1 TB free audio storage

Hear how close your cover is to the original.

Upload two tracks: a cover and the original, or two takes of your own. Ask how close they are. Scarleta aligns them bar-by-bar and measures how alike they sound, right in the chat.

How it works

No setup, no plugins. Just ask, and get the file back.

Step 1

Upload both recordings

Drop two audio files into the Scarleta chat: the reference track and the one you want to compare against it.

Step 2

Ask how they compare

Type it in plain words: "how close is my cover to the original?" The AI figures out which analysis to run. No settings, no code.

Step 3

See where they line up

Get a bar-by-bar alignment showing where the two recordings match and drift, plus a sounds-alike similarity score, laid out right in the conversation.

Built-in storage

Every result is saved to your library, 1 TB free.

The files you bring and the comparison report results you get are kept in one place, so you can come back, compare earlier versions, share a link, or ask across everything you’ve stored, whenever you want.

Recipes

Make a comparison report one step in a pipeline you run by name.

Chain it with other steps into a recipe you design once, then run on a single file in chat or on thousands at once.

For developers

Do this at scale with the API

Running take-vs-reference comparisons over many pairs? Send them to a compare recipe through the batch API and let a webhook call you back when each one is done.

Frequently asked questions

What do I get back?

A bar-by-bar alignment map showing where the two recordings line up and where they drift, plus a similarity score for how alike they sound. You can see it as a chart right in the chat, and export the analysis as CSV or JSON to use in your own tools.

What can I compare?

Any two recordings: a cover against the original, a remaster against the master, or two takes of your own performance. Upload both and ask.

How much does it cost?

You pay per second of audio: $0.10 per minute, from prepaid tokens (1 token = 1 second). New accounts start with 300 free tokens, and top-ups start at $10. No subscription.

Do I need to install anything?

No. Upload both tracks in the Scarleta chat and ask. It runs in your browser with nothing to download.

Can I compare a lot of recordings from my own app?

Yes. Developers can send many comparisons at once through our API and get called back by webhook when every one is done. See the docs.
