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.
Signal processing is an electrical engineering subfield that focuses on analyzing, modifying and synthesizing signals, such as sound, images, potential fields, seismic signals, altimetry processing, and scientific measurements. [1]
When altering a signal with a filter, the output signal may differ in time from the signal at the input, which is measured as its phase response. All analog equalizers exhibit this behavior, with the amount of phase shift differing in some pattern, and centered around the band that is being adjusted. Although this effect alters the signal in a ...
The lifecycle of sound from its source, through an ADC, digital processing, a DAC, and finally as sound again. If an audio signal is analog, a digital audio system starts with an ADC that converts an analog signal to a digital signal. [b] The ADC runs at a specified sampling rate and converts at a known bit resolution.
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.
