Abstract
A method for recovering audio signals, a terminal and a storage medium are provided. The method includes: buffering an audio signal sampled at a preset number of sampling points each time, and then performing frequency spectrum analysis on the sampled audio signal by FFT; when it is determined that the audio signal is compressed, filtering a frequency point; recovering high-frequency signals based on audio signals before the frequency point; and performing phase recovery on the high-frequency signals. Thus, compressed high-frequency signals in the audio signals may be recovered.
