What is MixThat?

MixThat is a web-based platform for uploading, mixing, and sharing your multitrack and stem audio — all directly in the browser.

It’s designed for creators, musicians, and educators who want to turn complex audio projects into interactive listening experiences without heavy software or technical setup.

Create, Mix, and Share — All in One Place#

With MixThat, you can:

• Upload your stem or multitrack audio
• Mix stems directly in the browser
• Share your track as an interactive, embeddable player

Everything runs in the cloud — no installs, no file transfers, and no complex hosting setup. Your listeners can engage with your tracks immediately through our powerful Stem Player.

Powered by the Stem Player#

The Stem Player is MixThat’s heart — a fully customizable web component that can be embedded on any website. It lets listeners:

• Mute, solo, or adjust individual stems
• Loop and zoom in on regions
• Experience your track interactively, not passively

It’s an entirely new way to present your music online.

Why Choose MixThat?#

Traditional audio players stream a single file at once. MixThat’s advanced streaming engine only loads small audio chunks as needed — making it lightweight and ultra-fast, even with many stems or long tracks.

Behind the scenes, MixThat handles:

• High-speed CDN delivery
• Automatic transcoding for multiple formats
• Secure and efficient cloud hosting

You focus on your music. MixThat handles the rest.
