>> except its not quite the same effect. If I hear a plan(ish) wave in nature such as in thunder or a very distant giant waterfall
Distant thunder is often an extreme case of Proximity effect. Velocity components are boosted at LF compared omni components. You encounter this if you are using TetraMic or properly aligned Soundield and there is a distant thunderstorm. Sometimes you will see XYZ, the Velocity Components go wild when nothing is happening on W, the Omni bit. Usually you can't hear anything either but can time the 'happenings' many seconds after the lightning. This is in spite of built in 24dB/8ve electrical filtering and effectively 36dB/8ve acoustic HP filtering. On TetraMic, the variable HP filter is usually good to get rid of this effect. _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound
