Clock Signal's emulated machines produce a 1d video signal, just as real machines do. Its emulated display, therefore, has to:

Composite color is optional for all machines on which it was originally optional. Machines such as the Oric, Electron, and MSX originally shipped with the option of RGB output, so the emulator offers the same.

Sound emulation is generally performed by internal generation of original megahertz-rate audio, which is resampled to the output frequency of the host computer. Therefore just as the video can scale up to modern low-latency high-refresh-rate displays, the audio can scale up to digital output rates such as 96Khz and 192Khz.

That generally allows the emulator to maintain audio latency guarantees completely decoupled from the frame rate. It aims for between 5 and 10ms of audio latency.

Clock Signal also has an SDL-based kiosk mode, which is compatible with Linux and any other target offering SDL 2.x, at least OpenGL 3.2 and C++17, and which attempts to follow ordinary UNIX conventions as to file naming and locations. It is intended to be launched however the user would normally launch something from the command-line; the target use case is to set up a file association in the user's preferred desktop environment and launch emulated applications by double-clicking on them exactly like the user would launch native applications.
