  2. Monaural sound - Wikipedia

    en.wikipedia.org/wiki/Monaural_sound

    A diagram of monaural sound. Monaural sound or monophonic sound (often shortened to mono) is sound intended to be heard as if it were emanating from one position. [1] This contrasts with stereophonic sound or stereo, which uses two separate audio channels to reproduce sound from two microphones on the right and left side, which is reproduced with two separate loudspeakers to give a sense of ...

    One string (i.e., in piano music, depressing the soft pedal, which alters and reduces the volume of the sound). For most notes in modern pianos, this results in the hammer striking two strings rather than three. Its counterpart, tre corde (three strings), is the opposite: the soft pedal is to be released. unisono (unis)

    en.wikipedia.org/wiki/Loudspeaker_enclosure

    Speaker cabinets are key components of a number of commercial applications, including sound reinforcement systems, movie theatre sound systems and recording studios. Electric musical instruments invented in the 20th century, such as the electric guitar , electric bass and synthesizer , among others, are amplified using instrument amplifiers and ...

  5. Sound reinforcement system - Wikipedia

    en.wikipedia.org/wiki/Sound_reinforcement_system

    A typical sound reinforcement system consists of; input transducers (e.g., microphones), which convert sound energy such as a person singing into an electric signal, signal processors which alter the signal characteristics (e.g., equalizers that adjust the bass and treble, compressors that reduce signal peaks, etc.), amplifiers, which produce a ...

  6. Loudspeaker - Wikipedia

    en.wikipedia.org/wiki/Loudspeaker

    A loudspeaker (commonly referred to as a speaker or, more fully, a speaker system) is a combination of one or more speaker drivers, an enclosure, and electrical connections (possibly including a crossover network). The speaker driver is an electroacoustic transducer [1]: 597 that converts an electrical audio signal into a corresponding sound. [2]

  7. Dynamic range compression - Wikipedia

    en.wikipedia.org/wiki/Dynamic_range_compression

    Most devices capable of compressing audio dynamics can also be used to reduce the volume of one audio source when another audio source reaches a certain level; this is called side-chaining. [13] In electronic dance music , side-chaining is often used on basslines , controlled by the kick drum or a similar percussive trigger, to prevent the two ...

  9. Dipole speaker - Wikipedia

    en.wikipedia.org/wiki/Dipole_speaker

    A dipole speaker works by creating air movement (as sound pressure waves) directly from the front and back surfaces of the driver, rather than by impedance matching one or both outputs to the air. As a result, diaphragm motion below the driver's resonance frequency is constrained primarily by the driver's restoring force (e.g., diaphragm ...
