Hi Steve, An interesting proposal. You'll excuse perhaps my misunderstanding here, but my understanding was that ambisonics A format consists of a omni plus x,y,z to give 4 signals that are then converted to b format . I built my own ambisonics mic and decoder once a long time ago so perhaps things have changed, I think I put Left + & - right = x Front + & - Back = y Top + & - bottom = z All summed * 0.257 = w into my decoder. . Anyway I digress - this basically will give you a sounds position in 3D space , or at least on the surface of a sphere proximity not being so well recreated. So if you had say, 8 ambisonics mics pointed in 8 different directions ,in order to record that small 8th of a sphere (or in this case cube) in the direction they are pointed in (which is what the ORTF does) - how would this work if the decoder if a format gives spherical coordinates rather than an 8th of a sphere/cube (hope this makes sense), and with the capsules pointing in all directions... ? cheers Gus
