Audio 7 Flashcards
The opposition to flow of AC or DC electric current , measured in ohms
Resistance
The tendency of an electrical or mechanical system to vibrate, or oscillate at a certain frequency
Resonance
In an audio device or system, a frequency at which ther is a response peak.
Resonant Frequency
Defines how rapidly an audio waveform goes from zero to maximum level.
Rise Time
Refers to a standing wave or the frequency at which one occurs in any given acoustic environment
Room Mode
A condition where further increase in signal level cannot be accommodated. The level where high distortion occurs.
Saturation
Refers to the routing of signal as if goes from the input to output of an audio device or system
Signal Flow
The difference between the nominal or maximum operating level and the noise floor, specified in dB.
Signal-to noise ratio
Refers to a common standard for measurement of intermodulation distortion, and for a standard reference code for identification of frames of film or videotape.
Society of Motion picture and Televsion Engineers (SMPTE)
A feature of many mixing consoles that allows one input signal, one bus
Solo
An acoustic measurement of the sound energy, usually measured in dB SPL.
Sound Pressured Levels (SPL)
In a mixing console, the bus or channel which is used to feed a program to a stereo tape recorder, 2 channel sound system or other stereo equipment
Stereo Bus
A 2 gang fader which simultaneously controls the overall level of the left and right outputs
Stereo master
A sub multiple of the fundamental frequency.
Sub harmonic
In multi track tape recorder, a technique where channels on the record head can be used for tape playback while other channels are being recorded
Sync
