In digital audio, it refers to the process of transforming continuous range of values into a finite range of discreet steps, often to correct timing errors.

In digital audio, the process of reducing the volume range of a signal, decreasing the level of loud sounds or amplifying quiet parts, making the entire signal more even.

Virtual Studio Technology, an interface standard for connecting audio synthesizer and effect plugins with audio editors and recording systems.

Digital Audio Workstation, a software platform used for recording, editing, mixing, and producing audio files.

The number of samples of audio carried per second, measured in Hertz. It determines the frequency range of the audio recording.

The number of bits of information in each audio sample, which affects the audio resolution and the dynamic range.

Musical Instrument Digital Interface, a technical standard that describes a communications protocol, digital interface, and connectors that connect a wide variety of electronic musical instruments, computers, and related audio devices.

A time-based audio effect that simulates the reflections of sounds off of surfaces in a space, creating a sense of environment or space.

The process of adjusting the balance between frequency components within an electronic signal. In digital audio, it is commonly achieved by using software filters.

A process or device that removes or attenuates certain frequencies from an audio signal, allowing others to pass.

A form of waveform distortion that occurs when an amplifier is overdriven and attempts to deliver an output voltage or current beyond its maximum capability.

Audio Stream Input/Output, a computer sound card driver protocol for digital audio providing a low-latency and high fidelity interface between a software application and a computer's sound card.

The addition of low-level noise to a digital audio signal in order to mask quantization error when reducing the bit depth of that signal.

An effect that causes different signals to become indistinguishable or aliases of one another when sampled, usually combated with anti-aliasing filters.

The position of a point in time on a waveform cycle, an important concept in the synchronization of audio signals.

An electronic device or software that is used to control the volume of an audio signal. It silences a signal once it falls below a specified threshold.

The magnitude of change in the oscillating variable with each oscillation within an audio wave, determines loudness.

The ratio between the largest and smallest values that a certain quantity can assume. In digital audio, it's often the difference between the loudest and quietest parts of the audio.

A high amplitude, short-duration sound at the beginning of a waveform that occurs in phenomena such as musical sounds, noises or speech.

Fast Fourier Transform, an algorithm to compute the Discrete Fourier Transform (DFT) of a sequence, or its inverse. It converts a signal from its original domain (time or space) to a representation in the frequency domain and vice versa.

Half of the sampling rate of a digital recording, above which aliasing can occur.

An audio processing tool that restricts the maximum level of a signal, ensuring that it does not exceed a specified level, to prevent clipping and distortion.

The delay before a transfer of data begins following an instruction for its transfer, in digital audio it is the time delay between the input and output.

Waveform Audio File Format, a Microsoft and IBM audio file format standard for storing an audio bitstream on PCs.
