This is the second of two followups to my post on the Sega CD PCM chip. Where the last post described a way to improve audio quality by applying an audio filter to final mixed PCM chip output, this post will describe an audio enhancement that improves audio quality by changing how the emulated chip itself generates samples.| jsgroth's blog

Since then, I noticed that Sega CD games that use its PCM sound chip have pretty poor audio quality in my emulator - the audio output sounds very noisy and aliased.| jsgroth's blog
