Uploads and formats
Which files are supported?
MP3, WAV, M4A, FLAC, OGG, and MP4 are supported, up to 50 MB per file.
Why did my upload not start?
Check that the file format and size are supported and keep the page online. If the upload was interrupted, choose the file again and resubmit it.
Can I close the page after uploading?
Yes. After the upload is submitted successfully, processing continues in the background. You can check its status later in Transcriptions.
Transcription and results
How long does transcription take?
It depends on audio length, the task queue, and model processing. The details page continuously shows the current stage.
What does a result contain?
A successful result includes audio playback, a melody score, a timeline, and downloadable MIDI and result JSON files.
What should I do if transcription fails?
Check the error on the details page, then use Upload again to retry. If the same file repeatedly fails, contact support below.
Is automatic transcription always accurate?
No. Dense accompaniment, reverb, harmony, or quiet vocals can affect the result. Review important results manually.
Account and security
What if I forgot my password?
Choose Forgot password on the sign-in page, submit your account email, and use the secure link in the email to set a new password.
Who can see my audio and results?
Transcriptions are private by default and available only to the current account. Result download links also use short-lived authorization.
How do I change my profile?
After signing in to Studio, open Account settings to update your display name or request a password reset email.
Billing and subscription
What plans are available?
Vocal2Melody offers a Free plan plus Melody and Lead Sheet subscriptions. Current prices, billing periods, and included features are listed on the Pricing page; live checkout may remain unavailable during account verification.
Where do I manage my subscription?
Open Billing & subscription in Studio to view your plan and enter Paddle's secure management portal. You are charged only after reviewing and confirming checkout.
Where can I read the refund policy?
Use the Refund policy link in the site footer. For completed purchases, you can submit cancellation and refund requests through Billing & subscription, the management link in your Paddle receipt, or Paddle Buyer Support.
