  2. Measurement microphone calibration - Wikipedia

    en.wikipedia.org/wiki/Measurement_microphone...

    A pistonphone is an acoustical calibrator (sound source) that uses a closed coupling volume to generate a precise sound pressure for the calibration of measurement microphones. The principle relies on a piston mechanically driven to move at a specified cyclic rate, pushing on a fixed volume of air to which the microphone under test is coupled.

  3. Sound Recorder (Windows) - Wikipedia

    en.wikipedia.org/wiki/Sound_Recorder_(Windows)

    Before Windows 7, Sound Recorder could save the recorded audio in waveform audio (.wav) container files.Sound Recorder could also open and play existing .wav files. To successfully open compressed .wav files in Sound Recorder, the audio codec used by the file must be installed in the Audio Compression Manager (ACM); Windows installations dating back to at least Windows 95 came with a selection ...

  4. Audio Stream Input/Output - Wikipedia

    en.wikipedia.org/wiki/Audio_Stream_Input/Output

    ASIO 2.3 introduced monitoring for dropouts in the audio stream. [4] ASIO bypasses the normal audio path from a user application through layers of intermediary operating system software so that an application connects directly to the sound card hardware. Each layer that is bypassed means a reduction in latency (the delay between an application ...

  5. Sound card - Wikipedia

    en.wikipedia.org/wiki/Sound_card

    Input through a microphone connector can be used, for example, by speech recognition or voice over IP applications. Most sound cards have a line in connector for an analog input from a sound source that has higher voltage levels than a microphone. In either case, the sound card uses an analog-to-digital converter (ADC) to digitize this signal.

  6. Smaart - Wikipedia

    en.wikipedia.org/wiki/Smaart

    A computer having a dual-core processor with a clock rate of at least 2 GHz is recommended. [5] Smaart can be set to sample rates of 44.1 kHz, 48 kHz or 96 kHz, and to bit depths of 16 or 24. The software works with computer audio protocols ASIO, Core Audio, WAV or WDM audio drivers. [6]

  7. Audio headset - Wikipedia

    en.wikipedia.org/wiki/Audio_headset

    The microphone arm of headsets may carry an external microphone or be of the voice tube type. External microphone designs have the microphone housed in the front end of the microphone arm. Voicetube designs are also called internal microphone design, and have the microphone housed near the earpiece, with a tube carrying sound to the microphone.

  8. Intel High Definition Audio - Wikipedia

    en.wikipedia.org/wiki/Intel_High_Definition_Audio

    Intel High Definition Audio (IHDA) (also called HD Audio or development codename Azalia) is a specification for the audio sub-system of personal computers. It was released by Intel in 2004 as the successor to their AC'97 PC audio standard.

  9. Mixing console - Wikipedia

    en.wikipedia.org/wiki/Mixing_console

    A sound engineer can use the cue feature to, for instance, get a sound recording they wish to play soon cued up to the start point of a song, without the listeners hearing these actions. The signal from the cue system is fed to the console's headphone amp and may also be available as a line-level output that is intended to drive a monitor ...
