Continuous Loudness Control Stereo from RTW is a plugin or standalone software for automated adjustment of the loudness of stereo audio files. It is used by home users and professionals alike who want to quickly edit unknown or long audio files in terms of volume, for example in the postproduction of live audio files, DAW audio and broadcast preparation for TV and radio. It differs from "Continuous Loudness Control" by its limitation to only two channels. Thanks to its design as standalone software instead of just a plug-in, CLC can also be used without a host application, allowing the software to be used in third-party application environments without any additional DAW software.
