[3] The design of the Polymoog is a hybrid of the electronic organ and the synthesizer using divide-down technology, much like other string synthesizers of the time. Unlike later 1970s polyphonic synthesizers, such as the Yamaha CS-80 and Sequential Circuits Prophet-5 , the Polymoog cannot create each voice from individual oscillators and ...
Equalization, or simply EQ, in sound recording and reproduction is the process of adjusting the volume of different frequency bands within an audio signal. The circuit or equipment used to achieve this is called an equalizer. [1] [2] Most hi-fi equipment uses relatively simple filters to make bass and treble adjustments. Graphic and parametric ...
The 5150 was based on the Soldano SLO-100 which Eddie Van Halen was using at the time and designed to provide high gain saturation as well as a clean channel. [5]While the product was designed around a centered printed circuit board (PCB), its cascading five preamps (actually four preamplifiers and one phase inverter) and four gain stages were implemented in a very simple manner.
Scholz Research & Development, Inc. was the name of the company founded by musician and engineer Tom Scholz to design and manufacture music technology products. Scholz is an MIT-trained engineer who developed many of his skills as a product design engineer working on audio-production equipment at Polaroid in the early 1970s.
When the Columbia LP was released in June 1948, the developers subsequently published technical information about the 33 1 ⁄ 3 rpm, microgroove, long-playing record. [5] Columbia disclosed a recording characteristic showing that it was like the NAB curve in the treble, but had more bass boost or pre-emphasis below about 150 Hz.
Tone control is a type of equalization used to make specific pitches or frequencies in an audio signal softer or louder. It allows a listener to adjust the tone of the sound produced by an audio system to their liking, for example to compensate for inadequate bass response of loudspeakers or earphones, tonal qualities of the room, or hearing impairment.
George Y. Massenburg (born Baltimore, Maryland c. 1947) is a Grammy award-winning recording engineer and inventor.Working principally in Baltimore, Los Angeles, Nashville, and Macon, Georgia, Massenburg is widely known for submitting a paper to the Audio Engineering Society in 1972 regarding the parametric equalizer.
An idealized and extreme smiley face curve shown using a 29-band graphic equalizer. A smiley face curve or mid scoop [1] in audio signal processing is a target frequency response curve characterized by boosted low and high frequencies coupled with reduced midrange frequency power.
