SirenMix

SirenMix offers a collection of practical audio tools for DJs who need to prepare tracks for a set. It's a website, so there's nothing to install. You just use the tools directly in your browser. This is for any DJ looking for a quick way to handle common prep tasks without opening a full digital audio workstation.

A key feature is that all audio processing happens on your computer. Your tracks are never uploaded to a server. This keeps your files private and makes the process fast. It's all done locally.

The site gathers several essential utilities in one place.

• Tempo and Key: Adjust the BPM or change the musical key of a track.
• Gain and Format: Normalize a track's volume or convert it to a different file format.
• Harmonic Mixing: Use an interactive Camelot wheel to find compatible keys for smooth transitions between songs. It shows all 24 keys and common moves.
• Audio Quality: Check aspects of your track's source quality.

SirenMix focuses on the day-to-day tasks that go into building a polished DJ set. The tools are designed to be straightforward and accessible for routine work.
