What is sampling rate measured in?
Short answer. Hertz, samples per second.
What happens when you raise the sampling rate?
Better sound, bigger file.
Sampling sound
| Term | Means |
|---|---|
| Sample | one measure |
| Sampling rate | per second |
| Resolution | bits each |
Remember
| Higher rate: better sound |
| Bigger file too |
Sound is a wave. How does a computer store it? By sampling. A sample measures the wave once. Sampling rate is samples per second. Sample resolution is bits per sample. Remember. Higher values sound better. The file gets bigger.
