One Bit Sound with the ZX Spectrum

A project explores playing audio through a single bit beeper on the ZX Spectrum, building on previous work with other computers.

The project aims to generate sound using pulse code or pulse width modulation (PWM) on the ZX Spectrum's beeper. While PWM is expected to yield better results, it has not yet been successfully implemented.

Unlike some other computers that use dedicated hardware timers for their buzzers, the ZX Spectrum relies entirely on software for sound output.

The article also touches upon the algorithm for achieving multi-channel music, offering an interesting read for those interested in the topic.

The author notes that while this week's results were not as successful as previous attempts on other platforms, the process of 'reasonable failures' can be instructive.
