What is the sound card used for in live broadcast?

As you must know, in live performances or large conferences, if you want to hear clearly, you should use the sound system, such as picking up the sound with a microphone and pushing the sound with high power. Then, if we want the audience in the tens of millions of live broadcast rooms to hear our wonderful performances clearly, we also need a sound system, so the sound card has become an indispensable device. The sound card can be connected with various audio devices and microphones, and is responsible for sending the collected sound to the audience in the live broadcast room. Theoretically, it is more advanced and complicated than live audio equipment. The live audio equipment only needs to hear it by itself, while the live webcast not only needs to hear it by itself, but also needs to be heard by live viewers thousands of miles away.

So is it okay not to use a sound card? Of course, it is also possible, because both computers and mobile phones have their own sound cards. Since we have a sound card, why do we need it? Because most computer sound cards are just a basic sound card output, not some modification of the sound. Because what we need in the live broadcast is not a simple sound, but a good sound for everyone, so we need a sound card. So the sound card is mainly to better modify the sound.
