Typer

In this mode, pressing multiple keys at once allows you to play their tones simultaneously. Make some music!

DTMF Auto-Player: enter a sequence of keys below and press Play to generate the tones.

DTMF Recorder: record & play back keypresses. (Beta! Do not switch to another tab when recording or playing — the recorder will become unusable)

DT-what?

Dual-Tone Multi-Frequency (DTMF) signaling, a system of transferring data over phone lines. When you hear "Press 6 to talk to a support agent", you press the 6 key, and it plays the DTMF tones for 6, so the system knows what you pressed. Read more here.
