One embodiment provides a method of personalized headphone equalization system for a headphone. The method comprises obtaining a measurement of sound pressure level at a microphone mounted in a near field of a headphone driver of the headphone and inside a cavity formed by the headphone and a user's ear. The method further comprises providing personalized equalization (EQ) of output reproduced via a headphone driver by performing EQ correction of the output based on the measurement of sound pressure level and a pre-determined target frequency response for the headphone, resulting in an equalized output that is adapted to individual characteristics of the user's ear.

Personalized headphone equalization

One embodiment provides a method comprising determining an actual elevation of a sound source. The actual elevation is indicative of a first location at which the sound source is physically located relative to a first listening reference point. The method further comprises determining a desired elevation for a portion of an audio signal. The desired elevation is indicative of a second location at which the portion of the audio signal is perceived to be physically located relative to the first listening reference point. The desired elevation is different from the actual elevation. The method further comprises, based on the actual elevation, the desired elevation and the first listening reference point, modifying the audio signal, such that the portion of the audio signal is perceived to be physically located at the desired elevation during reproduction of the audio signal via the sound source.

Modifying an apparent elevation of a sound source utilizing second-order filter sections

One embodiment provides a sound apparatus comprising a plurality of driver units arranged linearly in an end-fire array, and for each driver unit, a corresponding digital filter for individual digital signal processing of signals received by the driver unit.
