Abstract

The invention belongs to the technical field of signal processing, and particularly relates to a signal clipping detection method and device, a terminal and a computer readable storage medium, and the signal clipping detection method comprises the steps: obtaining a to-be-detected signal; determining an amplitude histogram of the to-be-detected signal, wherein the amplitude histogram comprises a plurality of amplitude intervals; if a first amplitude interval of the amplitude histogram jumps, determining an amplitude corresponding to the first amplitude interval as a clipping threshold of the to-be-detected signal; carrying out clipping detection on the to-be-detected signal by utilizing the clipping threshold value; and improving the precision of signal clipping detection.

Description

technical field [0001] The present application belongs to the technical field of signal processing, and in particular relates to a signal clipping detection method, device, terminal and computer-readable storage medium. Background technique [0002] Clipping is a form of distortion of a signal that can occur when a signal is digitized, or any other time an analog-to-digital conversion of a signal occurs. For example, soft clipping or hard clipping occurs. [0003] In order to facilitate the repair of a clipped signal, it is first necessary to perform clipping detection on the signal to determine whether the signal is clipped. However, the current clipping detection method can usually only detect the hard clipping of the signal when the signal is hard clipping, but cannot detect the soft clipping of the signal when the signal is soft clipping , there is a problem of low clipping detection accuracy.
