We have five single channel signals (the instruments directly picked up
with close microphones), which we feed into a 3rd order horizontal
Ambisonics panner. To some extend we can code distance expression by
adding reverberant bits on a virtual stereo source coming from the same
direction as the source (dry/wet ratio and stereo width is distance
depending). All parameters can dynamically change; trajectories of the
virtual sources are designed to match the music.
