Claim:
1. Apparatus for determining a measure for a perceived level of reverberation in a mix signal comprising a direct signal component and a reverberation signal component, comprising: a loudness model processor comprising a perceptual filter stage configured for filtering the direct signal component to acquire a filtered direct signal, and configured for filtering the reverberation signal component to acquire a filtered reverberation signal, wherein the perceptual filter stage is configured for modeling an auditory perception mechanism of an entity a loudness estimator configured for estimating a first loudness measure using the filtered direct signal and configured for estimating a second loudness measure using the filtered reverberation signal; and a combiner for combining the first loudness measure and the second loudness measure to acquire the measure for the perceived level of reverberation.
