Abstract: Techniques for determining personalized head-related transfer functions (HRTFs) using a head-mounted device and in-ear devices include: receiving, from a sensor array of the head-mounted device, a first sound signal associated with a sound from a sound source in a local environment of a user of the head-mounted device; determining that reverberation characteristics and spectral characteristics of the sound meet predetermined criteria based on the first sound signal; determining that the sound source is stationary within a time period; determining a relative location of the sound source with respect to the user; receiving, from an in-ear device in an ear of the user, a second sound signal associated with the sound from the sound source; and determining, based on at least the second sound signal, an HRTF or one or more parameters of the HRTF associated with the relative location of the sound source for the user.
