The iconic ABBA 1976 song was inspired by the musical Cabaret and is all juicy, darker bass-registers, an unrelenting disco beat and uncharacteristically hammered, insistent keys through the treble.
Sound reinforcement in a large format system typically involves a signal path that starts with the signal inputs, which may be instrument pickups (on an electric guitar or electric bass) or a microphone that a vocalist is singing into or a microphone placed in front of an instrument or guitar amplifier.
The microphone's output is usually low-pass filtered. [25] [28] A simple surround microphone configuration involves the use of a front array in combination with two backward-facing omnidirectional room microphones placed about 10–15 meters away from the front array. If echoes are notable, the front array can be delayed appropriately.

This means the microphone must be positioned precisely equidistant from the two speakers if 'comb-filter' effects (alternate peaks and dips in the measured room response at that point) are to be avoided. Positioning is best done by moving the mic from side to side for maximum response on a 1 kHz tone, then a 3 kHz tone, then a 10 kHz tone.
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.
In addition, just before the Frogs sample begins, the song incorporates a musical sample from the intro of noted go-go band E.U.'s song "Knock Him Out Sugar Ray". Beck earned the Grammy Award for Best Male Rock Vocal Performance for the song. In October 2011, NME placed it at number 76 on its list of 150 Best Tracks of the Past 15 Years. [3]
For CD audio, this is 44,100 samples per second, 16 bits per sample, and 2 channels for stereo audio leading to 1,411,200 bits per second. However, this space can be greatly reduced using audio compression. In audio compression, audio samples are processed using an audio codec.
