The invention discloses a method and a device for performing sound effect control on played audio frequency. The method comprises the steps of receiving a target frequency response curve currently input by a user and determining a waveform function of a filter at an audio frequency playing terminal according to the waveform features of the received target frequency response curve currently input by the user; adjusting work parameters of the filter to enable the waveform curve output by the filter according to the determined waveform function to be consistent with the received target frequency response curve currently input by the user; controlling the filter to output the waveform to the audio frequency playing terminal for playing the audio frequency according to the adjusted work parameters of the filter. The method and the device for performing sound effect control on the played audio frequency realize that the frequency response value of the audio frequency playing terminal is correspondingly adjusted according to the command of the user, so the sound quality of the audio frequency played by the audio frequency playing terminal is adjusted to correspond to the command of the user.
Description
technical field [0001] The present invention relates to the field of audio playback, in particular to a method and device for controlling sound effects of played audio. Background technique [0002] Currently, audio playback terminals (for example, stereos or televisions) on the market have only one or several sound effect modes, and the system frequency responses corresponding to various sound effect modes are fixed. When the audio playback terminal plays audio, the user can only select one of the pre-stored audio modes for the audio playback terminal to play audio. [0003] However, in fact, different users have different requirements for the sound quality of the audio played; some people like to listen to bass, and some people like to listen to treble or midrange. Existing audio player terminals with pre-stored fixed audio playback sound effect modes cannot dynamically adjust the frequency response value of the audio player terminal according to the user's demand for the...
