Description

Light-weight sample parameter inference which will fit most needs. We only do "poor man's inference", only for sample rates. The sample rate will be provided as an argument of a special type T. This argument will almost never be passed explicitly but should be handled by operators analogous to '(\$)' and '(.)'.

In contrast to the run-time inference approach, we have the static guarantee that the sample rate is fixed before passing a signal to the outside world. However we still need to make it safe that signals that are rendered for one sample rate are not processed with another sample rate. We should wrap T s u t -> a in a Reader monad, but that's not all. We must investigate a little more here. Maybe we need another type parameter for the sample rate and the signals in order to show that they belong together, like it is done in the ST monad.

Documentation
 newtype T s u t Source
This wraps a function which computes a sample rate dependent result. Sample rate tells how many values per unit are stored for representation of a signal.

Instances
 Eq t => Eq (T s u t) Ord t => Ord (T s u t) (Show t, C u) => Show (T s u t)
 fromNumber :: C u => Recip u -> t -> T s u t Source
 toNumber :: C u => Recip u -> T s u t -> t Source
This function is somehow dangerous because it drops the s parameter.
 fromDimensionNumber :: C u => T (Recip u) t -> T s u t Source
 toDimensionNumber :: C u => T s u t -> T (Recip u) t Source
This function is somehow dangerous because it drops the s parameter.
 common :: Eq t => String -> T s u t -> T s u t -> T s u t Source
