Hello Waveforms is the ninth album by British electronic musician and record producer, William Orbit. It was released in the UK on 20 February 2006. It is a mostly instrumental ambient record, with only four tracks containing vocals: "Spiral", featuring Kenna and the Sugababes, "They Live In The Sky", sung by Annette and Paulette Morris, and "Bubble Universe", which is based on a song previously recorded with Madonna called "Liquid Love", and has vocals by Laurie Mayer. Mayer also collaborates and co-writes other tracks of the record. All tracks are written by Orbit, either alone or in collaboration with Laurie Mayer and Rico Conning. The second track, "Humming Chorus", is from the opera "Madame Butterfly". In the United States, the album reached number ten on the Billboard Top Electronic Albums chart.
Waveform Audio File Format is a Microsoft and IBM audio file format standard for storing an audio bitstream on PCs. It is an application of the Resource Interchange File Format (RIFF) bitstream format method for storing data in "chunks", and thus is also close to the 8SVX and the AIFF format used on Amiga and Macintosh computers, respectively. It is the main format used on Microsoft Windows systems for raw and typically uncompressed audio. The usual bitstream encoding is the linear pulse-code modulation (LPCM) format.
Waveform Records is an American record label founded in 1994 in Sedona, Arizona with subsequent stops in the San Francisco Bay Area in Mill Valley, Austin, San Diego and currently now on Maui. Waveform specializes in a "sensual and stimulating genre of chill and ambient music" that the label calls "exotic electronica".

Subtractive synthesis is a method of sound synthesis in which partials of an audio signal are attenuated by a filter to alter the timbre of the sound. While subtractive synthesis can be applied to any source audio signal, the sound most commonly associated with the technique is that of analog synthesizers of the 1960s and 1970s, in which the harmonics of simple waveforms such as sawtooth, pulse or square waves are attenuated with a voltage-controlled resonant low-pass filter. Many digital, virtual analog and software synthesizers use subtractive synthesis, sometimes in conjunction with other methods of sound synthesis.
Digital audio is sound that has been recorded in, or converted into, digital form. In digital audio, the sound wave of the audio signal is encoded as numerical samples in continuous sequence. For example, in CD audio, samples are taken 44100 times per second each with 16 bit sample depth. Digital audio is also the name for the entire technology of sound recording and reproduction using audio signals that have been encoded in digital form. Following significant advances in digital audio technology during the 1970s, it gradually replaced analog audio technology in many areas of audio engineering and telecommunications in the 1990s and 2000s.
In statistics and its applications, the root mean square is defined as the square root of the mean square . The RMS is also known as the quadratic mean and is a particular case of the generalized mean with exponent 2. RMS can also be defined for a continuously varying function in terms of an integral of the squares of the instantaneous values during a cycle.
Chiptune, also known as chip music or 8-bit music, is a style of synthesized electronic music made using the programmable sound generator (PSG) sound chips in vintage arcade machines, computers and video game consoles. The term is commonly used to refer to tracker format music which intentionally sounds similar to older PSG-created music, as well as music that combines PSG sounds with modern musical styles.
Wavetable synthesis is a sound synthesis technique used to create periodic waveforms. Often used in the production of musical tones or notes, it was developed by Wolfgang Palm of Palm Products GmbH (PPG) in the late 1970s and published in 1979, and has since been used as the primary synthesis method in synthesizers built by PPG and Waldorf Music and as an auxiliary synthesis method by Ensoniq and Access. It is currently used in software-based synthesizers for PCs and tablets, including apps offered by PPG and Waldorf, among others.
The MOS Technology 6581/8580 SID is the built-in programmable sound generator chip of Commodore's CBM-II, Commodore 64, Commodore 128 and Commodore MAX Machine home computers. It was one of the first sound chips of its kind to be included in a home computer prior to the digital sound revolution.
A power inverter, or inverter, is an electronic device or circuitry that changes direct current (DC) to alternating current (AC).
