Abstract: Disclosed is an electronic apparatus. The electronic apparatus outputs a first sound having a first characteristic for measuring a listening environment through an output unit, acquires first listening environment information based on a first feedback sound received through a receiving unit based on the output first sound, outputs a second sound having a second characteristic through the output unit based on receiving input through the receiving unit, acquires second listening environment information based on a second feedback sound received through the receiving unit based on the output second sound, and performs audio correction based on the acquired first listening environment information and second listening environment information.

Abstract: An electronic apparatus is provided. The electronic apparatus includes a microphone and a processor configured to, based on a second sound including a first sound of an audio signal being received through the microphone, obtain a noise about the electronic apparatus based on the audio signal and the second sound, obtain an enduring component of the noise, and based on the enduring component being equal to or greater than a threshold value, process the audio signal.

Abstract: An apparatus for outputting an audio signal includes: a channel processor configured to generate two or more channel signals from audio data; a signal processor configured to render the generated two or more channel signals; and a directional speaker configured to reproduced a rendered channel signal as an audible sound. The signal processor may include a frequency converter configured to generate a channel signal of a frequency domain by converting the generated two or more channel signals through frequency conversion, and a re-panner configured to change a channel gain of at least one of the generated channel signals by as much as an adjustment value for the channel gain, wherein the adjustment value is monotonically changed as a frequency of the channel signal of the frequency domain increases.
