Youlean Loudness Meter measures LUFS (integrated, short-term, momentary), true peak levels, and loudness range. It includes presets for Spotify, YouTube, Netflix, and TV broadcast, so you can check your loudness target before uploading. The free version is not a stripped-down demo. You get accurate measurements, real-time loudness graphs, and historical data. The interface is resizable and has a mini view for keeping it visible without eating up screen space.
If you’re putting music on streaming platforms, you need a loudness meter. Youlean is the best free option, and it’s not even close.
