Sound
Sampling
Takes measurements of amplitude of the sound wave at various points
Each sample there will be a measurement
Converting analogue sound signal into a set of binary numbers then are stored in a digital file.
Sample
Each value is converted into the equivalent binary number.
Stored digitally
Tens of thousands of samples making up complete track
More samples, larger the file
Frequency
Rate samples are taken (Kilohertz - thousands of times per second)
Minimum sample rate is at least twice the highest frequency in the signal.
Sampling bit depth
Number if bits used per sample
Channel
Single sound stream
Mono sound has information about only a single channel
Stereo/surround sound will have multiple channels to make use of multiple speakers
Has its own samples
