Make anyone sing your song
The free vocoder makes anyone in a video sound like they’re singing the song of your choice. It’s a classic channel vocoder — your clip’s dialogue shapes the song so the music takes on its words — wrapped in a neon edge-glow look, all running in your browser.
No sign-up, no credits, and nothing leaves your device: the vocoding, the visual effect, and the MP4 export all run locally.

What is a vocoder?
A vocoder uses one sound to shape another. Here, your clip’s dialogue drives a song so the music seems to speak — or sing — the clip’s words, the classic robot / talk-box effect.

How to use the vocoder
What to feed it
The vocoder is only as clear as its inputs — these four things make the biggest difference.
Neon edge glow
Video inputs get a reactive neon outline that pulses with the audio — fully tunable, or off.

Tips for a clearer vocode
- Pair clear dialogue with a simple instrumental for the most intelligible result.
- Lower the band count for a chunkier, more robotic tone; raise it for clarity.
- Nudge pitch to fit the song’s key, then adjust depth and drive to taste.
- Turn the neon edge glow off for a plain render, or tune its radius and strength.
- Use the timeline to line up the clip and the song before exporting.

Vocoder — frequently asked questions
What does the vocoder do?
It makes anyone in a clip sound like they’re singing the song you choose — like turning a cartoon’s dialogue into a track. Under the hood it’s a channel vocoder: your clip’s dialogue shapes the song so the music takes on its words. It also wraps video in a neon edge glow — all in your browser, with an MP4 export.
What kind of song works best?
Use an instrumental with no vocals, and ideally something monophonic — a single, simple sound like a synth, organ, or lead. Busy, full mixes won’t clearly “sing” the words. The simpler and more sustained the sound, the more intelligible the result.
Is it really free?
100% free — no sign-up, no credits. All the vocoding, the edge-glow effect, and the export run locally on your device.
Does my video get uploaded anywhere?
No. Files you upload or record never leave your browser. The only time we touch a server is when you paste a link.
What can I export?
Video clips export to MP4 using a fast in-browser encoder (with an automatic fallback on browsers that can’t encode it). Audio-only inputs export a WAV.
What is a channel vocoder?
It analyzes one sound (your clip’s dialogue) across frequency bands and uses that to shape another (the song), so the song takes on the rhythm and articulation of the speech — the classic robot/talk-box effect.
