Audio Engineering and Sound Techniques

These flashcards cover essential vocabulary and concepts related to audio engineering and sound production techniques.

Electrical Current

The flow of electrons in a circuit, measured in Amperes (A).

Electro Motive Force (EMF)

The pressure creating the current, measured in Volts (V).

Resistance

The restriction to the flow of electrons in a conductor, measured in Ohms (Ω).

Power (P)

The amount of energy in the flow of electrons, measured in Watts (W).

dB-SPL

Sound pressure level in air, indicating atmospheric changes in air pressure.

dB-A, B, C

Weighted sound pressure levels filtered to represent human perception of sound.

Monitor Systems

Crucial components of audio systems that assess recording and mix quality.

Speaker Drivers

Components that convert electrical energy into sound energy, including types like Moving coil and Ribbon.

Passive Speaker Systems

Speakers that require an external amplifier to function.

Active (Powered) Speaker Systems

Speakers with a built-in amplifier for easier integration.

Crossover

A set of filters that separates an audio signal into frequency bands.

Frequency Response

The range of frequencies a microphone can accurately capture.

Transient Response

How a microphone responds to fast changes in sound pressure.

Self Noise

Electrical noise generated by the microphone itself.

USB Microphones

Microphones that interface directly with computers, may be dynamic or condenser.

Proximity Effect

A bass boost phenomenon that occurs when a sound source is close to a microphone.

Stereo Mic Techniques

Methods for recording sound using multiple microphones to capture a stereo image.

Coincident Mic Techniques

Microphone arrangements where two mics are placed very close together to capture stereo.

Acoustic Phase Cancellation

Timing differences causing sound from the same source to cancel each other out.

3 to 1 Rule

A guideline for mic placement to avoid acoustic phase cancellation between two microphones.
