More about this voice

How a can and a string shape a voice

Part	Setting	What you hear
String	Bass cut below 700 Hz, treble cut above 2.5 kHz	Only a sliver of the voice gets through
Ring	Midrange +9 dB around 1.5 kHz	One note of the can sings along with every word
Metal walls	Flanger 0.1 times a second, 50% mix	A hollow, tubular colour that shifts very slowly
Rattle	Distortion drive 0.2, 40% mix	The bottom of the can buzzing on loud sounds

Shout down the string

Speak up, as if the other person is at the far end of a garden. A raised voice has more energy in the band that survives.
Open your vowels wide. Sounds like A and E sit near the 1.5 kHz ring and make the can sing; a mumbled O or U nearly vanishes.
Keep messages short and childlike: a password, a secret, a question that needs a yes or no.
Cup your hands around your mouth while you talk. It changes your real tone in the same direction and adds to the effect.

Tin can, telephone or walkie-talkie?

The telephone voice is a wider band with digital grit: an electrical line. The walkie-talkie adds crackle and overdrive: a radio. The tin can has neither. It is purely acoustic, much narrower than both, and defined by one ringing resonance. That makes it the right pick for childhood scenes, treehouse stories and toy characters. Two variations change the can. With the treble cut lowered to 1.8 kHz the string is longer and less gets through. With the bass cut at 400 Hz and the ring moved down to 900 Hz it becomes a bigger coffee can, lower and boomier.
