Axial response refers to the measurement of a microphone or loudspeaker’s performance when the sound source or measurement device is positioned along the central axis of the device. Axial Response: Understanding axial response is essential for optimizing the performance of…

Available Power Gain refers to the ratio of the available power output of an amplifier to the input power. It measures how effectively an amplifier increases the power from its input to its output. This gain is equivalent to the…

Available Power Efficiency refers to the ratio of electrical power available at the terminals of an electroacoustic transducer (such as a loudspeaker or microphone) to the acoustical power output of that transducer. This efficiency measure reflects how effectively the electrical…

Auto-reverse is a feature found on some cassette players and other tape-based audio devices that allows for continuous playback of a cassette tape by automatically reversing the tape to play the other side once one side is finished. Here’s a…

Automatic Volume Expansion Definition: Automatic Volume Expansion is a process used to increase the dynamic range of audio signals by automatically adjusting the lower levels while keeping the peak levels constant. This technique helps to counteract the loss of dynamic…

Automatic Volume Control (AVC) Definition: Automatic Volume Control (AVC) is a technology used in audio systems, including radios and high-fidelity reproduction systems, to automatically adjust and regulate the sound volume. This can involve altering the contrast (dynamics) of sound during…

Automatic Volume Compression Definition: Automatic Volume Compression is a process used in audio engineering to reduce the dynamic range of a signal, specifically targeting sounds that exhibit wide variations in volume, such as orchestral music. This reduction is essential for…

Automatic Quiet Gain Control Definition: Automatic Quiet Gain Control is a system that combines automatic gain control (AGC) with muting to manage audio signals. This integrated approach is designed to maintain a consistent audio level while minimizing unwanted noise or…

Automatic Gain Control (AGC) Definition: Automatic Gain Control (AGC) is a system used in amplifiers and receivers to automatically adjust the gain of the signal being processed. This adjustment compensates for variations in input signal strength, ensuring a consistent and…
