In-room acoustic magnitude response smoothing via summation of correction signals

A method for smoothing acoustic magnitude response of an audio reproduction system in a room that preserves subjective impression of transient response and dynamics, comprising:

• a) selecting an in-room magnitude response passband lower frequency and an in-room magnitude response passband upper frequency;
• b) placing subwoofer and a user-positionable microphone in a room;
• c) energizing said subwoofer with an audio signal within said magnitude response passband and generating an acoustic output signal within said room;
• d) performing an in-room acoustic magnitude response analysis and determining whether an addressable room resonance induced peak associated with said acoustic output signal is detectable with said microphone, wherein a room resonance induced peak is regarded as addressable if said peak's magnitude exceeds a mean level through a passband or a prescribed sub-passband;
• e) and if an addressable room resonance induced peak is detected, then filtering a replica of the audio signal at the room resonance induced peak;
• and
• f) adding the filtered replica signal with the audio signal, whereby smoothing the room resonance induced peak is achieved, such that a subjective impression of transient response and dynamics of the audio signal are preserved.
