More about this voice

The two numbers inside a bitcrusher

Part	Setting	What you hear
Bit depth	6-bit	Loudness moves in 64 coarse steps, which adds a grainy hiss that follows your words
Sample rate	8 kHz	The top of the voice folds back down as a metallic ring on S and T
Mix	100%	No clean voice underneath; all you hear is the crushed signal
Pitch	0 (unchanged)	Your own note, so it still sounds like you
Filters	Bass cut below 180 Hz, treble cut above 9 kHz	Rumble and fizz trimmed off both ends

Speaking into a crusher

Keep your volume even. Quiet syllables land on only a few of the 64 steps and break up into noise before loud ones do.
Lean on S, T and CH if you want the ring. Soften them if the ringing gets tiring.
Let word endings fade naturally. The crusher turns a fading vowel into a crumbling tail, which is the best part of the effect.
Hold a steady distance from the mic; moving in and out changes how much grit you get.

Which crush to pick

The main clip is the middle ground: clearly digital, every word readable. The 4-bit clip leaves only sixteen volume steps, so the voice turns harsh and noisy and quiet words drop out. Keep that one for short stingers and sound design. The 12-bit clip at 4 kHz goes the other way: the steps are smooth, but the very low sample rate makes the voice dull and ringing, like a toy's sound chip. Use it when you want the voice to sound cheap rather than broken.

The exact settings

Setting	Value
Noise gate	mutes the mic below -50 dB, between words
Pitch	0 (unchanged)
Bit crusher	6-bit at 8 kHz, 100% mix
Bass cut	below 180 Hz
Treble cut	above 9 kHz
Compressor	steadier volume (6:1 from -26 dB, then +3 dB)

What's the difference between this and the 8-Bit voice?

The 8-Bit voice also raises pitch and clips the sound to imitate an old game console. This page is only the crusher, at Pitch 0, so you can hear what bit depth and sample rate do by themselves.
