A latency-hating emulator of: the Acorn Electron and Archimedes, Amstrad CPC, Apple II/II+/IIe and early Macintosh, Atari 2600 and ST, ColecoVision, Enterprise 64/128, Commodore Vic-20 and Amiga, MSX 1/2, Oric 1/Atmos, early PC compatibles, Sega Master System, Sinclair ZX80/81 and ZX Spectrum.
This is front running some of the stuff that will make the MockingBoard feasible, but isn't strictly tied to that goal.
Primarily:
introduce separate types for mono and stereo samples;
what are currently sample sources become buffer sources, because they deal in whole buffers. The concept of a sample source is introduced, which is something which provides a single sample at a time;
skip_samples and get_samples are combined into apply_samples which takes any one of three semantic options as a template argument — store, mix or ignore — with 'mix' being an addition for in-place accumulation of audio buffers that are within a compound source; and
compound sources can avoid initialising buffers with a zero-fill, sometimes. Whereas previously they couldn't.
