Room Acoustics
When using multiple microphones, the distance between microphones should be at least 3 times the distance from each microphone to its intended sound source.
What is the 3-to-1 Rule?
The lowest frequency component of a complex waveform such as musical note. It establishes the basic pitch of the note.
What is the Fundamental?
A stereo microphone technique using two identical microphones spaced several feet apart horizontally, usually aiming straight ahead towards the sound source.
What is an AB (Spaced Pair)?
Frequency components above the fundamental of a complex waveform. They are generally multiples of the fundamental which establish the timbre or tone of the note.
What is a Harmonic?
A stereo microphone or two separate microphones, placed so the diaphragms occupy approximately the same point in space. They are angled apart and mounted one directly above the other.
What is XY (Coincident)?
The ability of a device to respond to a rapidly changing input.
What is Transient Response?
A short signal with a rapid attack and decay, such as a drum stroke, cymbal hit, or acoustic guitar pluck.
What is a Transient?
A stereo microphone technique in which directional microphones are angled apart symmetrically on either side of center and spaced a few inches apart horizontally.
DAILY DOUBLE
What is XY (Near-Coincident)?
A thump of explosive breath sound produced when a puff of air from the mouth strikes the microphone diaphragm. Occurs most often with “p”, “t”, and “b” sounds.
What is a Pop/Plosive?
A stationary sound wave that is reinforced by reflection between two parallel surfaces that are spaced a wavelength apart.
What is a Room Mode (Standing Wave)?
A coincident stereo microphone technique that uses a cardioid or omni as the mid microphone aiming straight ahead, with a bidirectional microphone aimed at the sides. The stereo spread is adjustable during playback.
What is M/S (Mid/Side)?
Frequencies that occur between 4k-10kHz that make S and SH sounds harsh.
What is Sibilance?
