DTMF Tone Extractor

DTMF Tone Extractor


ToneExtractor can decode DTMF (dual-tone, multi-frequency) signals back to numbers

The following are the frequencies used for the DTMF system, which is also referred to as tone dialling. The signal is encoded as a pair of sinusoidal (sine wave) tones which are mixed with each other. DTMF is used by most PSTN (public switched telephone networks) systems for number dialling, and is also used for voice-response systems such as telephone banking and sometimes over private radio networks to provide signalling and transferring of small amounts of data.

didn't work for me i have some speed dial numbers on my deskphone, but could not remember what they are, so I tried to use it to "listen" to the dtmf and tell me the phone number. But it failed. it could hear the tones, because i saw bars, but it could not tell me any numbers.

Possible Galaxy S5 compatibility issue. Does not work on Galaxy S5 SM-G900P. Doesn't appear to be doing anything when I hit aquire, but does work on friend's Galaxy SII.
