How it works

Four steps from raw audio to finished karaoke video – all on your machine, no internet required.

01

Drop your audio

Load any MP3, WAV, FLAC, or M4A. Drag it straight into the app – no format wrangling, no preprocessing.

02

AI separates & transcribes

BS-RoFormer isolates the vocals from the mix. Whisper transcribes every word with precise per-word timing.

03

Edit & refine

Fine-tune word timing, correct transcription errors, and insert any missing or spoken lyrics before export.

04

Export your video

Render a full HD karaoke video with synchronized lyric wipes – ready to play, share, or host.

What it does

Everything a karaoke studio can do

The full pipeline – AI separation, transcription, editing, and video export – in a single Windows app.

Runs entirely on your PC

All AI processing happens locally. Your audio never leaves your machine – no accounts, no uploads, no cloud dependency of any kind.

State-of-the-art vocal separation

Powered by BS-RoFormer – the most accurate open-source vocal isolation model available. Clean stems, every time.

Timing tools other editors lack

Drag-to-select words for batch edits, magnetic auto-resize of adjacent words, tap-to-align on playback, distribute-evenly across gaps, frame-level nudging, and per-word confidence indicators.

Lyric editing built for hard cases

Ghost-preview copy-paste from anywhere in the song, insert missing phrases with auto-timing estimation, AI lyric correction, distribute-evenly spacing, and full undo/redo across all edits.

GPU-accelerated processing

NVIDIA CUDA support for fast inference. Automatic CPU fallback ensures every Windows machine can produce results.

Whisper transcription

OpenAI Whisper handles transcription. Catches lyrics that manual entry and simpler tools consistently miss.

Full HD video export

Full HD (1920×1080) MP4 with animated wipe-style lyrics, an instrumental-only audio track, and frame-perfect sync. Compatible with TVs, tablets, and karaoke hardware.

One-time purchase

$49.99, purchased and activated directly in the app. No subscription, no renewal – pay once and produce unlimited karaoke videos.
