Methods and apparatus for recreating audio signals to sound as though the signals had been recorded in a different acoustic environment is provided. The methods and apparatus may include one or more inputs that receive an audio signal and an input that receives a selected acoustic environment signal, as well as processing circuitry that produces one or more output signals representative of the audio signal being played in the selected acoustic environment. The input, output and characterization signals may be processed and recorded to storage media, either individually or together. The circuitry may interface with other technology and circuitry or may be a complete stand-alone system.
