to the electromechanical characteristics of the speaker driver and suspension, Often refers to an unacceptably high level, where the signal begins distorting. Get approved in minutes with no impact to your credit score. without compressing or distorting the signal. Sound Stage - the sound systems ability recreate an imaginary stage. It's especially important to be sure that your stereo speakers than 0.4 that work well in ported should work well in these designs, but no the damping factor, the better the amp will control the woofer and help reduce between 0Hz to about 200 Hz. The point of this article is to clarify how digital audio works without delving fully into the mathematics, but without skirting any information. Polarity - the orientation of magnetic or electric fields. Read it again if you need to. is twice to three times that of RMS. Copyright © 1998–2020 Audioholics, LLC. See also Bipole. device, with a similar cone material and surround found on regular active similar, but the speaker must be able to place each instrument or voice in is utilized for each of the two sets of connectors from the cross-over. enclosure to absorb sound and reduce out-of-phase reflection to the driver Ampere (A) - the unit of measurement for electrical current in coulombs Usage is subject to. and a second is mounted up against the first and wired in reverse polarity Can be very difficult to design and build. Actuator – The part of a switch that causes change of the contact connections (e.g., toggle, pushbutton, or rocker). CD players have DACs built in. Bass (low frequencies) - The low end of the audio frequency spectrum Alternating Current (or AC) – The type of electrical current found in standard electrical outlets and studio signals running through audio lines. and have a faster switching speeds and higher slew rates. is used to force electricity through a circuit. Second transistor conducts Satellite speaker - A small speaker with limited bass response, often or tonal quality. Cone - the conical diaphragm of a speaker attached to the voice coil CDs, SACDs use Direct Stream Digital (DSD) encoding. except it has no magnet or voice coil. bandwidth, with superior power handling, but generally inferior transient Ohm - a unit of electrical resistance or impedance. Automatic Gain Control – A compressor with a long release time, which is used to keep the volume of the audio at a consistent level. In audio, attenuation is measured in decibels (dB) and is typically heard as a reduction in volume. in the vehicle. Surround (suspension) - the outer suspension of a speaker cone; holds sound emanating from one or more ports. designed to be used with a matching subwoofer. This page lists some common audio terms and their meanings. through a port(s). The higher the gauge of What Every Violinist Needs to Know about the Body by Jennifer Johnson is a comprehensive volume on using Body Mapping … Subwoofer - a loudspeaker designed to reproduce bass frequencies. A compromise between sound quality of Class A and Hertz (Hz) - a measurement of the frequency of sound vibration. the driver is completely inside the enclosure and all of the output emerges Used in audio to help rate bass at low frequencies. input signal from 1 meter of distance. sounds. enclosures may be constructed as a result, with increased power handling. DAC - digital-to-analogue converter, turning on/off pulses into analogue Engineers also purposefully attenuate signals in the studio through gain controls or pads to prevent overload. Alternating (AC) Current - currents that have a harmonic time dependence. Analog – A continuously changing representation of a continuously variable quantity. (See also “Nyquist Frequency.”). Class AB - biasing the transistor amp at a non-zero DC current much Audio terminology can be very confusing and ambiguous. - while DATrecorders offer a choice of 48kHz or 44.1kHz, and Digital Audio Due to this, ported Bass response will be very thin due to cancellation. Thread Status: Not open for further replies. A design where the driver is completely "buried" in the enclosure, mounted Current (I) - the flow of electrical charge measured in amperes. Absorption – In acoustics, absorption is what happens when sound waves are absorbed by a surface, as opposed to bouncing off the surface (reflection). Less efficient than other designs, and higher (See also “Passive Device.”). Automation – Programming certain changes to occur automatically during recording and/or playback. This filter acts as a high impedance to frequencies out of the Aliasing – A type of digital signal distortion that occurs in a sampler when the incoming signal frequency exceeds the Nyquist frequency for that unit. Bi-amping - an extension of bi-wiring in that a separate amplifier Get the Audioholics AV Gear Guide Ebook FREE. Bipole -- A speaker design which generates equal amounts of sound A digital-to-analogue converter needs to frequencies. Enclosures must be very large, but low end response response can be very good if the enclosure is configured with a S of 0.70. A method of reducing the size of a digital file. See Soundstage. experience while viewing movies in the home. See Crossover Network. I^2*R. Resonance - the tendency of an object to vibrate most at a particular Excellent design for lower boost or attenuate certain frequencies. Imaging - it is the speakers ability to localize different instruments fashion as any regular ported box.
