Clumi
Summary
You found a karaoke track online, hit download, and got a watermarked MP3 locked behind a signup wall — again. {{input.name}} skips the account creation and ships the instrumental directly.
Upload a file, wait a few minutes, download the separated stems. That is the entire workflow. No software install, no configuration, no account required for the initial free processing quota. The tool handles vocal removal, individual stem isolation (drums, bass, piano, guitar), and noise cleanup in the same interface. The ceiling appears fast: the free tier caps at three files, file duration tops out at 10 minutes, and file size is capped at 100 MB. Teams running batch processing or working with long-form audio hit that wall on the first session and move to a paid tier or a different architecture entirely.
Bottom line: The right call for a karaoke creator who needs a clean instrumental from a three-minute pop track with zero setup — the wrong call for a producer who needs to process an album in one session without per-file limits.

Pros
Sign in to edit- No account required for initial processing, so you get a separated track in minutes without handing over an email address or setting up credentials.
- Runs entirely in the browser across desktop, tablet, and mobile, which means there is no software to install and no local GPU or processing power required — useful when you are on a machine you do not control.
- Covers individual stem isolation beyond just vocals — drums, bass, piano, guitar each get their own extractor — so a producer testing whether a specific instrument can be cleanly removed does not need a second tool.
- Noise removal utilities (echo, reverb, breath, crowd, wind, static) live in the same interface as stem splitting, so cleaning a recorded track before separation does not require switching tools.
- Audio utilities like key/BPM detection, pitch shifting, and audio cutting are bundled, which means a karaoke creator can identify a song's key and trim the track in the same session.
Cons
Sign in to edit- The free quota caps at three files with no reset mechanism described in the page content — a producer evaluating the tool for an album split exhausts the trial before finishing a single project and must upgrade or leave.
- File duration is hard-capped at 10 minutes and file size at 100 MB, so DJ sets, live recordings, or extended mixes cannot be processed as single files; workarounds require manually cutting audio before upload, adding steps that defeat the speed advantage.
- There is no API and no batch processing capability at any tier, which means any team that needs to automate stem separation — even a small one running nightly remix pipelines — has to replace this tool with a service that exposes a programmatic interface, such as a self-hosted Demucs instance or a vendor API.
- No self-hosted option exists, so teams operating under data residency or content confidentiality requirements cannot use the service at all — unreleased tracks processed here transit Clumi's servers.

Curated lists that include this category
{{input.name}} is a browser-based audio separation tool from Clumi that splits a song into isolated components — vocals, instrumentals, and individual stems like drums, bass, piano, and guitar — without requiring any software installation or account creation. The workflow is upload-and-wait: you drop an audio file into the browser interface, the AI processes it server-side, and you download the separated tracks. The tool also includes noise removal utilities covering echo, reverb, breath sounds, crowd noise, and wind noise, plus audio utilities like a key and BPM finder, pitch changer, and audio cutter.
The differentiating feature relative to desktop-based alternatives is pure accessibility. Because processing runs in the browser across desktop, tablet, and mobile, there is no platform dependency and no local compute requirement. For a karaoke host who needs a track separated tonight, or a producer who wants to test a stem split before committing to a DAW plugin purchase, the zero-friction entry point is the actual value.
The tool fits single-file, on-demand jobs well. It breaks under volume. The free processing quota is three files before a paywall appears, the per-file duration limit is 10 minutes, and the maximum file size is 100 MB. There is no API, so automation and batch processing are not possible regardless of tier. Teams that need to process a catalog, integrate separation into a pipeline, or run splits programmatically have to leave this tool entirely — the architecture does not support it. Self-hosting is also not an option, so teams with data residency requirements cannot use this service at all.
