The L-Normalizer is an affordable, cross-platform loudness normalization tool designed to assist audio engineers in post production and broadcasting environments. It builds on the capabilities of previous loudness meter applications, offering a streamlined workflow that enhances audio material by analyzing and adjusting loudness levels to meet professional standards.

This application provides two primary workflow steps: analyzing the audio material and rendering the improved version. Users can normalize their audio based on either program loudness or short term loudness, making it suitable for both longer tracks and shorter clips under 30 seconds. The integrated True Peak Limiter includes customizable options such as variable knee width and release time, ensuring that audio peaks remain controlled and free from distortion.

Available as VST, AU, and AAX plugins, the L-Normalizer fully complies with international loudness standards including BS-1770 (rev.3), EBU R128, and ATSC A/85. It supports mono, stereo, and 5.1 channel formats with automatic track detection and offers both offline and real-time processing capabilities. The True Peak Limiter guarantees no clipping occurs even during positive gain normalization, making this tool essential for maintaining consistent loudness and audio quality across various media platforms.
