# Audio streaming chunk latency audit

## Description
Audits continuous audio streaming inference chunk sizes and Real-Time Factor (RTF) latency bounds.

## Category
`serving`

## Tags
`serving`, `audio`, `streaming`, `rtf`, `real-time`

## When to Use
Audit real-time speech-to-text and voice companion pipelines to ensure generation stays ahead of playback.

## Operational Limitations
Calculates RTF ratios based on chunk durations; does not process PCM audio streams.

## Verification Script
Run the deterministic verification checker:
```bash
python3 scripts/check.py examples/synthetic.json
```
Exit codes:
- `0`: Check passed and thresholds satisfied.
- `1`: Threshold breach or operational violation detected.
- `2`: Schema error or invalid usage.

## What the checker recomputes

These declared fields must match the other inputs. The tolerance is 0.02, or 0.1% of the recomputed value when that is larger.

- `rtf` = div(processing_duration_sec, audio_chunk_duration_sec)

The original threshold checks still apply:

- `rtf` must not be > `max_allowed_rtf`.

Every other declared field is type-checked. A negative value is rejected except for deltas, drifts, and gains. A type check does not, by itself, prove the measurement.

`population` and `observedAt` are required. The bundled examples are synthetic fixtures, not market measurements.

```bash
python3 scripts/check.py examples/synthetic.json
python3 scripts/check.py examples/contradiction.json
python3 scripts/check.py examples/broken.json
```

Exit 0 is a pass, exit 1 is a review, and exit 2 is invalid input. A pass does not certify a provider, a regulation, a release, or a price.
