- 1What is Digital Sound?Digital Sound is sound as a set of binary numbers.
- 2How do you turn analogue sound into binary?The analogue wave is measured and sampled at set intervals.
Each sample is then converted and stored as binary. - 3Sample Rate/FrequencyThe number of times the sound is sampled per second, measured in Hz.
Eg. 100Hz is 100 samples per second. - 4Bit RateThe Bit Rate is the space available for each sample, measured in kilobits per second (kbit).
Eg. 128kbits is 128 kilobits per second of sampled sound. - 5Low Sample RateVery few samples taken
Poor match between original and sample
Small file size required - 6High Sample RateMany more samples taken
Good match between original and sample
Large file size required
