A higher sampling rate when capturing sound generally:
A. Captures more samples per second, improving high-frequency detail and enlarging an uncompressed file✓ 答案
B. Removes background noise perfectly
C. Converts the recording into text
D. Reduces file size with no other effect
解說
Sampling rate sets how many measurements per second are taken. Higher rates capture higher frequencies more accurately but store more samples, so an uncompressed file grows. Resolution is the other quality factor.
