nescript/examples/pong/audio.ne

// pong/audio.ne — sfx + music declarations.
//
// Channel budget (same as war):
//     pulse 1  — every `play Name` sfx
//     pulse 2  — music (TitleTheme + builtin fanfare)
//     triangle — reserved
//     noise    — reserved for a later low-thud on paddle hit
//
// The audio tick is linked in only because the title state uses
// `start_music`, so everything below ends up in PRG ROM.

// ── Sound effects ──────────────────────────────────────────
