This site hosts designs for a flexible and modular free open source hardware audio DSP (digital signal processing) platform.
For the latest updates see the news section below and my blog.
The open hardware DSP platform is a range of small boards that can be plugged together to give you a flexible platform for processing all sorts of audio signals. If you want a simple crossover, a custom USB soundcard and headphone amp, or a fully fledged 48 channel mixer or synthesizer there should, eventually, be something here to do it. All board designs and information are released under the TAPR Open Hardware License.
Work is on-going on this project and hardware is still being tested and proven. Eventually with the board designs and details I will host some example projects. These will include downloadable example project files for SigmaStudio to allow you to get going once boards are plugged together. If enough interest grows in the project I would like to offer boards for sale potentially through group buys to start with.
