Embedded Lab

With a lot of horse power built in, Raspberry Pi can do a lot of interesting things with audio such as creating artificial sound effects, synthesizing music, etc. PiOSCBOX is a similar low-cost project to build a stand-alone audio effects processor and synthesizer using Raspberry Pi 3 and an external USB sound card. The project features an interactive user interface using a 128×64 graphic LCD and six rotary encoders. The audio processing and synthesizing requires heavy DSP capabilities, which are implemented using Pure Data. Pure Data is an open source visual programming language for musicians and artists to create a software to generate audio/video effects and 2D/3D graphics. It also allows users to interface external sensors and midi devices.
