About LA STUDIO

Democratizing music production with AI. No installation, no account required — professional audio processing with free core tools.

Our Mission

LA Studio was built with a simple belief: professional audio tools should be accessible to everyone. Traditionally, vocal removal, stem separation, and audio mastering required expensive software, powerful hardware, and technical expertise. We set out to change that.

By leveraging cutting-edge browser technologies like WebGPU and ONNX Runtime Web, we bring state-of-the-art AI models directly to your browser. There is nothing to install, core processing stays in your browser, and the core tools are free to use. Whether you are a musician creating a remix, a podcaster cleaning up audio, or a student learning about audio production, LA Studio gives you the tools you need.

Free Core Tools

Standard separation, noise removal, and BPM analysis are free. Autotune and some other tools have free-use limits; HQ and generation features have plan or credit conditions. Check the price shown before running and the pricing page.

Privacy First

Standard separation, noise removal, and BPM analysis run in your browser. HQ separation, music/loop generation, reference mastering, OCR, and cloud saving send inputs or audio to servers according to the feature you choose.

No Sign-up Required

You can try Standard separation without an account. Cloud saving and some generation or paid features require login.

Features

LA Studio offers a comprehensive suite of AI-powered audio tools designed for musicians, producers, content creators, and audio enthusiasts.

Vocal Remover

Separate vocals from instrumentals with AI. Create karaoke tracks or isolate acapella instantly.

Stem Separation

Split any song into 6 individual stems: drums, bass, vocals, guitar, piano, and other.

Noise Removal

Remove background noise, hum, and unwanted sounds using advanced AI denoising.

AI Mastering

Professional loudness optimization, EQ, and compression for studio-quality output.

DAW Editor

Full-featured multi-track audio editor with timeline, mixer, effects, and MIDI support.

BPM Detection

Automatically detect the tempo and musical key of any audio track.

Technology

Desktop Chrome or Edge is recommended. Features depend on GPU, memory, and browser. Test a short file first, including on mobile devices.

WebGPU

Hardware-accelerated GPU compute for AI inference directly in the browser.

ONNX Runtime Web

Runs neural network models natively in the browser with WASM and WebGPU backends.

Web Audio API

Low-latency audio processing, playback, and real-time effects chain.

IndexedDB

Client-side model caching for fast loading after the first visit.

WebAssembly

Near-native performance for DSP operations and audio encoding.

React + TypeScript

Modern, type-safe UI framework powering the entire application.

How It Works

These steps describe Standard browser audio processing. First use may require a model download. Cloud features use a separate processing path.

Upload: Select or drag-and-drop your audio file. It stays in your browser's memory.
Process: The AI model runs on your GPU (via WebGPU) or CPU (via WebAssembly), processing the audio entirely on your device.
Download: Preview the result and save the audio you need. Choosing cloud saving uploads data to a server.

Open-Source AI

LA Studio is powered by state-of-the-art open-source AI models from the research community. We are grateful to the researchers and developers who make their work freely available, and we are committed to contributing back to the open-source ecosystem. The specific models used include architectures optimized for music source separation, noise reduction, and audio analysis.
