Sound.SC3.Lang.Data.Vowel

Data set giving formant locations for Vowels.

Lookup functions

formant :: Num n => Fn -> Fdata n -> (n, n, n)

Extract Fnth formant triple of an Fdata.

 formant F1 (fdata Bass I) == (1750,-30,90)

fdata :: Num n => Voice -> Vowel -> Fdata n

Lookup formant Fdata given Voice and Vowel.

 fdata Bass I == (Bass,I,[250,1750,2600,3050,3340]
                        ,[0,-30,-16,-22,-28]
                        ,[60,90,100,120,120])

formants :: Num n => Fdata n -> [(n, n, n)]

Formant triples of an Fdata.

 formants (fdata Bass I) == [(250,0,60)
                            ,(1750,-30,90)
                            ,(2600,-16,100)
