DTMF Dialer is an application that generates telephone keypad tones using Dual-Tone Multi-Frequency (DTMF) signaling. On a standard phone keypad, each row and column correspond to a specific frequency. When a key is pressed, the two associated tones are played simultaneously. The audio produced by this app can be used for dialing phone numbers and navigating phone system menus.
This app is a semi-AI-generated recreation of an old demo from
WaveFile.js. Years ago, before browsers supported the Web Audio API, WaveFile.js was developed as a way to create audio files programmatically using JavaScript. This version leverages the Web Audio API for improved performance and functionality.
