声卡的输入输出接口稳定性也是影响音质的重要因素。如果接口不稳定或存在干扰，可能会导致音频信号的丢失或变形，从而影响音质。高质量的声卡通常具有更好的接口设计和屏蔽措施，以减少外界干扰对音质的影响。 三、英文翻译 In-depth Analysis: The Impact of Sound Card on Sound Quality In audio equipment, the sound card plays a crucial role. It is not only a bridge connecting the computer and audio equipment, but also one of the key factors affecting sound quality. This article will delve into the impact of sound cards on sound quality. I. Basic Structure and Function of Sound Card A sound card, also known as an audio card or audio controller, is one of the most basic components of a computer's multimedia system. It mainly includes a digital signal processor (DSP), audio codec, input and output interfaces, and other parts. The main functions of the sound card include processing digital signals, providing high-quality audio input and output, and ensuring the authenticity and naturalness of sound quality.

1. Digital Signal Processing Capability The digital signal processing capability of the sound card directly affects the clarity and delicacy of the sound quality. A good sound card can accurately and efficiently process audio signals, avoiding sound quality loss caused by signal loss or improper processing. Conversely, a low-quality sound card may fail to correctly process complex audio signals, resulting in distortion or noise in the sound quality. 2. Quality of Codec The codec is the key part of the sound card responsible for audio coding and decoding. High-quality codecs can ensure stable audio quality during transmission and playback, reducing sound quality loss caused by coding and decoding. Low-quality codecs may cause sound quality degradation or noise. 3. Stability of Input and Output Interfaces The stability of the input and output interfaces of the sound card is also an important factor affecting sound quality. If the interface is unstable or there is interference, it may lead to the loss or distortion of audio signals, thereby affecting the sound quality. High-quality sound cards usually have better interface design and shielding measures to reduce the impact of external interference on sound quality.
