A software synthesizer or softsynth is a computer program that generates digital audio, usually for music. Computer software that can create sounds or music is not new, but advances in processing speed now allow softsynths to accomplish the same tasks that previously required the dedicated hardware of a conventional

. Softsynths are usually less expensive and can be more portable than dedicated hardware.

Types

Softsynths can cover a range of synthesis methods, including subtractive synthesis (including analog modeling, a subtype), FM synthesis (including the similar phase distortion synthesis), physical modelling synthesis, additive synthesis (including the related resynthesis), and

sample-based synthesis Sample-based synthesis is a form of audio synthesis that can be contrasted to either subtractive synthesis or additive synthesis. The principal difference with sample-based synthesis is that the seed waveforms are sampled sounds or instrument ...

. Many popular hardware synthesizers are no longer manufactured but have been emulated in software. The emulation can even extend to having graphics that model the exact placements of the original hardware controls. Some simulators can even import the original sound patches with accuracy that is nearly indistinguishable from the original synthesizer. Popular synthesizers such as the '' Moog Minimoog'', '' Yamaha DX7'', '' Korg M1'', '' Sequential Prophet-5'', '' Oberheim OB-X'', '' Roland Jupiter 8'', '' ARP 2600'' and dozens of other classics have been recreated in software. Software Synth developers such as Arturia offer virtual editions of analog synths like the Minimoog, the ARP 2600, as well as the Yamaha CS-80
Gforce
produces a Minimoog with sounds designed by Rick Wakeman and version of the ARP Odyssey. Some softsynths are sample-based, and frequently have more capability than hardware units, since computers have fewer restrictions on memory than dedicated hardware synthesizers. Sample libraries may be many gigabytes in size. Some are specifically designed to mimic real-world instruments such as pianos. Sample libraries' formats include ''

'', '' .sf'' or .sf2. Often a composer or virtual conductor will want a "draft mode" for initial score editing and then use the "production mode" to generate high-quality sound as one gets closer to the final version. The draft mode allows for quicker turn-around, perhaps in real time, but will not have the full quality of the production mode. The draft render is roughly analogous to a wire-frame or "big polygon" animation when creating 3D animation or CGI. Both are based on the trade-off between quality and turn-around time for reviewing drafts and changes.
