Earworm - Support

Questions, feedback, or a transcription that does not look right? Email earworm [at] zebel.ai. We read every message.

If a particular recording transcribes badly, describing it — instrument, length, how it was recorded — is usually enough. Only send an audio file if you are comfortable sharing it with support.

Common questions

Which audio formats can I import?

m4a, mp3, wav, aiff, caf, and flac. You can import from Files, share a recording into Earworm from Voice Memos or any other app via the share sheet, or record directly in the app.

Is there a length limit?

Yes — files up to 10 minutes. Longer recordings should be trimmed before import.

What is included for free?

Five complete transcriptions: full length, full quality, full MIDI export, no watermark and no truncation. The counter is spent only when a transcription is produced, not when you import a file or cancel. After that, a one-time lifetime unlock covers unlimited transcriptions; Apple displays the current local price before purchase. There is no subscription and there are no tokens.

How do I restore a purchase?

Open Settings in Earworm and tap Restore Purchases while signed into the same App Store account used for the purchase. Family Sharing is supported. If the unlock still does not appear, restart the app and contact support with the error text — never send payment-card details.

Why is there no account?

Because there is nothing to sync and no server to sync it with. Everything runs on your device, so an account would only be a place for your data to sit. Your entitlement lives with your Apple ID instead.

Does Earworm upload my audio?

No. The transcription model is bundled in the app and every note is computed on your iPhone. There is no account system, no analytics, and no networking. You can verify this yourself: put the phone in airplane mode and transcribe a recording — everything works. Internet is needed only for App Store purchase operations or when you deliberately open an external link.

The transcription has notes that aren't in my recording. What now?

That is what the sensitivity controls are for, and they are instant — the analysis is cached on your device, so nothing is re-processed when you drag.

• Raise the onset threshold to stop faint or breathy moments being heard as new notes.
• Raise the minimum note length to remove short spurious blips.
• Adjust note splitting if one held note is being chopped into several, or several are being merged into one.
• Turn on monophonic mode for humming, singing, or a single-line instrument — it keeps one note at a time and removes most phantom harmonies.

Then use the piano-roll editor to fix whatever is left, and audition the MIDI over the original recording to check it lands where you expect.

Which instruments work best?

Melodies, vocals, humming, whistling, and single instruments with simple polyphony such as piano or guitar. Earworm is not built for full-band mixes or drums, and it is not a real-time effect.

Can I use Earworm without internet?

Yes — the app is designed for it. See the airplane-mode note above.
