Adaptive crosstalk rejection

A computer program for reducing crosstalk in an audio-listening channel, the computer program product comprising:

• a non-transitory computer readable medium comprising code configured to cause a computer to:
• detect a first audio-listening channel and a second audio-listening channel;
• transmit from a first signal source a first input signal to a first amplifier associated with a first audio-listening channel;
• measure a signal level along at least a portion of a common path shared by the first audio-listening channel and a second audio-listening channel, wherein the common path includes at least some resistance;
• determine a digital compensation signal to be injected into the second audio-listening channel based at least partially on the measured signal level;
• and
• inject at least a part of the first input signal into the second audio-listening channel based at least partially on the determined compensation signal, thereby reducing a current level in the second audio-listening channel.

A system for reducing crosstalk in an audio-listening channel, the system comprising:

• a memory;
• a processor;
• a module stored in the memory, executable by the processor, and configured to:
• detect a first audio-listening channel and a second audio-listening channel;
• transmit from a first signal source a first input signal to a first amplifier associated with a first audio-listening channel;
• measure a signal level over at least a portion of a common path shared by the first audio-listening channel and a second audio-listening channel, wherein the common path includes at least some resistance;
• determine a compensation signal to be injected into the second audio-listening channel based at least partially on the measured signal level;
• and
• divert at least a part of the first input signal to the second audio-listening channel based at least partially on the determined compensation signal, thereby causing an output signal level of a second amplifier associated with the second audio-listening channel to substantially match the signal level over the common path.
