THE PRODUCT PROBLEM

Make the audio step part of the product.

Artists often have a vocal and a beat, but not a finished release. Keep that workflow inside your product instead of sending creators elsewhere.

A TESTABLE WORKFLOW

Provide vocal and backing-track URLs, select a style and loudness target, then preview before retrieving the final master.

COMMON QUESTIONS

Answers your team can forward.

Review data handling, rights, and enterprise terms before an integration conversation.

Security and data handling ↗
Can users submit marketplace beats?

Yes, when the user holds the rights or licence needed for the intended processing and release. Your product should make that rights responsibility clear.

Does this replace a complete mixing suite?

This endpoint is a focused vocal-and-backing mix workflow. It is designed for an in-product result, not as a general DAW.
