What happened
Michael Martin's Bumbershoot Software site details how the ZX Spectrum's single-bit piezoelectric speaker was coaxed into playing multichannel music through pulse-width modulation and clever audio encoding. The article traces the lineage from early beeps to Tim Follin's hand-coded 1980s chiptunes for games like Agent X and Raw Recruit, and links to demos like 'We are Vocoders.'
Why it matters
This is cultural and educational, not actionable. The pulse-width modulation and 1-bit audio encoding techniques are conceptually interesting for anyone learning how sound hardware works at the lowest level, but there is nothing here that changes what a working builder should ship or decide today.
Discussion angle
How extreme hardware constraints forced creative engineering — and whether modern AI-assisted coding makes us lazier or just shifts constraints elsewhere.
