Claim:
1. A system for loudness-based audio-signal compensation, comprising: (a) an input line that accepts an input audio signal; (b) a loudness estimator, coupled to the input line, that processes the input audio signal to obtain an audio playback loudness level and that also provides a production loudness level for the input audio signal; (c) a filter generator/selector coupled to an output of the loudness estimator that provides an audio compensation filter based on the production loudness level and the audio playback loudness level, wherein the input signal is processed by the audio compensation filter to provide an output signal, and wherein when the loudness estimator obtains at least one of a new audio playback loudness level or a new production loudness level for the input audio signal, the filter generator/selector provides a new audio compensation filter which is then used to process the input signal in order to provide the output signal.
