Actual Sample Rate slightly off?

1. What happens when sample rate is too low?
2. What happens if sample rate is too high?
3. Is 48kHz a good sample rate?

What happens when sample rate is too low?

As the sampling frequency decreases, the signal separation also decreases. When the sampling frequency drops below the Nyquist rate, the frequencies will crossover and cause aliasing.

What happens if sample rate is too high?

Drawbacks of High Sample Rates

In theory, a higher sample rate will only capture frequencies at extremely high and low ends of the spectrum where listeners can't even hear them. This means you're spending more and using more space for music that doesn't have a noticeable improvement in sound.

Is 48kHz a good sample rate?

This sample rate is ideal because it won't use much disk space or more CPU power. Yet it will still deliver the authentic sound you need for your professional recordings. If you're working in the movie industry, then the best sample rate is 48 kHz, as it's the industry standard.
