NES Audio: Brief Explanation of Sound Channels

/ retrogameaudio
Before jumping into more details, I wanted to take a step back and share a quick review of the Nintendo's sound channels. Some details are left out, like the frequencies available, why the system is mono, samples that aren't DPCM, etc. But anything I left out has potential to be explored further in a separate blog post. :)
