The Cheetah Marketing Sound Sampler (1986) was an Analogue to Digital converter system that attached to the system bus connection of the ZX Spectrum home computer.
The sampler included a microphone with an audio preamplifier, an 8 bit analogue to digital converter and an audio output amplifier for impedance matching purposes. The software for the unit was written entirely in Z80 machine code and featured a menu driven interface and an ability to play back a recorded sound shifted over a two octave frequency range using the computer's rudimentary keyboard as a piano keyboard. [1] Although Cheetah Marketing publicised the unit as suitable for home or professional use, reviews identified that the cheapness of the equipment, the lack of polyphony, and the capabilities of the software limited the usefulness of the product to the amateur market. [2] [1]
Accompanying the main software package, the designers Speedwell Software created a real-time sound processing unit that contained a frequency shifter, sound chopper or Dalek voicebox effect, Echo, reverb and a very strange sound effect called a Bubbelizer that was a failed attempt at a phase shifter.[ citation needed ]
The Cheetah Sound Sampler, although crude and cheap, was one of many such electronic devices that introduced home computer owners to the possibilities of digital recording and the principles of electronic music that was, at the time, still reserved for a relative few who had the resources to buy expensive professional and semi-professional equipment.[ citation needed ]
The Sound Sampler sold relatively few units due to stiff competition from contemporary manufacturers and the poor build quality of the product.[ citation needed ]
A digital synthesizer is a synthesizer that uses digital signal processing (DSP) techniques to make musical sounds. This in contrast to older analog synthesizers, which produce music using analog electronics, and samplers, which play back digital recordings of acoustic, electric, or electronic instruments. Some digital synthesizers emulate analog synthesizers; others include sampling capability in addition to digital synthesis.
An electronic musical instrument or electrophone is a musical instrument that produces sound using electronic circuitry. Such an instrument sounds by outputting an electrical, electronic or digital audio signal that ultimately is plugged into a power amplifier which drives a loudspeaker, creating the sound heard by the performer and listener.
An effects unit, effects processor, or effects pedal is an electronic device that alters the sound of a musical instrument or other audio source through audio signal processing.
A set-top box (STB), also known as a cable box or receiver and historically television decoder or a converter, is an information appliance device that generally contains a TV-tuner input and displays output to a television set and an external source of signal, turning the source signal into content in a form that can then be displayed on the television screen or other display device. They are used in cable television, satellite television, and over-the-air television systems as well as other uses.
Digital music technology encompasses the use of digital instruments, computers, electronic effects units, software, or digital audio equipment by a performer, composer, sound engineer, DJ, or record producer to produce, perform or record music. The term refers to electronic devices, instruments, computer hardware, and software used in performance, playback, recording, composition, mixing, analysis, and editing of music.
A music sequencer is a device or application software that can record, edit, or play back music, by handling note and performance information in several forms, typically CV/Gate, MIDI, or Open Sound Control, and possibly audio and automation data for digital audio workstations (DAWs) and plug-ins.
Multitrack recording (MTR), also known as multitracking, is a method of sound recording developed in 1955 that allows for the separate recording of multiple sound sources or of sound sources recorded at different times to create a cohesive whole. Multitracking became possible in the mid-1950s when the idea of simultaneously recording different audio channels to separate discrete tracks on the same reel-to-reel tape was developed. A track was simply a different channel recorded to its own discrete area on the tape whereby their relative sequence of recorded events would be preserved, and playback would be simultaneous or synchronized.
Akai is a Hong Kong manufacturer of consumer electronics. It was founded as Akai Electric Company Ltd in Tokyo, Japan, in 1946.
A music workstation is an electronic musical instrument providing the facilities of:
A sampler is an electronic musical instrument that records and plays back samples. Samples may comprise elements such as rhythm, melody, speech, sound effects or longer portions of music.
A rompler is an electronic musical instrument that plays pre-fabricated sounds based on audio samples. The term rompler is a blend of the terms ROM and sampler. In contrast to samplers, romplers do not record audio. Both may have additional sound editing features, such as layering several waveforms and modulation with ADSR envelopes, filters and LFOs.
An electric organ, also known as electronic organ, is an electronic keyboard instrument which was derived from the harmonium, pipe organ and theatre organ. Originally designed to imitate their sound, or orchestral sounds, it has since developed into several types of instruments:
The Roland MT-32 Multi-Timbre Sound Module is a MIDI synthesizer module first released in 1987 by Roland Corporation. It was originally marketed to amateur musicians as a budget external synthesizer with an original list price of $695. However, it became more famous along with its compatible modules as an early de facto standard in computer music. Since it was made prior to the release of the General MIDI standard, it uses its own proprietary format for MIDI file playback.
A MIDI controller is any hardware or software that generates and transmits Musical Instrument Digital Interface (MIDI) data to MIDI-enabled devices, typically to trigger sounds and control parameters of an electronic music performance. They most often use a musical keyboard to send data about the pitch of notes to play, although a MIDI controller may trigger lighting and other effects. A wind controller has a sensor that converts breath pressure to volume information and lip pressure to control pitch. Controllers for percussion and stringed instruments exist, as well as specialized and experimental devices. Some MIDI controllers are used in association with specific digital audio workstation software. The original MIDI specification has been extended to include a greater range of control features.
Doepfer Musikelektronik GmbH is a German manufacturer of audio hardware, mostly synthesizer modules, based in Gräfelfing, Upper Bavaria and founded by Dieter Döpfer. The product range covers analog modular systems, MIDI controllers, MIDI hardware sequencers, MIDI-to-CV/Gate/Sync Interfaces, MIDI master keyboards and special MIDI equipment.
Aphex is a brand of audio signal processing equipment. Aphex Systems was founded in 1975 in Massachusetts. The name is shorthand for "Audio Perception Heterodyne Exciter", in reference to its original product, the Aphex Aural Exciter. The company changed its name to Aphex in 2010.
Cheetah Marketing was a United Kingdom-based company that produced electronic music-related hardware products and software for home computer systems during the 1980s. They later changed their name to Cheetah International Ltd.
An exciter is an audio signal processing technique used to enhance a signal by dynamic equalization, phase manipulation, harmonic synthesis of (usually) high frequency signals, and through the addition of subtle harmonic distortion. Dynamic equalization involves variation of the equalizer characteristics in the time domain as a function of the input. Due to the varying nature, noise is reduced compared to static equalizers. Harmonic synthesis involves the creation of higher order harmonics from the fundamental frequency signals present in the recording. As noise is usually more prevalent at higher frequencies, the harmonics are derived from a purer frequency band resulting in clearer highs. Exciters are also used to synthesize harmonics of low frequency signals to simulate deep bass in smaller speakers.
A synthesizer is an electronic musical instrument that generates audio signals. Synthesizers typically create sounds by generating waveforms through methods including subtractive synthesis, additive synthesis and frequency modulation synthesis. These sounds may be altered by components such as filters, which cut or boost frequencies; envelopes, which control articulation, or how notes begin and end; and low-frequency oscillators, which modulate parameters such as pitch, volume, or filter characteristics affecting timbre. Synthesizers are typically played with keyboards or controlled by sequencers, software or other instruments and may be synchronized to other equipment via MIDI.
E-mu Systems was a software synthesizer, audio interface, MIDI interface, and MIDI keyboard manufacturer. Founded in 1971 as a synthesizer maker, E-mu was a pioneer in samplers, sample-based drum machines and low-cost digital sampling music workstations.
