Free AI Vocal Remover – Remove Vocals Online | Tunii

What

Tunii is a browser-based AI audio processing tool designed to separate vocals, generate instrumental tracks, and isolate individual instrument stems from mixed audio recordings. It targets vocalists, music educators, DJs, producers, and video creators who require backing tracks, acapellas, or isolated arrangements for practice and production. Positioned as an accessible utility with a credit-based model, it offers a non-subscription alternative to complex audio editing software.

Features

• AI Vocal and Instrumental Separation: Splits mixed audio files into independent instrumental and isolated vocal tracks for karaoke, rehearsal backing tracks, and remixing.
• Multi-Track Stem Extraction: Isolates individual instrument components, including drums, bass, piano, and guitar, allowing musicians and teachers to analyze and practice complex arrangements.
• Multi-Format Processing and Export: Supports MP3, WAV, M4A, and FLAC uploads up to 100 MB or 10 minutes in length, with lossless WAV and FLAC downloads unlocked via purchased packs.
• Exact-Duration Credit Accounting: Deducts processing credits to the exact second of source audio duration and automatically restores minutes to the balance if a processing job fails.

Helpful Tips

• Evaluate Source Mix Complexity: AI separation yields the cleanest results on dry studio recordings; tracks featuring heavy reverb, overlapping vocal layers, or dense live mixes should be previewed carefully before deployment.
• Match File Formats to Use Cases: While standard MP3 exports suffice for casual practice and basic listening, music production and DJ work typically require paid packs to access uncompressed WAV or FLAC exports.
• Verify Licensing Before Derivative Use: The platform does not confer copyright clearance, meaning users must ensure they hold proper permissions before using extracted vocals or stems in public remixes, dance choreography, or commercial video edits.

OpenClaw Skills

Tunii currently documents no native integrations, webhooks, or public API endpoints. In a hypothetical implementation within the OpenClaw ecosystem, an OpenClaw agent could interface with Tunii to automate pre-production media pipelines—for example, automatically dispatching uploaded audio files for stem extraction and delivering separated vocal and instrumental stems directly to downstream video editing or mastering workflows. This hypothetical agent-led automation could reduce manual asset prep time for digital creators and audio engineering teams.
