Sound Wave Extractor

Vocal isolation (also known as source separation) is the process of extracting the vocal track from a mixed audio recording. Our tool uses advanced digital signal processing and AI-inspired filtering techniques to separate the frequency ranges typically occupied by human vocals (roughly 200Hz–4000Hz) from the instrumental elements, delivering clean vocal and backing track outputs.

We support a wide range of audio formats including MP3, WAV, FLAC, OGG, M4A, and AAC. The maximum file size is 100 MB. For best results, we recommend using high-quality source files (256kbps or higher for MP3, or lossless formats like WAV/FLAC).

Yes! Our Sound Wave Extractor is completely free with no hidden fees, no credit card required, and no sign-up necessary. You can extract vocals and instrumentals as many times as you want. We believe powerful audio tools should be accessible to everyone—musicians, producers, content creators, and hobbyists alike.

Your privacy is our top priority. All audio processing happens directly in your browser using local Web Audio API technology. Your files are never uploaded to any server, meaning no third party ever has access to your audio. You can use this tool with complete confidence, even with sensitive or unreleased material.

The maximum file size is 100 MB. There is no strict limit on audio length, but files longer than 30 minutes may take more time to process. For optimal experience, we recommend files under 15 minutes. Supported sample rates include 44.1kHz, 48kHz, and 96kHz.

Our tool uses optimized frequency-domain filtering that works well for most modern music recordings. The quality depends on the source material—tracks with clear, centered vocals and well-mixed instrumentals yield the best results. While not a full deep-learning solution, our processing provides impressive separation suitable for remixing, karaoke creation, sampling, and audio analysis.

You are free to use the extracted audio for personal projects, remixes, karaoke, and creative work. However, for commercial use, please ensure you have the appropriate rights to the original recording. Copyright laws still apply to the source material—our tool is a processing utility, and the legal responsibility for usage rests with the user.
