Abstract

The invention relates to an audio information processing method and a conference terminal thereof. The audio information processing method comprises the steps of: picking up a sound; determining a microphone closest to a sound source according to the sound, determining a sound source distance according to audio information obtained by the microphone and a prestored corresponding relation between a sound pressure level difference value and a distance ratio, and outputting the audio information and distance information; and performing power amplification processing on the audio information according to the distance information. Since the distance of the sound source is judged according to the difference between sound pressure values picked up by different microphones, and the audio information is subjected to amplification processing by means of a power amplification module according to the sound source distance, the conference terminal can automatically adjust volume whether the sound source is far away from or close to the conference terminal, and the volume of the output sound is relatively stable.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of audio technology, in particular to an audio processing method and a device thereof. [0003] 【Background technique】 [0004] In the field of conference audio and call products, traditional conference call machines need to be connected to a telephone line for calls and an AC adapter for power supply; such products are bulky, cumbersome to connect, difficult to carry, and must be placed where there are telephone lines to make calls. [0005] With the rapid development of bluetooth speakers, people found that there is a built-in microphone in the bluetooth speaker that supports the bluetooth call function of mobile phones. After cooperating with mobile phones, voice calls can also be realized. These products are easy to carry and support cell phone calls without a phone line. However, when in use, the distance between the sound source and the Bluetooth speaker needs to be kept short. When the distance between...
