We'll not only increase the sampling rate but also use more accurate testing equipment.

我会提高采样率， 还会使用更精确的检测设备。

Note that this sampling rate or sampling frequency of 44.1 kilohertz is the most common rate for recorded audio such as music and podcasts, and 48 kilohertz is the second most common sampling rate.

请注意，44.1 千赫的采样率或采样频率是音乐和录制音频最常见的采样率，而 48 千赫是第二常见的采样率。
