- Validate source files against MIME/signature before conversion.
- Run conversion on representative fixture sizes from the sample library.
- Verify output format integrity, metadata, and playback/rendering behavior.
- Benchmark throughput and resource cost before production rollout.

Haeufige Fehlermuster
- Converting malformed MP3 files without pre-validation causes inconsistent outputs.
- Assuming all AMR readers parse metadata identically creates production regressions.
- Skipping fixture size diversity leads to blind spots in memory and throughput behavior.
- Deploying conversion changes without rollback thresholds increases incident risk.
QA-Checkliste vor dem Rollout
1. Validate MIME/signature for incoming MP3 fixtures.
2. Run conversion against small, medium, and large MP3 samples.
3. Verify structural integrity of generated AMR output.
4. Confirm metadata parity (timestamps, labels, embedded fields).
5. Benchmark conversion latency and resource usage under load.
6. Document fallback path and rollback trigger thresholds.
