Before and after

Setting	Value
Noise gate	mutes the mic below -55 dB, between words
Pitch	+3 (higher)
Tone	+1.5 (sounds smaller)
Chorus / vibrato	wobbles 5.5 times a second, 100% mix
Bass cut	below 200 Hz
Treble cut	above 6.5 kHz
Midrange	+2 dB around 1.8 kHz

A wobble: a fast, shallow vibrato (5.5 times a second) like the slight unsteadiness of an older voice.
Less body: bass below 200 Hz and treble above 6.5 kHz are cut, so the voice is thinner.
A forward middle: a small boost at 1.8 kHz, the slightly reedy quality of age.

The old man voice has all three. The old lady voice keeps them and moves the pitch and tone up, so a lower voice ends up in an older woman's range.

Clip	Change	Character
As it is	Pitch +3, tremble on	A sweet, slightly shaky grandmother
Steady	Tremble off	A brisk, sharp older lady
Frailer	Pitch +5	Very old, high and thin

Lower Pitch to +1 or 0. The tremble and thin band make it sound older without pushing the note too high.

Yes. Record in the Online Voice Changer, pick Old Man, set Pitch +3 and Tone +1.5, and download the WAV.

The old lady voice is built from it. Reset brings back the plain Old Man preset.
