Verify of relative distance to sound source for equal balance between direct and indirect sound.

An outline of comparison

To verify of relative distance to sound source for equal balance between direct and indirect sound in the grand piano recording.
In a experiment recording at the Hekinan Emerald Hall and Nagoya University of Arts Hall May, 2014.
The Directional microphone DPA4011 = 4.7m from the Instrument,
he Omnidirectional microphone DPA4006 = 3.1m from the Instrument.
The distance ratio was 1 : 1.5 (65%).
Recorded by RME Micstasy, Magix Sequoia 44.1kHz 24bit.
