Processing a multi-channel signal for output to a mono speaker

A system comprising:

• a digital audio source configured to provide digital audio having at least two audio channels;
• and
• an electronic device configured to receive the digital audio from the digital audio source, to change a relative timing between a first of the at least two audio channels and a second of the at least two audio channels based at least in part on a phase relationship between the first and the second of the at least two audio channels such that a power of a summation of the first and the second of the at least two audio signals substantially exceeds a power of a difference between the first and the second of the at least two audio signals, and to output a monaural audio signal based at least in part on the first and the second of the at least two audio channels.

A method comprising:

• receiving, into a processor, a first digital audio channel signal and a second digital audio channel signal;
• and
• outputting a monaural digital audio signal that includes components of the first digital audio channel signal and the second digital audio channel signal, wherein the monaural digital audio signal is based at least in part on a phase relationship between a portion of the first digital audio channel signal of a frequency band and a portion of the second digital audio channel of the frequency band, wherein the monaural digital audio signal is a summation of the components of the first and second digital audio channel signals only when a power of the summation of the first digital audio channel signal and the second digital audio channel signal exceeds a power of a difference between the first digital audio channel signal and the second digital audio channel signal.
