Introducing Quota Stems: A Free, Non-Destructive Stem Separator for macOS & Windows

We are thrilled to announce the official launch of Quota Stems, the newest addition to the Rare Data Network software family.

Quota Stems is a completely free standalone application designed to make stem separation accessible, high-quality, and incredibly versatile for producers, DJs, and content creators. Whether you are looking to remix a track, create a backing instrumental, or isolate vocals for a project, Quota Stems handles it all directly on your local machine—no subscriptions, no cloud credits, and no paywalls.

Why Quota Stems?

While there are many stem separators on the market, many suffer from "destructive" separation, where recombining the stems results in audio artifacts or phasing issues.

Quota Stems was built to solve this. We utilize a non-destructive separation algorithm, meaning the extracted stems (Vocals, Drums, Bass, and Other) can be stacked back together in your DAW to perfectly recreate the original file with zero loss in quality. This makes it an essential utility for remixing and critical listening.

Key Features

100% Free & Local

Runs entirely on your computer (macOS or Windows). No internet connection is required for processing, ensuring your data stays private.

Universal Import

Drag and drop audio or video files directly into the app. You can also import directly from a URL or even a Playlist (e.g., YouTube), and the app will batch download and process every track automatically.

Video-Native Workflows

Unlike most audio tools, Quota Stems supports video containers natively. You can import a video file and export your stems as video files. This is perfect for content creators who need to strip vocals from a video clip while keeping the video track intact.

Instant Instrumentals

Need an instrumental version of a song quickly? The "Export Instrumental" feature automatically mixes the non-vocal stems and exports a ready-to-use file.

Quota Mini Integration

For users of our dictation helper, Quota Mini, Quota Stems creates "handoff" files, allowing you to easily send isolated vocal tracks to Quota Mini for transcription.
