The 80 to 240 Millisecond Bursts Needed Packet and Audio Timelines Together

Short audible failures can be network gaps, scheduling gaps or local conversion artifacts.

The lab result behind The 80 to 240 Millisecond Bursts Needed Packet and Audio Timelines Together changed the implementation more than the first hypothesis did. Residual LOUP artifacts often appeared as bursts around 80 to 240 milliseconds, which was too structured to diagnose by listening alone.

RTP arrival timestamps, jitter-buffer depth, I2S write timing and audible capture had to be aligned on one timeline. The network showed low overall loss but occasional gaps around 153 to 240 milliseconds and bursts near 80 milliseconds. That evidence shifted attention from generic packet loss toward buffering and scheduling resilience.

Reversibility stayed part of the experiment: preserve the previous artifact, make the change, then prove the new path before promoting it. Evidence marker: 80-240ms-bursts.

Temporal correlation beats intuition. When a glitch has a duration, every subsystem should be asked what it was doing during that same interval. Preserving that distinction is what lets the project increase complexity without losing the ability to explain a regression.
