About This Tool

Purpose and use case: converts stereo songs into karaoke-ready backing tracks by attenuating centered vocals, enabling singers, educators, and content creators to practice with instrumentals.
Core processing combines center-channel removal (phase cancellation) with spectral adjustments and optional ML-based separation when available. Users can set vocal_removal_strength (0–100), select output format (MP3 or WAV), and optionally adjust tempo or pitch. Processing handles long tracks by chunking while preserving instrumental integrity.
Benefits include faster turnarounds and file-based privacy for sensitive or proprietary material. Results vary by mix, mastering, and stereo width. The tool is not a substitute for professional mastering and does not provide lyrics, licensing, or video features.

Frequently Asked Questions

Find Quick Answers

Can vocal removal be perfect?

No. Most mixes place vocals in the center; phase cancellation may also affect centered instruments. Expect residual vocals or artifacts. For best results, use tracks with clearly centered vocals and moderate mastering.

What input/output formats are supported?

Input supports MP3 and WAV; output supports MP3 and WAV with 44.1–96 kHz sampling. Bitrate quality depends on chosen format; high-bitrate outputs yield better instrumental fidelity.

Do tempo/pitch adjustments affect quality?

Adjustments are applied after vocal removal. Moderate tempo or pitch shifts preserve instrumental integrity; extreme shifts can introduce artifacts or reduce tonal clarity.

Are there licensing considerations?

Generated instrumentals may still be subject to copyright. Ensure you have rights to use the original track; the tool does not grant licensing or distribution rights.
