Our verdict on Klangfreund LUFS Meter

Klangfreund LUFS Meter is an audio plug-in for musicians, producers, audio professionals, and videographers who need real-time loudness measurement and adjustment. It measures integrated loudness using ITU-R BS.1770, along with momentary, short-term, and true-peak values. Loudness bars, numeric readings, and a loudness history graph support monitoring while working in a compatible host. The plug-in supports AU, VST, VST3, and AAX formats, with experimental Linux support, and works on Windows and macOS.

Pricing is straightforward, with two one-time editions. Discounted LUFS Meter costs USD 19 and includes core loudness measurement and adjustment, plus up to six synchronized instances. LUFS Meter costs USD 39 and adds the full feature set, commercial usage, unlimited synchronized instances, and 32 synchronization groups. A free demo provides measurements for sessions shorter than one minute and has a 30-day trial period. EU VAT may be added to listed prices. The lower-cost edition is intended for personal, non-commercial, or qualifying small commercial use, while the standard edition is the clearer choice for unrestricted commercial work.

Its strongest focus is loudness control rather than broad audio analysis. Manual and automatic loudness adjustment, international loudness specifications, presets, customizable startup settings, and synchronized plug-in instances make it suited to matching tracks and monitoring multiple channels during mixing. The two-channel capacity and lack of offline file analysis limit its role for larger multichannel workflows or batch-oriented review. Choose Klangfreund LUFS Meter when real-time standards-based metering and a low one-time price matter most. Choose an alternative when you need offline analysis, broader channel capacity, or a wider analysis suite.
