  • Audio buffer

    An audio buffer is a block of digital audio samples held in memory between hardware and software, trading processing safety against latency.

  • Bit depth

    Bit depth in digital audio is the number of bits used to store each sample, which sets the noise floor and the dynamic range of a…

  • Digital audio workstation DAW

    A digital audio workstation (DAW) is software for recording, editing, mixing and producing digital audio and MIDI on a computer in one environment.

  • Dither

    Dither in digital audio is low-level noise added before reducing bit depth so quantization error becomes benign noise instead of distortion.

  • Nyquist frequency

    The Nyquist frequency is half the sample rate of a digital audio system and marks the highest frequency it can represent without aliasing.

  • PCM

    PCM, or pulse-code modulation, is the standard method of digital audio that samples a waveform at regular intervals and stores each sample as a number.

  • Sample rate

    Sample rate is the number of times per second a digital audio system measures a signal, which sets the highest frequency it can represent.
