Free Party Lab is a collection of free music and audiovisual tools built for DJs, producers and independent artists. We believe creative tools should be accessible to everyone, regardless of budget.
The name and spirit of the project come from our appreciation of free-party and DIY music culture: community, creativity, independence and access to music.
Exploring art through music should be easy for everyone. No paywalls, no cloud uploads, no hidden fees. Just open tools for DJs who care about their craft.
We believe that the best audio tools run locally on your machine, keeping your files private and your workflow fast. That's why every tool in Free Party Lab processes 100% in your browser.
Your audio files never leave your computer. There's no cloud storage, no analytics tracking, no data collection. When you use Free Party Lab, your files stay yours.
All processing happens in your browser using open web standards. Once a tool has loaded, converting and analyzing need no network at all.
Format Converter: Convert between MP3, WAV, FLAC, AAC, and OGG with control over quality settings. Encoding runs in your browser, up to 1 GB per file.
Spectrogram Analyzer: Visualize frequency content over time like professional desktop tools. Spot lossy transcodes, frequency cutoffs, and master quality issues instantly.
We're constantly adding new tools to make music production and DJ workflow easier.
Free Party Lab is built on open standards and leverages modern web technologies. While the project is not currently open source, we're committed to transparency and will continue expanding our toolset based on community feedback.
