YT Levelr

An extension that automatically equalizes the volume of YouTube videos, especially podcasts where every producer has their own idea of what the correct levels should be.

Features

Automatic Loudness Normalization: Automatically adjusts audio levels between videos to create a consistent listening experience

Smart Gain Management: Uses asymmetric gain limits (more aggressive cuts than boosts) to prevent sudden loud blasts

Confidence-Based Adjustment: Gradually widens gain range over 30 seconds as confidence in measurement grows

Drift Correction: Slow automatic correction every 3 minutes after lock to handle long-term level shifts
