Music Gear Review: RTW Continuous Loudness Control

RTW's Continuous Loudness Control (CLC) software comes in both standalone and plug-in versions for either Macs or PCs. CLC allows you to adjust the loudness level of mono to 5.1-channel program audio against a selectable program-loudness standard such as EBU R128, ITU BS.1771, ATSC A/85 and others.

CLC is not a broadband or a multi-band system dynamics processor with the typical threshold, ratio, attack and release time parameters. The patented Adaptive Morphing Technology continuously synchronizes its time and frequency response with the signal itself and offers minimal unwanted sonic artifacts when setting a target loudness range.

Rather than sets of specific parameters grouped as presets, CLC offers numerous operation modes separated into categories describing the intrinsic nature of the program. CLC uses a “look ahead low latency” algorithm to allow loudness correction to a specific target without changing the original Loudness Range. It has an adjustable True Peak limiter and improved audio metering and monitoring facilities.

The standalone version CLC has the same GUI except that I could open interleaved stereo (or multi-channel surround) audio files directly into a window in the GUI.

RTW’s Continuous Loudness Control software includes both the plug-in and standalone versions and sells for $899 MSRP.
