Concept-dsp

•    C

This program is intended as an educational tool to explain the concept of Discrete Fourier Transform (DFT). It uses the Fast Fourier Transform to calculate the DFT of a given arbitrary time domain signal and plots it graphically.

Bauer stereophonic-to-binaural DSP

•    C++

The Bauer stereophonic-to-binaural DSP (bs2b) library and plugins is designed to improve headphone listening of stereo audio records. Recommended for headphone prolonged listening to disable superstereo fatigue without essential distortions.

Cross Time DSP

Cross Time DSP implements conventional forward time IIR processing of music files as well as time reversed IIR. This allows linear phase via inverse allpass or other inverse filters in addition to standard equalization. Unlike other time reversed IIR implementations, it's fr...

uCOS-II and lwIP on TI C6000 DSP

•    C

Port lwIP and uC/OS-II on a TI C6000 DSP platform. The 10/100M ethernet was based on a DaughterCard designed by ourselves. And it has been tested on TI C6711 DSK amp; C6713 DSK. The schematic files of the daughtercard is also part of this project.

Signal Processing using C++

•    C++

The objective of SPUC is to provide the Digital Communications Systems Designer or DSP Algorithm designer with simple, efficient and reusable DSP building block objects written in C++.

SonicBirth

•    Objective-C

SonicBirth is a modular audio and music development program which allows you to create DSP structures (SonicBirth circuits) graphically, by wiring DSP elements together. It lets you build new effects and musical devices, and then export them as plugins.

IAXmodem

•    C

IAXmodem is a software modem written in C that uses an IAX channel (commonly provided by an Asterisk PBX system) instead of a traditional phone line and uses a DSP library instead of DSP hardware chipsets.

Haskell DSP Libraries

The project is an implementation of DSP and related algorithms in the programming language Haskell.

muchfx

•    C

muchfx is a continuation of the MuchFX? DSP stacker for winamp by Ressl which allows you to use multiple DSP effects simultaneously with winamp 2. It will support skinning, better plugin support.

NVDSP - iOS/OSX DSP for audio (with Novocaine)

•    Objective-C

Implement high quality audio filters with just a few lines of code and Novocaine, or your own audio library of choice. To start out I recommend you to get a fresh copy of Novocaine and open Novocaine's excellent example project. Then import NVDSP and the Filters folder and start your filtering journey.

ThinkDSP - Think DSP: Digital Signal Processing in Python, by Allen B. Downey.

•    Jupyter

LaTeX source and Python code for Think DSP: Digital Signal Processing in Python, by Allen B. Downey. The premise of this book (and the other books in the Think X series) is that if you know how to program, you can use that skill to learn other things. I am writing this book because I think the conventional approach to digital signal processing is backward: most books (and the classes that use them) present the material bottom-up, starting with mathematical abstractions like phasors.
