A system with sound adjustment capability is provided. The system includes a head-mounted device, a first loudspeaker and a processor. The first loudspeaker is detachable from the head-mounted device. The processor is configured to detect a plurality of positions and a plurality of orientations of the head-mounted device and the first loudspeaker to determine whether the first loudspeaker is detached from the head-mounted device. The processor is further configured to modify a first audio signal by at least one first filter or at least one second filter to generate a filtered first audio signal. The at least one first filter is used when the first loudspeaker is coupled to the head-mounted device, and the at least one second filter is used when the first loudspeaker is detached from the head-mounted device. The filtered first audio signal is configured to drive the first loudspeaker.

System with sound adjustment capability, method of adjusting sound and non-transitory computer readable storage medium

A sound reproducing method used in sound reproducing apparatus that includes the steps outlined below is provided. An input sound signal related to listener data and sound source data is received. An encoding process is performed by multiplying the input sound signal by an encoding function matrix having entries related to a basis function to generate an encoding result. A decoding function matrix is retrieved from the storage and at least one direction parameter is applied to the decoding function matrix, wherein the decoding function matrix compensates a difference between an ideal approximation result and a modeled approximation result of the input sound signal. A decoding process is performed by multiplying the encoding result by the decoding function matrix having the direction parameter applied to generate an output sound signal. The output sound signal is reproduced.

A sound reproducing method used in sound reproducing apparatus that includes the steps outlined below is provided. A sound signal is generated with a 3D sound generating process according to listener data and sound data. Pre-recorded sound data is retrieved to further generate a target distance function corresponding to the sound distance. A fixed head-related transfer function corresponding to a fixed distance is retrieved. A target head-related transfer function corresponding to the sound distance is generated by adapting the target distance function to the fixed head-related transfer function. The sound signal is reproduced by multiplying the sound signal by the target head-related transfer function.

A method for obtaining Hi-Res audio transfer information is provided. The method is applicable to the electronic device having a processor. In the method, a first audio signal is captured and converted from the time domain into in the frequency domain to generate a first signal spectrum. Then, a regression analysis is performed on an energy distribution of the first signal spectrum to predict an extended energy distribution according to the first signal spectrum, and head-related parameters are used to compensate for the extended energy distribution to generate an extended signal spectrum. Finally, the first signal spectrum and the extended signal spectrum are combined into a second signal spectrum which is converted from the frequency domain into the time domain to generate a second audio signal including Hi-Res audio transfer information.
