Using Binary to Represent Sound Flashcards
1
Q
How does it work?
A
A computer takes samples of the sound wave at regular intervals, converts the samples into binary and stores them. The computer can then re-create the sound by reversing the process.
2
Q
What effects the file size and quality?
A
Sample rate
Bit rate
3
Q
What is sample rate?
A
Number of samples taken each second. Measured in Hz.
High sample rate = higher quality but larger file size.
4
Q
What is bit rate?
A
Amount of bits used to store the different levels of sound at each sampling interval.
More bits = greater range of levels that can be distinguished. Increases file size.
