Electronic device and method for correcting sound signal thereof

Electronic device in accordance with various embodiments of the present invention, a sound input unit that senses the sound (sound) convert the first sound signal; Group is connected to the sound input unit and electrically, the first received sound signal, and a processor for generating a second sound signal by performing a predetermined signal processing, signal processing for the processor to perform, the first sound signal the predetermined cut-off (cut-off) operation of detecting a frequency band having a certain level or more in a first frequency band exceeding the frequency; Operable to generate a harmonic (harmonic) signal including a plurality of frequency bin having the same level as the signal of the detected frequency band (frequency bin); And it may include an operation of the first superimposed on the sound signal to the harmonic signal. Other are possible in various embodiments.
