Dtmf

Why use an audio spectrum analyzer? For those of you that have done video installations, would you install a camera and lens without a monitor to see what you are doing? Why would you do an audio installation without seeing what you are doing? The analyzer gives you an inexpensive method to...

DTMF detector library and/or application that reads in the specified audio file and returns/outputs whether DTMF detected and/or list of detected digits. May have GUI and command line interfaces.

This is a GUI for DTMF generator-decoder using Goertzel's algorithm.Has options to change Number of samples and Noise power that could be added at the generator.Suggestions and comments is always welcome.Now i am working on medical image pattern recognition techniques.It would be great if...

Unlike all other posted DTMF programs, my application is specifically designed to simulate the working of a real DSP processor especially for beginners.That would mean that digital oscillator was used to create sine and cosine functions and signal is passed through 8 filters. The signal is...


Platforms: Matlab

A program that allows you to detect DTMF tones, generated for example pressing any key of your mobile, as it happens on automated phone service lines.You can record a tone using your microphone (one tone a time); the software will analyze it and detect it. You can also see its FFT.For more...


Platforms: Matlab

Simulink model of a dual-tone multi-frequency (DTMF) generator and receiver. Includes bandpass filter bank receiver, real-time soundcard audio, spectrogram of channel and uses Stateflow block to store decoded digits.NOTE: A version of this model which works with the current release of MATLAB and...


Platforms: Matlab

A phone-like DTMF tool with GUI using several methods, FFT,goertzel and filter banks.Just run the gui.


Platforms: Matlab

Generates dual tones used for DTMF (Dual Tone Multi Frequency) on a touch-tone telephone. Can be used as a signal generator to test the Goertzel Algorithm.Contains a beginners tutorial on how to generate waveforms using Matlab .m files


Platforms: Matlab

The model simply implement a dtmf gererator into a TI C6711 DSK. 3 user switches are used to send different dtmf tone to the line out. To check for the result, one can either connect the line out of the board to the speaker or to a dtmf decoder(e.g.:model in Simulink and feed the signal in...
