Embodiment 1

[0064] Embodiment one: refer to Figure 6 As shown, when the first sound card is a physical sound card 601, and the second sound card is a physical sound card 602, the sound mixing system in the embodiment of the present invention includes a physical sound card 601, a physical sound card 602, a first sound mixing device 603, and a second sound mixing device. Sound device 604, audio playback device 605, network data processing device 606, loudspeaker 609 and microphone 610, wherein:

[0065] The audio playback device 605 is connected to the physical sound card 601 and the second sound mixing device 604 respectively, and is used to output the first audio data to the physical sound card 601 and the second sound mixing device 604 respectively;

[0066] The physical sound card 601 is respectively connected with the audio playback device 605, the first sound mixing device 603 and the second sound mixing device 604, and is used to obtain the above-mentioned first audio data through t...

Embodiment 2

[0078] Embodiment 2: The first sound card of the above-mentioned sound mixing system may also use a virtual sound card. A virtual sound card is a virtual sound card driver. Because the function of a virtual sound card is the same as that of a physical sound card, it is used to realize functions such as sound recording and mixing. Therefore, when the first sound card is a virtual sound card, the use process and data flow of the audio mixing system are similar to those in Embodiment 1, so details will not be repeated here.

[0079] Using a mixing system that uses a virtual sound card as the first sound card, the customer using the remote device can hear the multimedia ringtone and the voice of the agent, but will not hear the voice sent by the customer himself sent by the remote device, thereby avoiding the echo phenomenon Occurs, the quality of audio transmission is improved, and, because only one physical sound card is used, the function of the first sound card is realized thr...

Abstract

The invention discloses a sound mixing system and method. The sound mixing system comprises a first sound card, a first sound mixing device, a second sound card and a second sound mixing device, wherein the first sound card is used for receiving first audio data; the first sound mixing device is used for receiving the first audio data transmitted by the first sound card, receiving the mixing sound of second audio data sent by remote equipment to obtain first synthetic audio data, and displaying the first synthetic audio data through a loudspeaker; the second sound card is used for obtaining third audio data and transmitting the third audio data to the second sound mixing device; and the second sound mixing device is used for receiving the first audio data transmitted by the first sound card and the third audio data transmitted by the second sound card, carrying out sound mixing on the first audio data and the third audio data to obtain second synthetic audio data, and sending the second synthetic audio data to the remote equipment to solve a problem that the audio playing effect of the remote equipment is poor, caused by echo.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a sound mixing system and method. Background technique [0002] With the development of Internet technologies, communication services based on Internet Protocol (Internet Protocol, IP) in telecommunication services are more and more widely used, for example, text chat services, voice call services, and the like. In IP-based communication services, call center (Call Center) is a relatively common application, and many units have their own call centers. In the traditional call center, there is only call service. With the popularity of computers, the new call center also has multiple functions such as information inquiry, sending and receiving e-mail, short message and fax. In the call center, operators (seats) mainly perform operations such as manual connection, and the seats generally use the seat terminal to complete services such as information inquiry, sending and rece...
