Audio Normalization

The Audio Normalization task analyzes an audio track's loudness profile using the industry-standard EBU R128 specification.

Instead of guessing volume adjustments, it measures the integrated loudness and true peak of the track to generate a precise mathematical filter string. This filter is then passed back to your encoding pipeline to balance the track, ensuring your media plays back at consistent, standard volume levels without audio clipping or distortion.

This task is specifically built to support the FFmpeg Builder: Audio Normalization flow element.


Configuration Settings

Concurrent Tasks

  • Description: The maximum number of audio normalization analysis tasks that can run simultaneously.
  • Usage: Loudness analysis scans raw audio data sequentially. Because this process is fast and relies on highly optimized parsing utilities rather than heavy video transcoding or AI models, it can safely be left at its default value (4) to process multiple audio tracks concurrently without performance hits.

Why Use Audio Normalization?

  • Offload Analysis Pipelines: Reviewing audio tracks for loudness compliance requires a full file scan. Offloading this initial measurement pass to the central Forge processor keeps your active processing nodes free to maintain high-throughput transcoding tasks.
  • Perfect Multi-Pass Adjustments: This task handles the intensive "first pass" analysis, mapping out the audio profile completely. It provides the FFmpeg Builder with a precise loudnorm configuration string so the actual processing node can instantly apply a perfect, linear loudness adjustment during the file rewrite phase.
