User’ s Guide RMS Level RMS (expanded view) Root Mean Square (RMS) is an audio measurement that correlates signal energy with a reference signal. Neither a peak, nor an average, RMS is derived by squaring all the instantaneous voltages from a waveform, averaging the squared value, and then taking the square root of that value. Thus, RMS is a math[...]

User’ s Guide VU Meter (V olume Unit Meter) VU Meters (expanded view) Probably the  rst audio measurement that many of us learned is the familiar VU meter that we equate with distortion overload. The VU Meter is actually de ned by a speci c set of attributes and response characteristics known as ballistics, which estimate the loudness of[...]

User’ s Guide Note: When using this application on the left and right masters, remember to turn off the enable button in the Pro Audio Lab GUI to disable the T one Generation, as you simply need to see the meters. The Loudness Meter displays both a VU and a Peak Level meter on the same graph. There is no absolute measurement for how the ear hears[...]

User’ s Guide Noise Gener ator The Noise Gener ator This noise generator produces white and pink noise, and has independent burst/ pause ratio, total time, and repetitions. White and pink noise are random signals that include all of the audio frequencies. The noise simulates the random thermal motion of electrons. When either white or pink noise [...]

User’ s Guide Slat e T one Genera tor The Slate T one Gener ator The familiar three-step oscillated tone sequences (like we used to hear at the be- ginning of cassette albums), are known as Slate T ones. They are used to calibrate faders, buses, and meters between consoles and decks to insure that all input and output levels are set to a single r[...]

User’ s Guide The Oscilla tor Oscilla tor Screen The oscillator has many uses in sound testing, as it can zero in on a speci c fre- quency and generate a constant steady tone. For example, the sine wave, having no harmonic content, is very useful in determining distortion in a signal that can cause very apparent changes in tone quality . Level[...]
