4p: Explain how attributes such as sampling frequency and sample size affect characteristics such as representation size and perceived quality, and the trade-offs involved
Keyword | Definition |
---|---|
perceived quality | the more closely the digital representation of a sound matches the original analogue sound wave, the better quality the sound will appear to people listening |
representation size | the number of bytes needed to store or transfer an audio recording |
sample size | the number of bits used to represent each sample of a sound wave. A higher value means the digital representation is closer to the original analogue sound but the recording will take up more bytes of storage. |
sampling frequency | the number of samples of a sound wave taken every second. A higher value means the digital representation is closer to the original analogue sound but the recording will take up more bytes of storage. |
trade-off | a balancing act where improving one thing will have a negative effect elsewhere |
