What setting gives the clearest digital audio when using a capture card?

Explanation:
In digital audio, clarity comes from two things: how accurately the sound is sampled and how much detail is kept per sample. The sampling rate determines the highest frequency you can faithfully capture (Nyquist). For video work, 48 kHz is the standard because it aligns with common video frame rates and broadcast workflows, helping keep audio and video in sync across devices and software. The bit depth sets how much dynamic range you can capture; 16-bit is sufficient for most spoken dialogue and ambient sound in video, giving plenty of headroom without inflating file size. Higher sampling rates like 96 kHz offer more theoretical detail, but they require more bandwidth and processing, and they don’t necessarily translate into noticeable improvement for typical video content. A 44.1 kHz rate is CD-quality and widely used for pure audio music, but 48 kHz is preferred for video to maintain compatibility and synchronization. A low rate like 22.05 kHz would miss high frequencies and sound poor. So, 48 kHz at 16-bit provides reliable, clean audio that works well with the rest of the video pipeline.
