Mirelo sound effects: save API files before access expires

Artists who use Mirelo for video sound effects need audio files they can reopen for a later edit. A link alone cannot provide that archive.

How long can artists access API sound effects?

The October 2 changelog, checked October 8, 2026, states a seven-day retention period for generated API sound effects. Deletion can take up to 14 days. Jobs and results remain available for 24 hours, and download links can expire sooner.

That deletion delay is not a promise of extra download time. The notice concerns developer-API sound effects. It does not establish a seven-day limit for every Studio project or every Mirelo product.

What did Mirelo fix in Resolve?

The same changelog says plugin version 1.6.0 fixes lost paid stems, freezes, incorrect levels, and track placement. These are company-reported fixes. We did not independently test the plugin or establish that those faults persist.

The integration guide, checked October 8, specifies DaVinci Resolve Studio for the plugin. It also describes cost estimates before API generation and a separate check that a job finished successfully.

Impact on users

Our analysis: An artist can finish a video today and still need a different cut next month. A missing sound file can force a replacement or another generation. The useful delivery test is whether the saved project opens with its audio intact.

If an editor or another app uses Mirelo on your behalf, ask which audio files it delivers and retains. Include that answer in the collaborator agreement. A visible waveform alone does not establish a durable backup.

How can you preserve the approved soundtrack?

Save generated effects as separate files alongside the original song master. Reopen the project from those saved files. Listen through transitions, fades, and the final export before release.

Mirelo's September 15 speech-preservation guide, checked October 8, describes a mix, an effects track, and a dialogue track when speech is detected. It warns that separation can change the source audio. That guidance does not establish exact preservation of a mastered song or sung vocals.

Keep the approved song master separate from generated effects. The music video release checklist helps keep the final audio and video versions aligned.
