I agree. Time confusion in stereo(as generated by spaced omnis) is far from being the same thing as spatially diffuse field sound. This is the real reason stereo sounds wrong as far as I am concerned. No offense to people who like "spatial music" but the music I like happens in front. What does n

for me, this is where ambisonics (or surround sound) really comes in. we have been recording dry (even with blumlein) and hoping the speakers at home will create enough 'ambience' of some kind. one reason we are forced to do this is because in the real world reverberation is three dimensional;

It is interesting how this more or less obvious point- that localizing discrete sources and localizing all the(often multiple( reflections that make up the whole spatial impression would be one supposes related--has escapted the popular press especially of the "High End" ilk. They are all wound

One thing that just occurred to me, given the fact that this is related to a piece of Stockhausen's, is, maybe it's worth looking at Stockhausen's writings in the original German from around this period - could be just a (slightly strange) translation of something he wrote... Dave On 18 Apri

Hi I am not sure if this is at all related to the same subject that you are discussing, but someone sometimes taught me how to reduce the spotness of a single mono source when panned into the surround soundfield. This is a problem when you do a surround mix from mono tracks, the space avalibale

I wonder if it's not simply a matter of a stereo spread control as one would get with an stereo to MS to stereo conversion, where in the MS state, one can vary the width of the stereo signal. If we don't assume that someone tries to spread a mono signal, but has a stereo signal and is simply pl

actually, to control "image size" (apparent source width), one must control the interaural cross correlation rather finely, which in practice means controlling (or varying) inter-channel cross correlation (though with surround sound - ambisonic or otherwise, one actually has to control more spea
