-- Basic Audio Operations --
----------------------------

getAudio : String -> Task Http.Error Audio

play : Audio -> Task error ()

stop : Audio -> Task error ()

pause : Audio -> Task error ()

seek : Time -> Audio error ()

startAt : Time -> Audio -> Task error ()

loop : Audio -> Task error ()

getSupportedFormats : Task error (List String)

setVolume : Float -> Audio -> Task error ()

mute : Audio -> Task error ()
mute = setVolume 0

setSpeed : Float -> Audio -> Task error ()

-- Filters --
-------------

-- Either have filters be of this type

type alias Filter = Audio -> Audio

-- or have a way to apply filters to an Audio

filter : Filter -> Audio -> Audio


-- This way is simply imperative
connect : Audio -> AudioOutput -> Task error ()
disconnect : Audio -> Task error ()
-- Alternatively, you can module the Audio as a tree of nodes eventually 
-- connecting to one or more outputs. This would make the 
-- connect an disconnect functions functional and hence not involve tasks


-- The gain filter options should follow the Web Audio API
gainFilter : GainFilterOptions -> Filter

-- The bi-quad filter options should follow the Web Audio API
biquadFilter : BiquadFilterOptions -> Filter 

-- The oscillator options should follow the Web Audio API
oscilator : OscillatorOptions -> Audio
-- You can the define square, triangular, or whatever types of waves
-- from this function.
