Richard Lee:
I find it much easier to identify UHJ with natural recordings
By this, do you mean recordings that you _know_ in beforehand?
If I gave you 5-7 recordings, would you be able to pick up the UHJ encoded
recordings from them? Some of my examples would include audibly and
measureably similar phase differences between the stereo channels as you
would have in a UHJ recording.
a single properly aligned tetrahedral mike; especially if there
is a nice acoustic.
I would say exactly the opposite. In anechoic acoustics a tetrahedral
mike provides
a very sharp sound image for a single sound source in a certain direction ,
but any reflections and reverberation smear the sharpness. The acoustic
phase
differences add to the signal. When you look at the goniometer you cannot
be sure which phase difference is acoustic and which is caused by the
encoding.
the 2 questions
1 Is it Ambisonic? ie 45J or UHJ (35J)
2 Is it 45J or is it UHJ(35J)?
Oh yeah, that. I leave that to the other guys in here. I find it hard
enough just to
find out if a recording is UHJ at all or just "normal" stereo.
