What is MixThat?

MixThat gives people a more engaging way to experience stems: interactive in-browser mixing, embeddable playback, and better sharing workflows without building the stack yourself.

It can be useful for:

  • Songwriters, artists, and producers who want listeners to explore the arrangement rather than just press play
  • Labels, publishers, and music companies that want a stronger way to present releases, catalogs, or stems online

Create, Mix, Share, and Embed

With MixThat, you can:

  • Upload your stem or multitrack audio
  • Mix stems directly in the browser
  • Share your track as an interactive, embeddable player
  • Control access with share settings and business-friendly delivery options

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.

For individual songwriters, that means a more distinctive way to present a release, demo, or work in progress. For labels and other music companies, it creates a better way to share stems, campaigns, and interactive listening experiences without building custom tooling.


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 a more interactive way to present music online and invite deeper listener engagement.

For organizations, it also creates a practical way to present stems on-brand and in-context, instead of handing over zip files and hoping the recipient can evaluate them properly.


Why MixThat Exists

Traditional audio players stream a single file at once. MixThat’s streaming engine loads small audio chunks as needed, making multitrack playback practical even with longer tracks and multiple stems.

Behind the scenes, MixThat handles:

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

For individual users, that means less setup and faster sharing. For labels and businesses, it means less product and infrastructure work to get a credible interactive stem experience live.

⚠️ We will discontinue Mix That on 1 September 2026. Unfortunately interest has not been strong enough for it to be feasible for us to continue. We apologise for any disruption this may cause. Stemplayer.js will continue to be freely available on GitHub and we recommend using that to host your own player.
