1. 选择高质量的声卡 购买声卡时，应选择知名品牌、高评价的产品。关注其采样率、信噪比等关键参数，以确保其具有较好的音频处理能力。 2. 更新驱动程序和软件 定期更新声卡的驱动程序和软件，以确保其与操作系统和网络设备的兼容性。这有助于提高声卡的性能和稳定性。 3. 调整声音设置 在通话过程中，根据网络状况和设备性能，适当调整声音设置，如降低音量、调整麦克风灵敏度等，以获得更好的通话效果。 四、英文翻译 How Does a Computer Sound Card Affect Online Voice Calls? Introduction: In today's digital era, online voice calls have become one of the important ways for people to communicate with others in their daily lives. As a key component for audio signal processing and transmission, the performance and quality of a computer sound card have a significant impact on the quality of online voice calls. This article will explore how a computer sound card affects online voice calls and analyze the underlying principles and factors. Impact of Sound Card on Online Voice Calls: 1. Audio Quality: The main function of a sound card is to process audio signals, including input and output. In online voice calls, the sound card is responsible for converting sound signals into digital signals, which are then transmitted over the network to the other end. Therefore, the audio processing capability of the sound card directly affects the sound quality of the call. A high-quality sound card can provide clearer and more realistic sound, making the call more natural. Conversely, a low-quality sound card may cause sound distortion and noise, affecting the call experience. 2. Transmission Speed: Apart from audio quality, a sound card also affects the transmission speed of online voice calls. In network communication, sound signals need to be compressed and encoded before they can be transmitted over the network. The performance of the sound card will directly affect the efficiency of this process, thereby affecting the real-time nature of the call. High-quality sound cards usually have higher sampling rates and larger buffers, which can better process sound signals and reduce transmission delays. 3. Compatibility: The compatibility of a sound card is also an important factor that affects online voice calls. If the sound card is not compatible with the computer system or network equipment, it may cause problems with the call. Therefore, when selecting a sound card, it is necessary to ensure its compatibility with the computer system, network equipment, and related software. How to Optimize Sound Card Performance to Improve Online Voice Call Quality: 1. Choose a high-quality sound card: When purchasing a sound card, choose a well-known brand and high-rated products. Pay attention to key parameters such as sampling rate and signal-to-noise ratio to ensure good audio processing capabilities. 2. Update drivers and software: Regularly update the drivers and software for your sound card to ensure compatibility with your operating system and network equipment. This can improve the performance and stability of your sound card.

3. Adjust sound settings: During the call, adjust the sound settings accordingly based on network conditions and device performance, such as reducing volume, adjusting microphone sensitivity, etc., to achieve better call results.
