The KARMAudioAU Loudness Control Plug-In from Leader provides automatic control of perceptual loudness and true-peak using ITU-R BS.1770 multi-channel loudness and true-peak estimation algorithms, EBU R128 gating (optional), and proprietary correction algorithms to ensure compliance with ATSC A/85, EBU R128, and short-term peak loudness and peak-program level requirements. The KARMAudioAU continuously monitors embedded stereo or multi-channel surround audio loudness and seamlessly adjusts system gain across all channels to maximize impact, while achieving the target loudness and preserving the spatial imaging.
The KARMAudioAU performs 8x over-sampling true-peak estimation and instantaneous correction to all stereo or multi-channel surround channels to ensure adherence to per channel peak-program level limits. The KarmaAudioAU eliminates failures and ensures maximum use of the available loudness.
