Max/MSP is a graphical programming tool for creating music, sound, video and interactive graphics applications. YouTube user Tom Zicarelli has recently posted a video showing his test of a Max wrapper for rtl_fm, allowing an FM audio stream to be received and controlled in Max. Tom is also working on an RTL-SDR wrapper for PureData, another visual programming language aimed at artists. These wrappers will be useful for artists who wish to utilize RF in their projects.
