Integrated processing of multimedia signals can eliminate unnecessary
signal processors and converters without losing the functionality of
typical home entertainment system components. The integrated multimedia
system includes a main player that captures and processes signals
digitally. The main player may adjust the audio signal to provide audio
output of equal loudness across all frequencies by accounting for
sensitivity of the human ear for sounds of varying frequencies. The main
player can also account for perceived differences in loudness based on
the angle of a listener to a speaker by detecting the position of a user
and making an adjustment accordingly. The invention further provides a
speaker that has embedded performance characteristics or an identifier
that allows the system to provide an optimal speaker driving current for
a particular system or determine how that speaker would be best
implemented in the integrated system.
