Type aliases such as Swift

A type alias is a selectable name defined for an existing type. You can define a type alias by keyword Typealias.

Aliases are useful when you want to refer to an existing type by a name that looks more appropriate in the context, such as when using data from an externally indicated size:

Typealias audiosample = UInt8

Once you have defined a type alias, you can use the type alias anywhere in place of the original type name:

var maxamplitudefound = audiosample.min//maxamplitudefound = 0

Here, Audiosample is defined as a UINT type alias, and calling Audiosample.min is actually calling Uint8.min, returning a number with a value of 0 to initialize the Maxamplitudefound variable.
