Not yet - the disk is on order. However, perhaps I should clarify my earlier post...OK here goes: A speaker - like a microphone - is ultimately a very simple device in its purest form. It is a diaphragm that moves back and forth in a more or less linear fashion. There are only two key relevant variables - how quickly it moves back/forth (frequency) and how far it moves (amplitude). It has no concept of directionality - it cannot steer a sound left/right or up/down - it merely projects sound forward (usually) from its diaphragm in a broadly conical pattern. (Note this doesn't not apply to special cases such as the Soundfield Mics or that clever Yamaha directional speaker array in a box) If one were to place a 2-d array of microphones or SPL transducers in front of a pair of speakers playing the LEDR track, they will record what is actually happening...in other words, as the sound "appears" to us to transit in an arc, in fact it is merely panning left-right, since that is all you can actually do! The mics will not be fooled. The mics will not record a movement in height, because there is none. Our brains are inferring the height element from the psycho-acoustic info embedded in the sound. The reason I want this track is to test what happens if you compress it. Theory suggests that at a certain bitrate, the effect will collapse due to lack of information. Also this could be used as a suitable (albeit non-musical) test track for system end-to-end integrity since the better/more easily a system can reproduce this trick, the better its information preservation capabilities (stress: IN THEORY). Just to restate my position - ignoring the trickery of things like LEDR, it is not possible to accurately reproduce "depth" or "height" (even if it were actually recordable in the first place!) from speakers that are very few in number and fixed in position relative to our ears. What we are hearing is what we want or expect to hear/were genetically engineered to hear. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...SB3+Stontronics PSU - Altmann JISCO/UPCI - TACT RCS 2.2X with Good Vibrations S/W - MF X-DAC V3/X-PSU/X-10 buffer (Audiocomm full mods)- Linn 5103 - Linn Aktiv 5.1 system (6x LK140's, ESPEK/TRIKAN/KATAN/SEIZMIK 10.5), Townsend Supertweeters, Kimber & Chord cables ------------------------------------------------------------------------ Phil Leigh's Profile: http://forums.slimdevices.com/member.php?userid=85 View this thread: http://forums.slimdevices.com/showthread.php?t=42115 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
