Method and device for processing audio signal |
摘要 |
An audio signal processing method includes following steps: playing a fundamental frequency signal by a media player; calculating a first fundamental frequency sound pressure value and a first harmonic sound pressure value of the fundamental frequency signal, and calculating a second fundamental frequency sound pressure value and a second harmonic sound pressure value of the audio signal; calculating a threshold sound pressure value according to the first fundamental frequency sound pressure value, the first harmonic sound pressure value, and the second fundamental frequency sound pressure value; and comparing the second harmonic sound pressure value and the threshold sound pressure value to generate a comparing result, and adjusting the second harmonic sound pressure value according to the comparing result. An audio signal processing device is also disclosed. |
