The Mamba Digital Snakes are commercial products created by Network Sound, that are used in pairs to replace costly analog cable snakes by a single ethernet cable. A pair of boxes can send and receive up to 64 channels at 48KHz sampling rate packed with 24 bit samples. This paper describes the evolution of jack-mamba, a small jack client that can send and receive UDP packets to/from the box through a network interface and basically transforms it into a high channel count soundcard.
