Find the right take.
One song. A different voice. Every version worth comparing.
Source track
Drop an audio file here, or choose one below.
Already have separated stems?
Upload both to reuse your own separation. Preview times refer to the original track.
Start with an excerpt
Try a verse or chorus before spending time on a full render.
Separation is cached. Each take keeps its recipe.
Voice & recipe
Convert with a community voice model and optional retrieval index.
Retrieval index
Use a clean, isolated voice clip. Seed-VC uses the first 25 seconds.
Without an index, this is sent as 0.
Fine-tune & mix
Connect your worker to start a take.
Compare a few settings
Queue up to three excerpts with one parameter changed. Stems are reused.
Recent takes
Listen first. Technical checks catch issues, not musical taste.
Upload a track, choose a voice, and render an excerpt.
Takes
Your renders, recipes, and listening notes.
Your studio setup
Cloudflare at the front. Your PC does the heavy lifting.
Worker connection
Your audio, models, and renders live on the worker. Keep the PC and its tunnel running while rendering.

Available engines
Install the engines you want to use. Seed-VC takes a reference recording; RVC takes a trained community model.
Engine availability appears when your worker connects.
First song workflow
Start small, keep a baseline, and listen for the differences.
- Install an engine
Start with Seed-VC and a clean reference, or RVC with a model and its matching index.
- Test a 20-second excerpt
Choose a part with sustained notes and consonants. Reuse separated stems between takes.
- Compare before rendering
Check artifacts, diction, pitch, and voice character. Save notes and a favorite, then render the full track.
Check the audio path
A synthetic tone can verify uploads, remixing, measurements, and downloads before models are installed.
This creates a generated test signal. It does not run voice conversion or demonstrate voice quality.
Session
Local access or a protected Cloudflare session.
