How does increasing sample rate impact sound quality and file size?

Increasing the sample rate in audio recording directly impacts sound quality and file size in a significant way. When the sample rate is increased, more samples of the sound wave are taken per second, which leads to a more accurate representation of the audio being captured. This results in improved sound quality, as higher frequencies can be captured more effectively and the overall fidelity of the sound increases.

However, higher sample rates also lead to larger file sizes. This is because more data is being processed and stored for the same duration of audio — the more samples taken, the more information needs to be saved. Hence, the correct answer indicates that, while the sound quality improves, the file size also increases as a result of these higher sample rates. This relationship between sample rate, sound quality, and file size is crucial for anyone working in audio production or any field that involves sound processing.
