AI Vocal Remover

About AI Vocal Remover

This AI-powered vocal remover uses deep neural networks to separate vocals from music with professional quality. Unlike simple phase cancellation methods, our AI model understands audio patterns and can cleanly isolate vocals even in complex mixes. Processing happens entirely in your browser using WebGPU/WebGL acceleration - your audio is never uploaded to any server.

How does AI vocal removal work?

Our tool uses a trained deep neural network that has learned from thousands of songs to recognize and separate vocal patterns from instrumental music. The AI processes the audio in the frequency domain using Short-Time Fourier Transform (STFT), predicts the instrumental components, and then extracts vocals by subtraction. This approach is far more accurate than traditional phase cancellation methods.

When does the AI model download?

The AI model (~68MB) downloads automatically when you click 'Separate Audio' for the first time. This keeps the page loading fast while ensuring the model is ready when needed. Once loaded, the model stays in memory for your session, so subsequent files process faster. All processing happens in your browser - your audio never leaves your device.

What is WebGPU vs WebGL?

WebGPU is a modern graphics API that provides faster neural network processing. If your browser supports WebGPU (Chrome 113+, Edge 113+), the tool will use it for best performance. Otherwise, it falls back to WebGL which is slower but widely supported. Processing time depends on your hardware and the backend used.

What audio and video formats are supported?

All common audio formats are supported including MP3, WAV, OGG, AAC, M4A, FLAC, OPUS, and more. Video files are also supported - the tool will automatically extract the audio track from MP4, MKV, AVI, MOV, WebM, and other video formats. The AI model works with both mono and stereo audio. For stereo files, both channels are processed separately for best results.

How long does processing take?

Processing time depends on your hardware, the audio length, and which backend (WebGPU/WebGL) is used. With WebGPU on a modern GPU, a 3-minute song typically takes 30-60 seconds. With WebGL, it may take 2-3 times longer. Longer songs are processed in chunks, with progress shown in real-time.

What are the different separation modes?

There are three modes:
1) Extract Vocals Only: Gets just the vocal track (acapella) - great for sampling or remixing
2) Extract Instrumental Only: Removes vocals to create a karaoke/backing track
3) Extract Both: Outputs both tracks - recommended if you need both versions

Is the separation quality good?

AI-based separation provides significantly better quality than traditional phase cancellation. Most commercial songs will have clean vocal isolation with minimal artifacts. Results are best for:
- Modern pop, rock, electronic, hip-hop with clear vocal recordings
- Songs mixed at professional studios
- Tracks with distinct vocal vs instrumental sections

Quality may vary for:
- Live recordings with heavy reverb
- Songs with many layered vocals
- Very old or low-quality recordings

What output format do I get?

The tool outputs WAV format at the same sample rate as your input file (typically 44.1kHz or 48kHz stereo). This maintains maximum quality from the separation process. You can convert to MP3 or other formats afterward if needed.

Is my audio file safe and private?

Your audio file never leaves your device. All AI processing happens directly in your browser using TensorFlow.js. No audio data is uploaded to any server. Once you close the page, all data is cleared from memory.

Can I use this for commercial purposes?

The tool itself is free to use, but you must respect copyright laws. Extracting vocals or instrumentals from copyrighted songs doesn't give you rights to use them commercially. Only use extracted audio if:
1) You own the rights to the original recording
2) You have permission from the copyright holder
3) Your use falls under fair use provisions
4) The song is in the public domain

What's the maximum file size?

The maximum file size is 100MB. For best performance, we recommend files under 50MB or songs under 5-6 minutes. Longer files require more memory and processing time. If you have a very long audio file, consider splitting it into smaller segments first.

The tool is slow or crashing. What can I do?

If you experience slow processing or crashes:
1) Close other browser tabs to free up memory
2) Use Chrome or Edge for best WebGPU support
3) Try shorter audio files first
4) Ensure your browser is up to date
5) On mobile devices, processing will be slower - desktop/laptop is recommended
6) If using WebGL fallback, expect longer processing times
