Editing Frequency modulation synthesis (section)

== Applications ==
=== In synthesizers ===
Digital FM synthesis (equivalent to [[phase modulation]] using the time integration of [[instantaneous frequency]]) was the basis of several musical instruments beginning as early as 1974. Yamaha built the first prototype [[digital synthesizer]] in 1974, based on FM synthesis,<ref name=yamaha2014/> before commercially releasing the Yamaha GS-1 in 1980.<ref name="roads"/> The [[Synclavier|Synclavier I]], manufactured by [[New England Digital|New England Digital Corporation]] beginning in 1978, included a digital FM synthesizer, using an FM synthesis algorithm licensed from Yamaha.<ref name=mixmag2006>{{cite journal | title	= 1978 New England Digital Synclavier | url  	= http://www.mixonline.com/news/news-products/1978-new-england-digital-synclavier/383609 | date 	= September 1, 2006 | journal	= Mix | publisher	= Penton Media}}</ref> Yamaha's groundbreaking [[Yamaha DX7]] synthesizer, released in 1983, brought FM to the forefront of synthesis in the mid-1980s.<ref name=":6">{{Cite news |title=The top 10 classic synth presets (and where you can hear them) |language=EN-GB |work=[[MusicRadar]] |url=https://www.musicradar.com/news/tech/the-top-10-classic-synth-presets-and-where-you-can-hear-them-637677 |access-date=October 19, 2018}}</ref>

=== In PCs, arcades, game consoles, and mobile phones ===
FM synthesis also became the usual setting for games and software up until the mid-nineties. Sound cards for [[IBM PC compatible]] systems like the [[AdLib]] and [[Sound Blaster]] popularized [[Yamaha Corporation|Yamaha]] chips like the [[Yamaha YM3812|OPL2]] and [[Yamaha YMF262|OPL3]]. Other computers such as the Sharp [[X68000]] and [[MSX]] ([[Yamaha CX5M|Yamaha CX5M computer unit]]) utilize the [[Yamaha YM2151|OPM]] sound chip (with later CX5M units using the [[Yamaha YM2164|OPP]] sound chip). The [[NEC]] [[PC-88]] and [[PC-98]] computers use either the [[Yamaha YM2203|OPN]] and [[OPNA]] sound chips.

For arcade systems and game consoles, OPM was used in many arcade boards from the 1980s and 1990s (including [[Sega]]'s [[Sega System 16|System 16]] and [[Capcom]]'s [[CP System]] arcade boards); OPN was also used in some arcade boards in the 1980s. [[OPNB]] was notably used in [[SNK]]'s [[Neo Geo]] arcade (MVS) and home console (AES) machines, as well as being used as the main basic sound generator in [[Taito]]'s arcade boards (with a variant of the OPNB being used in the [[Taito Z System]] board). The related [[OPN2]] was used in Sega's [[Sega Genesis|Mega Drive (Genesis)]], [[Fujitsu]]'s [[FM Towns Marty]], and some of Sega's [[List of Sega arcade system boards|arcade boards]] (e.g. Sega System C-2 and Sega System 32) as one of its sound generator chips.

FM synthesis was also used on a wide range of mobile phones in the 2000s to play ringtones and other sounds, using the [[SMAF|Yamaha SMAF]] format.
