Specific transformations

Transformations

delaying :: Duration -> Span Source

A transformation that moves a value forward in time.

undelaying :: Duration -> Span Source

A transformation that moves a value backward in time.

stretching :: Duration -> Span Source

A transformation that stretches (augments) a value by the given factor.

compressing :: Duration -> Span Source

A transformation that compresses (diminishes) a value by the given factor.

Transforming values

delay :: Transformable a => Duration -> a -> a Source

Moves a value forward in time.

undelay :: Transformable a => Duration -> a -> a Source

Moves a value backward in time. Equnitvalent to stretch . negate.

stretch :: Transformable a => Duration -> a -> a Source

Stretches (augments) a value by the given factor.

compress :: Transformable a => Duration -> a -> a Source

Compresses (diminishes) a score. Equnitvalent to stretch . recip.

(|*) :: Transformable a => a -> Duration -> a infixl 7 Source

 Infix version of stretch.

(*|) :: Transformable a => Duration -> a -> a infixr 7 Source

 Infix version of stretch.

(|/) :: Transformable a => a -> Duration -> a infixr 7 Source

 Infix version of compress.
