Editing Sound card (section)

===Integrated sound on other platforms===
Many [[home computer]]s have their own motherboard-integrated sound devices: [[Commodore 64]],  [[Amiga]], [[PC-88]], [[FM-7]], [[FM Towns]], [[Sharp X1]], [[X68000]], [[BBC Micro]], [[Acorn Electron|Electron]], [[Acorn Archimedes|Archimedes]], [[Atari 8-bit computers]], [[Atari ST]], [[Atari Falcon]], [[Amstrad CPC]], later revisions of  the [[ZX Spectrum]], [[MSX]],<ref name="hg101_retro">{{cite web|url=http://www.hardcoregaming101.net/JPNcomputers/Japanesecomputers.htm|title=Retro Japanese Computers: Gaming's Final Frontier Retro Japanese Computers|author=John Szczepaniak|publisher=Hardcore Gaming 101|access-date=2011-03-29}} Reprinted from {{citation|title=[[Retro Gamer]]|issue=67|year=2009}}</ref> [[Mac (computer)|Mac]], and [[Apple IIGS]]. [[Workstation]]s from  [[Sun Microsystems|Sun]], [[Silicon Graphics]] and [[NeXT]] do as well.  In some cases, most notably in those of the Macintosh, IIGS, Amiga, C64, SGI Indigo, X68000, MSX, Falcon, Archimedes, FM-7 and FM Towns, they provide very advanced capabilities (as of the time of manufacture), in others they are only minimal capabilities. Some of these platforms have also had sound cards designed for their [[Bus (computing)|bus]] architectures that cannot be used in a standard PC.

Several Japanese computer platforms, including the MSX, X1, X68000, FM Towns and FM-7, have built-in [[FM synthesis]] sound from [[Yamaha Corporation|Yamaha]] by the mid-1980s. By 1989, the FM Towns computer platform featured built-in [[PCM]] [[sample-based]] sound and supported the [[CD-ROM]] format.<ref name="hg101_retro"/>

The custom sound chip on [[Amiga]], named Paula, has four digital sound channels (2 for the left speaker and 2 for the right) with 8-bit resolution{{efn|With patches, 14/15-bit resolution could be accomplished at the cost of high CPU usage.}} for each channel and a 6-bit volume control per channel. Sound playback on Amiga was done by reading directly from the chip RAM without using the main CPU.

Most [[arcade video game]]s have integrated sound chips. In the 1980s it was common to have a separate microprocessor for handling communication with the sound chip.
