Mics
This is a microphone that can be placed discretely on someone’s person due to its small size.
What is a Lavalier mic?
The fundamental building block of all sound.
What is a sine wave?
This is what ADSR stands for.
What is Attack, Decay, Sustain, Release?
This can be more desirable because it mitigates off axis sound, making a microphone more sensitive to directionality.
What is side rejection?
This is what ADC stands for
What is Analog to Digital Converter?
An apparatus that includes a diaphragm that responds to sound pressure, which is in turn connected to a coil that is housed inside a magnetic field can be found in this mic.
What is a Dynamic mic?
The height (as a wave is represented on a graph) of the peaks and troughs of a waveform that correlate with volume.
What is Amplitude?
A value employed when measuring the power of a given sound.
What are decibels?
This will generally lead to some loss of SPL.
What is Off Axis Placement?
This is what DAC stands for
What is a Digital to Analog Converter?
This mic utilizes Capacitance to induce a current of electricity that is analogous to an acoustical waveform.
What is a Condenser mic?
The amount of times per second that a sound wave cycles (measured in Hertz).
What is Frequency?
The specific segments of a longitudinal wave, at which the particles are crowded together.
In a very wide shot where there are no obstructions and a very clean mise-en-scene, the use of these mics might be advised because There’s no way to get close to the actor with a boom and nowhere to hide a mic, resulting in a distant sound if relying on a distant boom
What are Lavalier mics?
This does the job of converting an analog signal into digital data by means of sampling, for storage and usage at a later time.
What is ADC?
This mic contains a thin and fragile leaf of metal housed in a magnetic field, utilizes Electromagnetic Induction to induce a current of electricity that is analogous to an acoustical waveform.
What is a Ribbon Mic?
This has an inverse correlation to frequency and describes the distance between two peaks of a waveform.
What is wavelength?
The specific segments of a longitudinal wave, at which the particles are spread out and far apart.
What is Rarefaction?
These refer to the way a microphone can reproduce the sound it’s picking up; either by coloring it or by recreating it as closely as possible to the original sound
What is Flat Response and Shaped Response?
This does the job of converting digitally encoded information into an analog waveform.
What is DAC?
This mic is useful for picking up sound in a very directional manner. These mics are often used on film and TV sets and location shoots.
What is a Shotgun Mic?
This is the speed of sound.
What is approximately 1130 feet per second?
When a fundamental tone is joined by an overtone, at an interval which is fixed.
What are harmonics?
This is the increase in low frequencies that happens as a sound source gets closer to a cardioid mic.
What is the proximity effect?
This is what DSP stands for.
What is Digital Signal Processing
