Testing contract

Reference control

Scenario: Parse the JSON edit metadata and order all offsets numerically.
Expected result: Three offsets resolve as 0, 250, and 540 ms; crossfade is 14 ms and channel policy remains preserve.

What is a .json file?

JSON (JavaScript Object Notation) is a lightweight, text-based data-interchange format representing objects, arrays, strings, numbers, booleans, and null. It is language-independent, human-readable, and the dominant format for web APIs and configuration. It requires a single well-formed root value.

How to use this file

Use an example JSON file to test parsers and serializers, schema validation, Unicode and number-precision handling, and API request or response processing.

How to use this file for testing

“Audio Edit Metadata JSON 02” is a deterministic Novus Examples fixture for Audio editing, Metadata testing, Config testing. Synthetic foley, ambience, dialogue, loops, stems, cue sheets, and edge cases with documented timing and signal properties for repeatable editing checks.

Documented properties for this file: JSON · 150 bytes. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.

Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.

Creator-audio fixtures are short, synthetic, and deterministic. Check sample rate, channels, duration, cue points, and the published expected result; workflow-kit members connect the media to the brief, prompt plan, and evaluation rubric without an upload.

Import the source at its documented sample rate, apply the stated edit or mix operation, and compare timing, channels, peak behavior, and the expected-output member rather than listening by impression alone.

Code examples

import json

with open("p8-audio-edge-json-02.json") as f:
    data = json.load(f)
print(type(data), len(data))
