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.
A benchmark for Goertzel algorithm and `scipy.fftpack.fft` (with custom implementation of Goertzel algorithm in short-time version) **for evaluating a few DFT terms**
An implementation of the Goertzel Algorithm for Audio Processing in Java and example DTMF Generator and Decoder with user interface to show what goes on under the hood.
In this repository I store example scripts of some DSP algorithms made in MATLAB. These served an educational purpose when I wrote them, I'm making them public, since I had trouble finding example code.
