How should I use the AMR manifest endpoint?

Fetch manifest JSON to pin fixture names, sizes, hashes, and MIME expectations in automated tests.

Why does this format have a category-specific hub?

A category-specific hub keeps assumptions aligned with practical workflows and related format alternatives.

AMR Format Hub

AMR (.amr) is a speech-focused audio codec used in telephony scenarios. Use sample AMR files to test decoder support, transcoding compatibility, and voice-processing pipelines.

Implementation Notes

Use the manifest endpoint for deterministic fixture selection in CI, then validate MIME/type detection against actual parser output.

If this format appears in multiple categories, prefer category-specific hub pages to keep test assumptions aligned with real usage.
