Have never used Max, I need just 2, but probably 4 sound source positions and one listening position. But the listening position should have full spherical ambisonic soundfield. But the result should be ambisonic IR's for these 4 sources.
The question is could upsampling be used ? BR Bo-Erik 2018-04-23 10:47 GMT+02:00 Hyunkook Lee <h....@hud.ac.uk>: > Indeed HIRT is the best IR capture package for Max.
