DialABC lets you find DTMF tones within audio clips. All you have to do is to upload an audio file to the dialabc web site using the form below. Our software then analyzes the audio recording and presents you with some statistics, a graph and a table showing you what DTMF tones are contained in the data and where.

All you need is an short audio sample in one of several standard audio data file formats.
