Even easier is the 1-bit DPCM codec used on the NES. Go up or down one step each sample depending on the next bit. You can't get a square wave out of it, only a triangle, but it has a nostalgic quality.
- a_cardboard_box 11mo agoThe NES DPCM runs at up to 33kHz, so it actually has double the bitrate of the 2-bit 8kHz encoding used in the article. If you run it at 16kHz to match the bitrate, it will sound much worse.
- kragen 11mo agoThat would be just an integrator connected to a digital pulse signal ("square wave"), wouldn't it? Like https://tinyurl.com/28tcwwqc https://tinyurl.com/28tcwwqc?
