Sound File Sizes Flashcards

All 2 cards in this deck

What is the formula for the file size of a sound file, in bits?: sampling rate (Hz) $\times$ sample resolution (bits) $\times$ duration (seconds)
True or false? Doubling the sample resolution of a sound recording doubles its file size.: True. File size = sampling rate $\times$ sample resolution $\times$ duration.
