1. Field of the Disclosure
The present disclosure relates generally to a method for outputting audio signals and an electronic device for supporting the same. In particular, the present disclosure relates to a method and an electronic device for adjusting an audio signal by a filter and outputting the adjusted audio signal.
2. Description of the Related Art
Audio data is reproduced by means of a multimedia player to then be output through a speaker. A faithful output of the original sound depends on the performance of the speaker and the characteristics of an audio processing unit of the player. Various techniques have been developed in order to faithfully reproduce the original sound.
With recent developments in technology, the audio processing unit may obtain the original sound by using a loudness equalization process that strengthens a low level signal to compensate for the non-linear characteristics of human ears. Another audio processing unit may generate harmonic waves by forming an absolute value by means of the rectifier arrangement. The audio processing unit may process the audio data based on the generated harmonic waves.
If audio data is input into two channels, the audio data may be output to speakers that correspond to the two input channels, respectively. Accordingly, there may be limitations on the increase in the low-band performance of the audio data.
