Pcm onebit pulse density: threshold inclusive · case 02

An exact pulse threshold is delayed by one sample.

Member previewVariant 2 · 3 implementations · 8 checks per implementation

Case contract

Convert bounded nonnegative PCM levels no greater than denominator into a deterministic one-bit pulse-density stream, preserving fractional accumulator state.

Why this case matters

Offline PCM interchange uses these exact bounded packet and sample representation decisions.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
oracle 1	`[[0, 0, 1, 0], 5]`	`[[0, 0, 1, 1], 0]`	Failed
