Problems solved by technology

[0003] However, it is inconvenient for the user to manually adjust the volume, and, in some usage situations, because the sound frequency of the ambient sound is higher than the sound frequency of the output audio itself, and the sound with high frequency is sharper than the sound with low frequency. , and the human ear is more sensitive to sharp sounds than to low sounds, so even if the volume of the output audio is adjusted higher than the ambient pitch, you may only hear the ambient noise, but cannot hear the content of the output audio clearly

Embodiment Construction

[0018] see figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the output audio adjustment method of the present invention.

[0019] The output audio adjustment method includes the following steps:

[0020] S101, acquiring the frequency of the current ambient sound and the frequency of the current output audio;

[0021] S102, judging whether the frequency difference between the output audio and the environmental sound is smaller than a preset threshold;

[0022] S103. If it is less than the preset threshold, increase the frequency of the output audio.

[0023] Wherein, for step S101, the frequency and volume of the ambient sound may be measured in real time by a sound sensor. The frequency and volume of the output audio can be measured in real time by a sound sensor, or can be obtained by reading the relevant parameters of the output audio in the audio and video data.

[0024] In particular, since the environmental sound may include noises of variou...

Abstract

The invention provides an adjusting method of an output audio and a system of the output audio. The adjusting method of the output audio comprises the following steps: obtaining the frequency of the current environmental sound and the frequency of the current output audio; judging whether the difference value of the frequency of the output audio and the frequency of the environmental sound is smaller than a preset threshold; and improving the frequency of the output audio when the difference value of the frequency of the output audio and the frequency of the environmental sound is smaller than the preset threshold. The adjusting method of the output audio and the system of the output audio have the advantages of being capable of automatically adjusting the output audio frequency according to environmental noise, enabling a user to clearly hearing the content of the output audio frequency as much as possible in various using environments, and being free of manually adjusting audio output in the process of audio / video playing.

Description

technical field [0001] The invention relates to the technical field of audio adjustment, in particular to an output audio adjustment method and an output audio adjustment system. Background technique [0002] In the process of audio and video playback, it is often encountered that there is a lot of noise in the surrounding environment. When the environmental noise is large, it is often necessary to manually increase the volume of the audio output so that the audio can still be heard under high environmental noise. Hear the audio content being played clearly. [0003] However, it is inconvenient for the user to manually adjust the volume, and, in some usage situations, because the sound frequency of the ambient sound is higher than the sound frequency of the output audio itself, and the sound with high frequency is sharper than the sound with low frequency. , and the human ear is more sensitive to sharp sounds than to low sounds, so even if the volume of the output audio is ...
