Sampling Rate & Sample Resolution Flashcards

All 5 cards in this deck

What is the sampling rate of a sound recording?: The number of samples taken per second, measured in hertz (Hz).
What is sample resolution?: The number of bits per sample.
What is the effect of increasing the sampling rate of a sound recording?: The recording is closer to the original sound so playback quality improves, but the file size increases.
What is the effect of increasing the sample resolution of a sound recording?: Each sample can be stored more precisely, so playback quality improves, but the file size increases.
What is 1 hertz (Hz) when sampling sound?: One sample per second.
