Sound Flashcards
How do u calculate the representation of the size of sound?
Sample size x Sample rate x Duration
How can u convert a sound wave into numeric values?
Take readings at specific time intervals and record them
How does an analogue to digital converter work
It will capture a sound wave at regular time intervals
How does a computer interpret analogue sound waves?
By digitizing it (turning it into binary values)
How do we digitize sound?
By taking samples
What is sampling
Taking a measurement at regular time intervals
What is sample rate
Number of measurements taken per second. Sample rate is number of sample recorded in any given period of time
How can we improve the result of representing sound
By increasing the number of samples per second
What is sample resolution or size
The number of bits used to represent each sample
How do we increase sample resolution
By using more more bits to represent each sample
What is bit rate
A measure of how much data is processed for each second of sound
What is sound made of
Analogue waves
What is compression
Reducing number of bits in a file
What is Lossy compression
When some detail in the original file is lost, It removes data that is least likely to be noticed.AN image can be compressed by reducing its color depth
What is lossless compression
When the original file can be restored without loss, is doesnt remove data so that the orgignal can be restored. Lossless compression does not achieve same file reduction as lossy
