App Description

The DTMF app decodes and encodes DTMF (dual-tone multi-frequency) tones htrough the phone's speaker and microphone.
The encoder always assigns two tones to each key. The length of the tone and the pause between them can be set from 35 ms to 1500 ms. Nine macros can be programmed to play phone numbers, ham radio auto patch numbers, amateur radio echolink IDs, and much more.
The decoder detects DTMF tones and prints them on-screen. A sophisticated algorithm detects the tones even in noisy environments.
