Abstract:
An audio reproduction device and method for audio control based on room-correction (RC) and head related transfer function (HRTF) are provided. The audio reproduction device includes a speaker that reproduces a first audio signal. The audio reproduction device receives a plurality of second audio signals indicative of frequency responses captured based on the first audio signal and captured by a plurality of audio capturing devices positioned on a head wearable device of a user present within an enclosed physical space. The audio reproduction device determines RC preset for one or more RC filters associated with the speaker, based on the captured frequency responses. The audio reproduction device further determines HRTF associated with the user based on the captured frequency responses, and user-specific information of the user. The audio reproduction device further controls audio reproduction of the speaker based on the determined RC preset and the determined HRTF.
