Again, you’re not understanding how Nyquist works.
See the part about “sample rates” in the middle of the page.
Forgive me if I rely on my audio recording degree, 15 years as a recording engineer, and 30 years as an audio hobbyist over your ability to google something.
Nyquist stated that to reproduce a certain frequency, you need a sample rate of at least twice that frequency. This doesn’t mean that a higher sampling rate only gives you more high frequencies/more frequency response. It does allow for a wider frequency response, but the point of it is to capture more plot points to reconstruct the signal (as per the chart in the link above).
If you want to tell me more about what I don’t know, feel free to PM me here, but we can stop cluttering up this post with the technical discussion.
