Personalized sound virtualization

A personalized sound virtualization system, comprising:

• a first microphone of a wearable audio device, wherein the first microphone is configured to measure environmental sound, and wherein the first microphone is configured to be in or proximate to a right ear of a user;
• a second microphone of the wearable audio device, wherein the second microphone is configured to measure the environmental sound, and wherein the second microphone is configured to be in or proximate to a left ear of the user;
• an inertial measurement unit (IMU) of the wearable audio device, wherein the IMU is configured to capture motion data while the first microphone and the second microphone measure the environmental sound;
• and
• a processor configured to:
• calibrate, based on the motion data, acoustic data obtained from the measuring of the environmental sound via the first and second microphones to generate motion-adjusted acoustic data;
• using the motion-adjusted acoustic data obtained from measuring the environmental sound via the first and second microphones, calculate one or more individualized parameters relating to at least one individualized head related transfer function (HRTF) for the user, wherein the one or more individualized parameters comprise a head width of the user, and wherein the head width is determined at least partly based on an interaural time delay;
• and
• use the one or more individualized parameters to adjust audio playback by the wearable audio device.
