TC Electronic LC2 - Stereo Loudness Corrector — Free Download

Purpose and Compliance

LC2 is designed to prepare audio for loudness-compliant delivery across streaming, broadcast, film, podcasts, and online platforms. It simplifies the technical process of loudness normalization without sacrificing sound quality. The software adheres to major broadcast standards, including ITU BS.1770.4, ATSC A/85, EBU R128, TRB32, and OP59, ensuring your material meets industry expectations.

It operates as an AAX AudioSuite plug-in within Pro Tools or as a standalone application that supports batch processing. The processing is offline, two-pass, and faster than real-time, allowing you to hit precise loudness targets efficiently. This dual approach gives you flexibility whether you’re working inside a DAW or handling multiple files outside it.

Key Capabilities

LC2 includes a Brickwall 2 True Peak Limiter with profiles and linking functionality, providing mastering-quality peak limiting. This ensures your output passes loudness and true peak requirements across different platforms. The integrated limiter helps maintain musical dynamics while preventing overs, giving you confidence in your final files.

A Short Term Max Limit setting allows you to keep promos and short-form content compliant with the latest broadcast standards. The software also features visual indicators: traffic light colored statuses for source and processed files, plus a dual loudness landscape radar that displays the original and normalized audio side by side. This gives you a quick graphical check that processing was successful.

Workflow and Batch Processing

The standalone application supports drag-and-drop audio files into a watch folder on your computer or network. You can place multiple files for automatic batch processing, which generates peak-limited, loudness-normalized files with consistent quality. The software automatically modifies file names to indicate processing settings and any warnings, making it easy to track your outputs.

This workflow is ideal for high-volume tasks, such as delivering multiple episodes or tracks. You set your loudness target and true peak limits, drop files into the watch folder, and let LC2 handle the rest. The visual status indicators help you quickly identify any files that may need attention, allowing you to correct inputs or settings without guesswork.

Practical Applications and Integration

LC2 is suited for post-production houses, podcast editors, music producers, and broadcast engineers who need consistent loudness compliance. In Pro Tools, you can use the AudioSuite version to process individual tracks or entire sessions offline, ensuring each clip meets loudness targets before final delivery. The standalone mode is handy for file-based workflows, such as preparing masters for streaming services or creating broadcast-ready WAVs.

The limiter profiles and linking help you match specific platform requirements, and the Short Term Max limit is particularly useful for promos and ads that must adhere to strict momentary loudness caps. Whether you’re delivering a podcast episode, a commercial, or a film mix, LC2 streamlines the technical side so you can focus on creativity.
