Decoder for DTMF (and other MF signals) in Python

A simple frequency to number converter that I made for a CTF

A hack initially for Moderskeppet Gaming geek cruise, I managed to drive a telephone off a 9V battery and pick up the keypad tones as input to act as an Amiga joystick, allowing the TV classic Hugo game to be played as in the good old days. Project diary and cleanup to come.

BlueBox – DTMF Tone Synthesizer & Recognizer

Introduction to creating DTMF key signals, and structures to decode such signals by designing and using simple bandpass filters

Midterm Performance Task in CPE416: Digital Signal Processing

Extract phone numbers from an audio recording of the dial tones.

DTMF - simple DTMF detector and visualizer using Matlab

Decode DTMF audio in go.

This was my BTech degree Mini-Project during semester 5 and it is an electronic lock which can be unlocked from anywhere.

My personal collection of useful Arduino sketches

A web based DTMF encoder/decoder.

🚨 decoding and synthesizing DTMF signals. Processes a given signal and returns a list of decoded keys and the frequencies found in the signal and generates a DTMF signal from a given phone number.

The goal of this project is to develop a DTMF synthesizer function using MATLAB software

C# implementation of the Goertzel algorithm for DTMF tone (a.k.a. Touch-Tone) detection and localization in audio data. Includes wrappers and extensions for NAudio.

Decode the phone numbers from its voice with signal processing

Dual-tone multi-frequency (DTMF) generation and detection based on Goertzel algorithm

This is my Signal Processing lab that developed a Matlab model used to detect the dial tone and decode Dual Tone Multi Frequency (DTMF) signals.

DTMF decoder in Matlab implementing Goertzel's algorithm
