A new dynamic processor- plugin has been releases by Sonic Anomaly for free – Unlimited
Unlimited is a loudness maximizer and limiter for stereo and 5.1 surround material. It also offers an ITU-R BS.1770 compliant loudness meter in addition to RMS output meters.
Unlimited aims to have balanced characteristics: avoiding audible distortion typical to hard limiting and clipping to the extent it is feasible, yet still not sounding compressed or vigorless.
Even though it supports 5.1 configuration, normal stereo operation is fully supported and the additional channels won’t consume any CPU when they are not in use.
