The 3:1 Rule works because of the level of the signal entering the second mic the one farther away is a reduced signal than the first mic is taking. Most sound engineers believe that the 3:1 rule for recording will minimize phase cancellation, technically this is not true. When using two mics it is important to always observe the 3:1 rule: Keep your mics at least three times farther from one another than each is from the piano strings (the sound source).Condenser Cardioid Polar Pattern microphones are ideal for recording wide frequencies of the piano Position two tube condenser microphones approximately 11 inches above the strings,1-2 ft.Positioning the mic inside the Piano can isolate the sound and cut the room out or other players from bleeding into the recording.Piano Recording Studio #1 Technique-Mike Placement on the Inside of a Piano Using Closed Miking-Spaced Pair (A-B) Miking & the Popular X/Y Mic Technique The king of instruments when played hits a wide variety of frequencies that can become a complicated effort to capture but there are simple mic placement techniques that try.
X/Y Method-2 Omni Mics-just past Hammers-6″ to 9″ off strings-18″ to 27″ apart.1 Mic aimed to treble strings-1 to bass strings.AB Method-2 Small diaphragm tube condenser mics 11″ above strings, aiming down or.Sonically it truly is the master of instruments and capturing the frequencies when recording a Grand Piano is a detailed art form using different techniques. With over 7,000 parts in a Grand Piano, no other acoustic instrument can compete with it.
