Does Release Lab upload my audio?

No. Release Lab analyzes audio locally in your browser tab. Your audio file is not uploaded by this tool.

Is Release Lab a certified LUFS meter?

No. Release Lab provides browser-based loudness and peak estimates. Final LUFS and true peak should be verified in a dedicated mastering meter.

What is the Preflight Score?

The Preflight Score is a non-authoritative checklist score based on browser audio QC and release workflow completion. It is not distributor or Spotify approval.

AI disclosure builder

Use this as internal documentation or adapt it where a distributor or platform asks for AI use details.

AI-assisted music generation was used as part of the creative process. Human arrangement, editing, production decisions, mix review, mastering review, release curation, and final upload decisions were completed by the creator. AI use should be disclosed accurately wherever the distributor or platform requests it.
