More about this voice

Why phones sound like phones

A traditional phone call only carries roughly 300 to 3,400 Hz. That's enough to understand words, but it drops the chest of a voice and the air on top. The preset cuts the same band, then samples the result at 8 kHz with 8 bits, which is where the slight grain comes from. A small mid boost at 1.8 kHz adds the honk of a handset speaker.
