I recently made some soundfield mic fieldrecordings of the sea and like to use these recordings in Renoise, but that is impossible at the moment .
I don’t know how difficult this is to implement, but a soundfield b-format.wav consists out of a four-channel signal encoded in 1 file. Three of the signals, the X, Y and Z channels, describe the space around the microphone in the X (Front/Back), Y (Left/Right) and Z (Up/Down) dimensions, and are equivalent to recordings made with three figure-of-eight microphones at right angles to each other. The fourth channel, known as W, is equivalent to a recording made with an omnidirectional microphone, and provides a reference for the three other channels.(quoted from: http://www.soundfield.com/soundfield/soundfield.php )
