🎵 Audio Splitter

Professional AI-powered audio stem separation for musicians, producers, and audio engineers.

Effortlessly separate vocals, drums, bass, piano, and other instruments from any audio or video file using state-of-the-art AI technology powered by Meta's Demucs model.

⚡ Key Features

• AI-Powered Precision — Built on Meta's state-of-the-art Demucs models for professional-grade audio separation.
• 100% Offline — No uploads, no servers, no privacy risks. All processing happens locally on your machine.
• Flexible Separation Models — Choose between 2-stem (Vocals/Instrumental), 4-stem (Vocals/Drums/Bass/Other), or 6-stem (adds Piano/Guitar) configurations.
• Performance Presets — Select from Fast (preview), Standard (balanced), or High Quality (fine-tuned) modes to match your workflow.
• Interactive Stem Player — Listen to, solo, or mute individual stems in real-time with an integrated waveform visualizer.
• Multi-Format Support — Instantly processes audio and video files including MP3, WAV, FLAC, MP4, MKV, and MOV.
• Selective Export — Export specific tracks (e.g., just the vocals) or batch export all stems in WAV (lossless) or MP3 formats.
• Smart Resume — Cancel and restart processing securely with intelligent temporary file management and cleanup.
• Persistent Preferences — Automatically saves your model choices, export paths, and output settings for a streamlined workflow.

⚡ How It Works

1. Import Media Drag and drop any audio or video file into the application. The app automatically detects tracks and prepares the file for separation.
2. Select Configuration Choose your desired stem count (2, 4, or 5 stems) and quality preset (Fast, Standard, High Quality).
3. Process Locally The AI engine runs directly on your device, splitting the customized tracks without ever sending data to the cloud. You’ll see real-time progress for extraction and separation.
4. Preview & Refine Use the built-in player to solo specific instruments (like hearing only the bass) or toggle vocals off to check the instrumental.
5. Export Select which stems to save—export just the drum track for sampling, or dump all stems for a full mix session.

⚡ Use Cases

• Musicians & Vocalists Create instant backing tracks for karaoke or practice by removing vocals from your favorite songs.
• Producers & Remixers Sample isolated drums, basslines, or melodies to flip into new beats without frequency masking.
• DJs Generate custom acapellas and instrumentals for live mashups and transitions.
• Audio Engineers Analyze professional mixes by inspecting individual layers or extract specific elements for restoration.
• Content Creators Quickly separate dialogue from background music in video clips for cleaner editing or repurposing.
• Music Educators Isolate specific instrument parts to help students hear and learn complex solos or rhythm patterns.
