The difference in 'time' is what gives us STEREO PERCEPTION. Look at the space between your two ears, and I'm NOT saying the empty space ;-). It's the phase relationship between the left and right ear and the timing/phase difference that allows you to 'place' a sound you hear with your eyes closed. The same holds true in multi-microphone recording techniques. Your example of a 20Hz wavelength being recorded to two mics 30-feet apart is not really valid, unless you're recording Bach's Concerto for Solo 20Hz Oscillator.... music is multi-frequency with varied frequencies/wavelengths happening all the time. IMHO, there is no possible way to have absolute phase coherency at all frequencies at all times in an acoustic recording environment. Actually, if you could, it would probably sound lifeless and sterile because our ears and brain don't work that way. Many studio reference monitor manufacturers have incorporated phase coherency into their monitors, but it's usually done by placing the voice-coil of each individual driver in the same physical plane, allowing the combined sound to leave the 'box' as a phase aligned source. What happens in the room before it hits your ears is part of the ear/brain/ experience that can't be compensated for UNLESS the music was recorded, mixed and listened to in an anechoic chamber. Doesn't sound very exciting to me. -- Eric Seaberg Eric Seaberg - San Diego [EMAIL PROTECTED] ------------------------------------------------------------------------ Eric Seaberg's Profile: http://forums.slimdevices.com/member.php?userid=7896 View this thread: http://forums.slimdevices.com/showthread.php?t=35708 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
