DTMF (Dual-Tone Multi-Frequency) tones are used in telecommunication signaling. Normal DTMF tones consist of a combination of two specific frequencies for each key pressed, which are typically 697 Hz, 770 Hz, 852 Hz, or 941 Hz for the low frequencies, and 1209 Hz, 1336 Hz, 1477 Hz, or 1633 Hz for the high frequencies. Long DTMF tones, on the other hand, are extended versions of these tones, lasting longer than standard tones, which can enhance detection accuracy in noisy environments or during certain applications. The primary difference lies in their duration and potential application scenarios.
