Disclosed are systems and methods for enhancing playback of an audio signal to approximate the listening experience at a recording site. A test signal is emitted into a recording environment and acoustic parameters for the recording environment are calculated according to the test signal and a response to the test signal. An encoded signal including a recording of an audio event in the recording environment and the acoustic parameters is then transmitted to a listening site or affixed to a medium. At the listening site the acoustic parameters are extracted and the recording is enhanced or corrected according to the acoustic parameters. Acoustic parameters for the listening site may also be calculated and the recording may be further enhanced therewith. During playback of the enhanced recording, the sound may be measured and the enhanced recording may be actively enhanced during playback according to the measurement.

System and method for transmitting environmental acoustical information in digital audio signals

A method and apparatus is described for electronic signal monitoring and conversion to differing form. The preferred embodiment includes automatic selection of an audio signal from a plurality of input signals which may be in differing form, and conversion and processing of the selected signal to place it into one or more desired form to be output for further use. Further operations include delaying and mixing a plurality of signals may take place automatically or under operator control. Visual and/or audible monitoring of the signal(s) is also shown.
