This is a followup to the previous post on the Sega CD’s PCM sound chip. This post will start by going into more detail on why this chip’s audio output sounds pretty crummy by default, followed by one of two possible solutions that I know of to that problem.

De-smarting the Marshall Uxbridge (sig7.se)
This is the story of a commercially unavailable stereo pair of the bi-amped Marshall Uxbridge, with custom-built replacement electronics: active filters feeding two linear power amps. Listening to this high-fidelity set has brought me immense enjoyment. Play a great album on these near-fields, and the result is close to pure magic! Over and above the accurate reproduction of a wide audio range, the precision and depth of its stereo imaging is stunning.

Phased Array Microphone (2023) (benwang.dev)
A 192-channel phased array microphone, with FPGA data acquisition and beamforming/visualization on the GPU. Phased arrays allow for applications not possible with traditional directional microphones, as the directionality can be changed instantly, after the recording is made, or even be focused at hundreds of thousands of points simultaneously in real time.

SNES and Playstation Cubic Adpcm Interpolation (jsgroth.dev)
It’s been a minute, and I haven’t done a whole lot of emulation work recently, but this is a topic I’ve wanted to do a short post about for a while: a really simple audio enhancement for SNES and PlayStation emulation that works surprisingly well with some games. It’s more noticeable for SNES, but there are some PlayStation games that benefit from this as well!
