Embodiment Construction

[0022] refer to figure 1 , the sound effect processing method in an embodiment, includes the following steps.

[0023] S110: Collect environmental sound signals within a preset time range.

[0024] The preset time range refers to a time range preset for a time period or a preset duration. Specifically, the sound signal can be obtained by collecting the sound of the surrounding environment through a microphone.

[0025] In one embodiment, the preset time range is a time range starting from the time when the playback instruction is received and having a preset value as a duration. Wherein, the play instruction refers to an instruction for instructing to start audio / video playback or TV program playback, for example, an instruction to wake up the processing system when the TV is turned on. The preset value can be specifically set according to actual needs. In this embodiment, the default value is 5 seconds; when the time of receiving the play instruction corresponds to the ti...

Abstract

The invention relates to a sound effect processing method and system. The method comprises the following steps: collecting environmental sound signals within a preset time range; performing feature extraction on the environmental sound signals to obtain an environmental sound feature; selecting a reference sound feature having the largest similarity with the environmental sound feature from a plurality of preset reference sound features; searching a preset sound effect mode corresponding to the selected reference sound feature to obtain a matching sound effect mode; and performing sound effect processing on a to-be-played sound signal according to the matching sound effect mode. Therefore, the most suitable matching sound effect mode can be automatically selected according to the environmental sound feature of the environmental sound signals, so the sound effect processing effect is good; and meanwhile, no user operation is required, so use convenience of users is improved.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a sound effect processing method and system. Background technique [0002] When the audio and video playback device plays audio, video or programs, different sound effect modes can be set as required. Taking a TV as an example, the traditional method for changing the sound effect mode is that the user uses a remote controller to select on the displayed menu interface, and the processing system of the TV performs processing on the sound signal according to the sound effect mode selected by the user and then outputs it. [0003] However, there is usually noise in the external environment where the TV is located, and the user does not know which sound effect mode is the most suitable for the current environment. The processing effect is poor. Contents of the invention [0004] Based on this, it is necessary to provide a sound effect processing method and system with go...
