Data Storage (sound) Flashcards
What is sample frequency?
The number of audio samples captured every second
What is sample size?
Number of bits available per sample
What is sample rate?
The number of bits used per second of audio
How can sound be sampled and stored in digital form?
Sound exists as waves however, computers do not understand waves therefore you would need to convert these waves into binary. Digital sound is broken into thousands of samples per second - each of these samples is then stored as binary data. The higher the bit depth the better the sound quality. Bit rates are usually measured in kilobits per second (kbps).
What is the formula for bit rate for audio?
Frequency x bit depth x channels = bit rate
What is the calculation for audio file?
bit rate x duration = file size
What is bit depth?
Number of bits available for each sample
