Generate authentic DTMF dial tones for phone numbers and digit sequences. Create precise dual-tone multi-frequency signals used in telephone systems worldwide.
What are DTMF Tones?
DTMF (Dual-Tone Multi-Frequency) signals are the beeps you hear when pressing phone keys. Each key combines two pure sine wave tones - one from a row frequency (697-941 Hz) and one from a column frequency (1209-1633 Hz). This dual-tone system was invented by AT&T and has been the global standard since the 1960s.

Frequently Asked Questions
What is DTMF?
DTMF (Dual-Tone Multi-Frequency) is the signaling system used by touch-tone telephones. Each key generates two simultaneous tones - one from a high-frequency group and one from a low-frequency group.
What are the A, B, C, D keys?
The DTMF standard includes four additional keys (A, B, C, D) that were part of the original specification for special functions. While not on consumer phones, they are used in military and some commercial applications.
Why are two tones used per digit?
Using two tones from different frequency groups makes DTMF highly resistant to false triggering by speech or other sounds, ensuring reliable digit detection.
Can I use these for phone automation?
DTMF tones can interact with phone systems (IVR, voicemail). However, timing and audio quality must match system requirements. Test with your specific application.
