A pinch harmonic (also known as squelch picking, pick harmonic or squealy) is a guitar technique to achieve artificial harmonics in which the player's thumb or index finger on the picking hand slightly catches the string after it is picked, [10] canceling (silencing) the fundamental frequency of the string, and letting one of the overtones ...
Smiley face curves have been popular with some car audio enthusiasts, disc jockeys, electric bass players, home stereo owners and sound reinforcement operators. [ 2 ] [ 3 ] Though the graphic equalizer was intended to tailor a system's response to compensate for venue and performance conditions, the smiley face curve is sometimes applied as a ...
In telecommunication, a standard test tone is a pure tone with a standardized level generally used for level alignment of single links and of links in tandem. [1]For standardized test signal levels and frequencies, see MIL-STD-188-100 for United States Department of Defense (DOD) use, and the Code of Federal Regulations Title 47, part 68 for other Government agencies.
String gauge refers to the thickness and diameter of a guitar string, which influences the overall sound and pitch of the guitar depending on the guitar string used. [17] Some alternative tunings are difficult or even impossible to achieve with conventional guitars due to the sets of guitar strings, which have gauges optimized for standard tuning.
An audio analyzer is a test and measurement instrument used to objectively quantify the audio performance of electronic and electro-acoustical devices. Audio quality metrics cover a wide variety of parameters, including level, gain, noise, harmonic and intermodulation distortion, frequency response, relative phase of signals, interchannel crosstalk, and more.
This device allows matching the frequency of the xenon flash lamp to the frequency of vibration of the string. In a dark room, this clearly shows the waveform. Otherwise, one can use bending or, perhaps more easily, by adjusting the machine heads, to obtain the same, or a multiple, of the AC frequency to achieve the same effect. For example, in ...
A440 (also known as Stuttgart pitch [1]) is the musical pitch corresponding to an audio frequency of 440 Hz, which serves as a tuning standard for the musical note of A above middle C, or A 4 in scientific pitch notation. It is standardized by the International Organization for Standardization as ISO 16.
Trey Gunn (Crimson's warr guitar player from 1994 to 2003) and Markus Reuter [37] have adapted new standard tuning for their 8- and 10-string instruments; in 2007 Reuter used a B ♭-F-C-G-D-A-C-D tuning. [37] Finnish musician Heikki Malmberg uses a 7-string guitar tuned in sew standard tuning with an additional low F. [38]
