Audio signal flow is the path an audio signal takes from source to output. [1] The concept of audio signal flow is closely related to the concept of audio gain staging; each component in the signal flow can be thought of as a gain stage. In typical home stereo systems, the signal flow is usually short and simple, with only a few components.
Signal flow is the path an audio signal will take from source to the speaker or recording device. Signal flow may be short and simple as in a home audio system or long and convoluted in a recording studio and larger sound reinforcement system as the signal may pass through many sections of a large mixing console, external audio equipment, and even different rooms.
Sound reinforcement in a large format system typically involves a signal path that starts with the signal inputs, which may be instrument pickups (on an electric guitar or electric bass) or a microphone that a vocalist is singing into or a microphone placed in front of an instrument or guitar amplifier.
Audio signal processing is a subfield of signal processing that is concerned with the electronic manipulation of audio signals. Audio signals are electronic representations of sound waves — longitudinal waves which travel through air, consisting of compressions and rarefactions.
For example, intermodulation distortion from the third order (IMD3) of a circuit can be seen by looking at a signal that is made up of two sine waves, one at and one at . When you cube the sum of these sine waves you will get sine waves at various frequencies including 2 × f 2 − f 1 {\displaystyle 2\times f_{2}-f_{1}} and 2 × f 1 − f 2 ...
A stereo signal is present that is not mono-compatible. This means that the stereo signal cannot be used as a mono signal and is probably too quiet. -1: There are identical signals on both channels, but the polarity of the signal is reversed on one channel, e.g. as a result of reversed connection cables in one of the two signal paths.
An A/B sound system is a type of sound reinforcement system or public address system. Unlike a more typical sound reinforcement system, an A/B sound system provides two electrically isolated signal paths from microphone to speaker, resulting in a system where signals from two microphones only interact acoustically and never interact electronically.
A diagram of monaural sound. Monaural sound or monophonic sound (often shortened to mono) is sound intended to be heard as if it were emanating from one position. [1] This contrasts with stereophonic sound or stereo, which uses two separate audio channels to reproduce sound from two microphones on the right and left side, which is reproduced with two separate loudspeakers to give a sense of ...