A waveform monitor is a special type of oscilloscope used in television production applications. It is typically used to measure and display the level, or voltage, of a video signal with respect to time.
The Roland D-50 is a polyphonic 61-key synthesizer produced by Roland and released in 1987. Its features include Linear Arithmetic synthesis, on-board effects, a joystick for data manipulation, and an analogue synthesis-styled layout design. The external Roland PG-1000 (1987-1990) programmer could also be attached to the D-50 for more complex manipulation of its sounds. It was also produced in a rack-mount variant design, the D-550 (1987-1990), with almost 450 user-adjustable parameters.
A vectorscope is a special type of oscilloscope used in both audio and video applications. Whereas an oscilloscope or waveform monitor normally displays a plot of signal vs. time, a vectorscope displays an X-Y plot of two signals, which can reveal details about the relationship between these two signals. Vectorscopes are highly similar in operation to oscilloscopes operated in X-Y mode; however those used in video applications have specialized graticules, and accept standard television or video signals as input.
A rompler is an electronic music instrument that plays pre-fabricated sounds based on audio samples. In contrast to samplers, romplers do not record audio and have limited or no capability for generating original sounds. The term rompler is a portmanteau of the terms ROM and sampler. Both may have additional sound editing features, such as layering several waveforms and modulation with ADSR envelopes, filters and LFOs.
Digital usually refers to something using digits, particularly binary digits.
The microKORG is a MIDI-capable virtual analog synthesizer/vocoder from Korg featuring DSP analog modelling. The synthesizer is built in such a way that it is essentially a Korg MS-2000 with programmable step arpeggiator, a less advanced vocoder, lack of motion sequencing, lack of an XLR microphone input, and in a smaller case with fewer real-time control knobs.
The Software Communications Architecture (SCA) is an open architecture framework that defines a standard way for radios to instantiate, configure, and manage waveform applications running on their platform. The SCA separates waveform software from the underlying hardware platform, facilitating waveform software portability and re-use to avoid costs of redeveloping waveforms. The latest version is SCA 4.1.
A programmable sound generator, or PSG, is a sound chip that generates sound waves by synthesizing multiple basic waveforms, and often some kind of noise generator and combining and mixing these waveforms into a complex waveform, then shaping the amplitude envelope of the resulting waveform using attack, decay, sustain, and release time periods, so that the resulting waveform then mimics a certain kind of sound.
The Korg RADIAS is a virtual analog synthesizer and Vocoder, released by Korg in 2006. The RADIAS' MMT engine was based on the Korg OASYS synthesizer module, providing for several different synthesis methods, two of which may be combined in a single voice e.g. phase distortion synthesis can be combined with subtractive synthesis. The different synthesis methods employed by MMT represent the majority of methods used historically in other Korg synthesizers: digital waveguide synthesis Korg first used in the Korg Z1 and phase distortion synthesis was first used in the Korg DS-8. This flexibility allows for very realistic emulations of past Korg synthesizers, though stays away from trying to emulate the Korg M1 and the Korg Wavestation,. As well as using the in-built waveforms for the basis of sound creation, the RADIAS allows for the input of an external signal which may be routed through the various sound shaping devices. The RADIAS has a comprehensive matrix modulation specification and to further enhance a sound the 'Wave Shaper' module allows for various sound distortion effects.
Corneal pachymetry is the process of measuring the thickness of the cornea. A pachymeter is a medical device used to measure the thickness of the eye's cornea. It is used to perform corneal pachymetry prior to refractive surgery, for Keratoconus screening, LRI surgery and is useful in screening for patients suspected of developing glaucoma among other uses.
Waveform is an action, puzzle game created by Canadian indie developer Eden Industries. The player controls a wave of light as it transmits through space and is able to modify the wave's amplitude and wavelength to line it up with objectives, avoid obstacles, and interact with objects that affect the path of the wave, and the world around it, in various ways.
