Problems solved by technology

[0002] In the daily environment, there are often large signals that cause the MIC (MICPHONE) of the mobile phone to be close to saturation or saturated, and the collected voice signals cannot be processed normally, resulting in large distortion of the signal input to the processor and poor signal quality
[0003] In the prior art, the above problems are solved by reducing the front-end gain of the MIC, but in a large signal environment, the MIC itself is prone to saturation, which affects the normal signal processing capability, and reducing the front-end gain cannot solve the problem of output distortion of the MIC body

Embodiment Construction

[0026] In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described The embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

[0027] The sound signal processing method provided by the embodiment of the present invention is suitable for a call scene in a large signal environment. The large signal refers to a relatively large signal amplitude range, which easily exceeds the processing capability of components. The mobile terminal collects the user's voice signal throu...

Abstract

The embodiment of the invention discloses a sound signal processing method applied to the technical field of mobile terminals. The method comprises the following steps: detecting whether the amplitude of a sound signal obtained by a first sound collection device exceeds a preset numerical value, if so, switching a second sound collection device to an analog input channel, and obtaining sound signals through the second sound collection device, wherein the signal sensitivity of the second sound collection device is lower than that of the first sound collection device, processing the sound signals obtained by the second sound collection device, and outputting the processed sound signals. The embodiment of the invention further discloses a sound signal processing device, a mobile terminal and a computer readable storage medium, which can improve the collection quality of the sound signals.

Description

technical field [0001] The invention belongs to the technical field of mobile terminals, and in particular relates to a sound signal processing method and device, a mobile terminal and a readable storage medium. Background technique [0002] In the daily environment, there are often large signals that cause the MIC (MICPHONE) of the mobile phone to be close to saturation or saturated, and the collected voice signals cannot be processed normally, resulting in large distortion and poor signal quality of the input signal to the processor. [0003] In the prior art, the above problems are solved by reducing the front-end gain of the MIC, but in a large-signal environment, the MIC itself is prone to saturation, which affects the normal signal processing capability, and reducing the front-end gain cannot solve the problem of output distortion of the MIC itself. Contents of the invention [0004] The invention provides a sound signal processing method, device, mobile terminal and...
