As a plug-in and stand-alone application, the Continuous Loudness Control (CLC) software features a unique visualization and patented loudness processing algorithm mainly developed for live applications.
Thereby, CLC can easily be operated. The target level for Loudness and upper limits for LRA and TruePeak have only to be set to get an excellent processing quality for common broadcasting signals. Additionally, the CLC software includes numerous operation modes for different fields of application.

  • Plug-in and stand-alone application for Mac® and Windows® systems
  • Dynamic loudness processing of unknown live audio and audio files to a given loudness target value with or without changing the original Loudness Range
  • Batch processing, extended audio format support (MXF) and expert mode for very special material

The Principle

CLC technology with the outstanding “Look-ahead Low Latency” algorithm allows users to constantly adapt the level of audio they are working on, against a given program-loudness value, along with a definable loudness range in real-time with all-time minimal obstacles without sonic discolorations. The CLC algorithm “learns” during processing about the dynamic structure and intention of the sound signal, and adopts its processing constantly to predict what comes next. CLC software is best for the dynamic processing of unknown Live audio, DAW audio, and audio files.

Batch Processing

But also broadcasters are kept in mind, as they receive many different types of audio files (e. g. MXF) and have to prepare them for transmission. Therefore, CLC‘s batch mode offers automated and unattended loudness analysis and processing of audio files. Incoming audio files from different sources are processed according to predefined settings for e. g. different genres; the output is stored in the target folder together with optional report files. Optimized presets and the Expert mode allow to better match requirements for different types of programs and distribution channels.
