#DTMF Sound Detector

By: Zhang Zhe

Run DetectDTMFTones !

##Brief

DetectDTMFTones.m is the main entry of this application.

dtmf_G2 , findSegment, fk2dig are user defined functions of this application.

enframe.m is a function of third party toolbox 'voicebox'. dtmf_sound.wav is audio file of DTMF tones for demonstration.

If you want to detect your own DTMF sound files, you can modify the code：

[x fs] = audioread('dtmf_sound.wav'); 

in line 3 of DetectDTMFTones.m.

##P.S. This project ignore the noise of the DTMF sound files， however as long as the SNR is good(or the noise is not too loud), it still can output correct results.
