DTMF decodes and encodes DTMF (Dual-tone multi-frequency) tones trough the phones speaker and microphone.
Encoder: Always 2 tones are assigned to each key.The length of the tone and the pause between the tones can be set from 35ms to 1500ms.
A total of 36 marco’s can be used to play phone numbers, ham radio auto patch numbers, amateur radio echolink id’s any many more.The 36 macro’s can be saved to the phones/tablets memory. This way a unlimited amount of macros can be used. The DTMF tone length and the pause between the tones can be adjusted.
Decoder: The decoder detects the DTMF tones and prints them on the screen. A sophisticated algorithm detects the tones even in noisy environments.
