  2. Audio headset - Wikipedia

    en.wikipedia.org/wiki/Audio_headset

    General 3.5 mm computer headsets come with two 3.5 mm connectors: one connecting to the microphone jack and one connecting to the headphone/speaker jack of the computer. 3.5 mm computer headsets connect to the computer via a sound card, which converts the digital signal of the computer to an analog signal for the headset. USB computer headsets ...

  3. Audio and video interfaces and connectors - Wikipedia

    en.wikipedia.org/wiki/Audio_and_video_interfaces...

    Video In Video Out, usually seen as the acronym VIVO (commonly pronounced vee-voh), is a graphics card port which enables some video cards to have bidirectional (input and output) video transfer through a Mini-DIN, usually of the 9-pin variety, and a specialised splitter cable (which can sometimes also transfer sound).

  4. Audio induction loop - Wikipedia

    en.wikipedia.org/wiki/Audio_induction_loop

    The first patented magnetic induction loop communication system was invented by Joseph Poliakoff (grandfather of Sir Martyn Poliakoff) in Great Britain in 1937. [6] [7] [8] The pickup coil in a hearing aid is known as a telecoil (or T-coil) because its early form was to pick up a magnetic field from coils within a telephone. These were included ...

  5. Audio Stream Input/Output - Wikipedia

    en.wikipedia.org/wiki/Audio_Stream_Input/Output

    Audio Stream Input/Output (ASIO) is a computer audio interface driver protocol for digital audio specified by Steinberg, providing high data throughput, synchronization, and low latency between a software application and a computer's audio interface or sound card.

  6. Headphones - Wikipedia

    en.wikipedia.org/wiki/Headphones

    Headsets are made with either a single-earpiece (mono) or a double-earpiece (mono to both ears or stereo). The microphone arm of headsets is either an external microphone type where the microphone is held in front of the user's mouth, or a voicetube type where the microphone is housed in the earpiece and speech reaches it by means of a hollow tube.

  7. Line level - Wikipedia

    en.wikipedia.org/wiki/Line_level

    Most of the voltage asserted by the output appears across the input impedance and almost none of the voltage is dropped across the output. [5] The line input acts similarly to a high impedance voltmeter or oscilloscope input, measuring the voltage asserted by the output while drawing minimal current (and hence minimal power) from the source.

  8. Audio feedback - Wikipedia

    en.wikipedia.org/wiki/Audio_feedback

    Block diagram of the signal-flow for a common feedback loop. [1]: 118 Audio feedback (also known as acoustic feedback, simply as feedback) is a positive feedback situation that may occur when an acoustic path exists between an audio output (for example, a loudspeaker) and its audio input (for example, a microphone or guitar pickup).
