A digital synthesizer is a synthesizer that uses digital signal processing (DSP) techniques to make musical sounds, 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 ...
Early digital systems may have suffered from a number of signal degradations related to the use of analog anti-aliasing filters, e.g., time dispersion, nonlinear distortion, ripple, temperature dependence of filters etc. [20]: 8 Using an oversampling design and delta-sigma modulation, a less aggressive analog anti-aliasing filter can be ...
An analog synthesizer (British English: analogue synthesiser) is a synthesizer that uses analog circuits and analog signals to generate sound electronically. The earliest analog synthesizers in the 1920s and 1930s, such as the Trautonium , were built with a variety of vacuum-tube (thermionic valve) and electro-mechanical technologies.
Digital synthesizers, such as the Yamaha DX7, became widely popular. [ 4 ] The 1990s and 2000s witnessed the explosive growth of electronic dance music and its various subgenres, driven by the accessibility of digital music production tools and the rise of computer-based software synthesizers.
[9]: 63 In 1988, the Japanese manufacturer Korg released the M1, a digital synthesizer workstation featuring sampled transients and loops. [27] With more than 250,000 units sold, it remains the bestselling synthesizer in history. [27] The advent of digital synthesizers led to a downturn in interest in analog synthesizers in the following decade.
Direct digital synthesis (DDS) is a method employed by frequency synthesizers used for creating arbitrary waveforms from a single, fixed-frequency reference clock. DDS is used in applications such as signal generation , local oscillators in communication systems, function generators , mixers, modulators , [ 1 ] sound synthesizers and as part of ...
In 1983, Yamaha released the DX7 digital synthesizer, which was cheaper than its analog counterparts. Studios and producers increasingly used digital synthesizers over analog synthesizers into the late 1980s and 1990s, [1] causing many analog synthesizer companies, including Moog, ARP and Sequential Circuits, to go out of business.

An analog modeling synthesizer is a synthesizer that generates the sounds of traditional analog synthesizers using digital signal processing components and software algorithms. Analog modeling synthesizers simulate the behavior of the original electronic circuitry in order to digitally replicate their tone.
