Whois & Analysis for fractalaudio.com

A fractal is a mathematical set that exhibits a repeating pattern displayed at every scale.

It is also known as expanding symmetry or evolving symmetry.

If the replication is exactly the same at every scale, it is called a self-similar pattern.

An example of this is the Menger Sponge.

Fractals can also be nearly the same at different levels.

This latter pattern is illustrated in small magnifications of the Mandelbrot set.

Fractals also include the idea of a detailed pattern that repeats itself.

Processor Technology Corporation was a personal computer company founded in April 1975 by Gary Ingram and Bob Marsh in Berkeley, California.

Their first product was a 4K byte RAM board that was compatible with the MITS Altair 8800 computer but more reliable than the MITS board.

This was followed by a series of memory and I/O boards including a video display module.

Popular Electronics magazine wanted a feature article on an intelligent computer terminal and Technical Editor Les Solomon asked Marsh and Lee Felsenstein to design one.

It was featured on the July 1976 cover and became the Sol-20 Personal Computer.

The first units were shipped in December 1976 and the Sol-20 was a very successful product.

The company failed to develop next generation products and ceased operations in May 1979.

An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the power of a signal (a time-varying voltage or current).

An amplifier functions by taking power from a power supply and controlling the output to match the input signal shape but with a larger amplitude.

In this sense, an amplifier modulates the output of the power supply based upon the properties of the input signal.

An amplifier is effectively the opposite of an attenuator: while an amplifier provides gain, an attenuator provides loss.

An electric guitar is a guitar that uses a pickup to convert the vibration of its strings—which are typically made of steel, and which occurs when a guitarist strums, plucks or fingerpicks the strings—into electrical signals.

The vibrations of the strings are sensed by a pickup, of which the most common type is the magnetic pickup, which uses the principle of direct electromagnetic induction.

The signal generated by an electric guitar is too weak to drive a loudspeaker, so it is plugged into a guitar amplifier before being sent to a loudspeaker, which makes a sound loud enough to hear.

The output of an electric guitar is an electric signal, and the signal can easily be altered by electronic circuits to add "color" to the sound or change the sound.

Often the signal is modified using effects such as reverb and distortion and "overdrive", with the growling sound of the latter being a key element of the sound of the electric guitar as it is used in blues and rock music.

An effects unit or pedal is an electronic or digital device that alters how a musical instrument or other audio source sounds.

In the 2010s, most effects use solid state electronics and/or computer chips.

Some vintage effects units from the 1930s to the 1970s and modern reissues of these effects use mechanical components as well (e.g., Leslie rotating speaker, spring reverb, and tape recorder-based echo effects) or vacuum tubes.

Some effects subtly "color" a sound, such as a reverb unit used on a low setting, while others transform it dramatically, such as a distortion pedal used with electric guitar, with the overdrive set to its maximum level.

Musicians, audio engineers and record producers use effects units during live performances or in the studio, typically with electric guitar, electronic keyboard, electric piano or electric bass.

While guitar effects are most frequently used with electric or electronic instruments, effects can also be used with acoustic instruments, drums and vocals.

Rackmounted or audio console-integrated reverb effects are commonly used with vocals in live sound and sound recording.

Examples of common effects units include wah-wah pedals, fuzzboxes and reverb units.
