Ultimate Vocal Remover in your browser — no install, plus the chords.
UVR is a powerful desktop app. If you'd rather not download, install and configure it, ChordSonic removes vocals and splits stems right in the browser — then finds the chord progression, key and tempo.
The short answer.
If you want unlimited, fully offline separation with deep control over models and settings — and you're happy to install and run a desktop app — UVR is excellent and free. It's the power-user pick for a reason.
ChordSonic is the better fit when you want a result in two clicks with nothing to install, on whatever device you're on, and when you want the chords as well as the stems — the chord progression, key and tempo, ready to transpose and export.
It's full local control vs zero setup plus a chord chart. Plenty of people keep both around.

Three reasons we hear over and over.
- 01
You don't want to install and configure a desktop app
UVR means a download, an install, and — for good speed — sorting out a capable GPU. ChordSonic skips all of it: open the page, upload, download the result.
- 02
You're on a phone, Chromebook or work machine
Anywhere you can't install software, a desktop tool is a non-starter. ChordSonic runs in the browser, so the same workflow works on a locked-down laptop or a phone on the couch.
- 03
You want the chords, not only the stems
Once the vocal is gone, ChordSonic keeps going — it reads the chord progression, key and tempo off the track and lets you transpose and export them. A separator stops at the audio.
Frequently asked
Is ChordSonic free like Ultimate Vocal Remover?
UVR is free and open-source, with no usage limits because it runs on your own machine. ChordSonic is free to use with a daily separation quota and no signup, plus a paid tier in the works for heavier use. The reason to pick ChordSonic isn't price — it's that there's nothing to install and you also get the chords.
Do I need to install anything?
No. ChordSonic runs entirely in the browser — upload a track and download the result. UVR is a desktop application you download and install, and it runs separation models locally (a capable GPU helps a lot). If you'd rather not set any of that up, ChordSonic is the no-install option.
Is UVR better quality?
UVR gives power users control most web tools don't — you can choose among different local models and tune parameters per track, which can win on tricky material. ChordSonic ships one tuned pipeline with no knobs. Separation quality depends heavily on the source, so the honest answer is to try both on your actual file.
Does ChordSonic give me the chords too?
Yes. After it isolates the instrumental, ChordSonic detects the full chord progression, key and tempo and puts them on a timeline you can transpose and export to TXT, CSV or JSON. UVR is a separation tool and doesn't do chord detection.
Can I run it on a phone or a locked-down work laptop?
Yes — because it's browser-based, ChordSonic works on a phone, tablet, Chromebook or a machine where you can't install software. UVR needs a desktop OS and an install, so those environments are exactly where a web tool fills the gap.
Skip the install. Remove vocals in the browser.
Drop an MP3 or WAV, get a clean instrumental — and the chord progression, key and tempo with it. Nothing to download.
