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

A method for enhancing audio signals comprising:

• emitting a playback test signal in a playback environment;
• recording a response to the playback test signal;
• extracting playback acoustic information according to analysis of the test signal and the recorded response;
• extracting recording acoustic information from multiple tests of various frequencies and levels from an encoded signal;
• extracting an audio signal from the encoded signal;
• correcting the audio signal according to the recording acoustic information and the playback acoustic information;
• and
• audibly presenting the corrected audio signal in the playback environment using a speaker system.

A system for enhancing audio signals comprising one or more processors and one or more memory devices operably coupled to the one or more processors, the one or more memory devices storing executable and operational data effective to cause the one or more processors to:

• transmit multiple recording test signals of various frequencies and levels to at least one speaker in a recording environment;
• receive from at least one microphone a response of the recording environment to the recording test signals;
• extract recording acoustic information according to analysis of the recording test signals and the responses thereto;
• receive from at least one microphone a sound recording of an audio event in the recording environment;
• and
• generate an enhanced signal including both an audio signal corresponding to the sound recording and the recording acoustic information.

• transmit a playback test signal to at least one speaker in a playback environment;
• receive from one or more microphones a measured response of the playback environment to the playback test signal;
• extract playback acoustic information according to analysis of the test signal and the recorded response;
• receive an encoded signal;
• extract recording acoustic information from multiple tests of various frequencies and levels from an encoded signal;
• extract an audio signal from the encoded signal;
• correct the audio signal according to the recording acoustic information and the playback acoustic information;
• and
• transmit to the at least one speaker in the playback environment the corrected audio signal.
