Hi Product Hunt! I’m Philippe, the creator and maintainer of LUFScale.
LUFScale is a free and open-source desktop application for macOS and Windows that analyzes and normalizes perceived audio loudness using LUFS and True Peak. It can analyze files without changing them, normalize audio to a chosen target, or write ReplayGain metadata.
It supports MP3, FLAC, WAV, AIFF, M4A, OGG and Opus, with before-and-after comparison, CSV reports and interrupted-job recovery. Original files are never moved or modified, and the source code is available on GitHub under GPL-3.0-or-later.
I’d be grateful for your feedback, particularly about the workflow and the measurements or reports you would like to see in future versions. Thank you for taking a look!
