass Filter settings, where the more poles it has the more Dbs it will cut and will yield a harder knee to it. Example: 1 Pole Filter with a -6dB/Oct reduction Vs a 2 Pole Filter reducing -12Db/Oct.
However, you don’t necessarily need a LFO controlling your Low Pass Filter Cutoff frequency value, you could just draw in the Automation yourself, but a LFO will yield a loop of consistent values and prevents the possibility of human error. All the LFO is doing is sending a value to your frequency cutoff to keep it consistently changing.
