1. A method for perceptual rendering of audio for playback by a headphone, the method comprising:
optimizing a first finite impulse response (FIR) filter associated with a first channel of audio input of audio associated with a source, for application to a first transducer of a headphone for output; and
optimizing a second FIR filter associated with a second channel of audio input of the audio associated with the source, for application to a second transducer of the headphone for output, wherein optimizing the second FIR filter further comprises modifying the second FIR filter to include at least one coefficient defined based upon a relationship between the first transducer and a second transducer, wherein the modifying includes applying a derivative of the second FIR filter to the second FIR filter to modify a phase component of the second FIR filter.
