In the same timeframe of the late 1980s to mid-1990s, the IBM PC clones using the x86 architecture became more ubiquitous, yet had a very different path in sound design than other PCs and consoles. Early PC gaming was limited to the PC speaker, and some proprietary standards such as the IBM PCjr 3-voice chip. While sampled sound could be achieved on the PC speaker using pulse width modulation, doing so required a significant proportion of the available processor power, rendering its use in games rare.
