The new VST-3 BroadcastSafeAudio plug-in for loudness measurement on professional audio workstations has been announced.
Eyeheight said BroadcastSafeAudio provides automatic real-time measurement of perceptual loudness and true-peak level using ITU-R BS.1770 multi-channel loudness and true-peak estimation algorithms. These are coupled with the ability to correct the level to the target loudness. EBU mode is supported and logging provided.
Embedded stereo or surround audio loudness are continuously monitored and displayed graphically. System gain can be adjusted across all channels to maintain the target loudness while preserving the audio imaging. BroadcastSafeAudio also performs 8x oversampling true-peak estimation and instantaneous correction on all stereo or surround channels, ensuring adherence to all peak-programme level limits.
BroadcastSafeAudio is based on the Steinberg Virtual Studio Technology (VST) software interface and is therefore compatible with a very wide range of IT-based audio recording and editing systems, said Eyeheight. It provides the audio compliance features developed for Eyeheight’s established KARMAudioAU which is designed for use with Apple Final Cut Pro 7.
