Constructor & Destructor Documentation

Reciprocal()

template<typename Sample = double>

signalsmith::curves::Reciprocal< Sample >::Reciprocal ( Sample  y0, Sample  y1, Sample  y2  )

inline

If no x-range given, default to the unit range.

Method Details

barkRange()

template<typename Sample = double>

static Reciprocal<Sample> signalsmith::curves::Reciprocal< Sample >::barkRange ( Sample  lowHz, Sample  highHz  )

inlinestatic

Returns a map from 0-1 to the given (non-negative) Hz range.

barkScale()

template<typename Sample = double>

static Reciprocal<Sample> signalsmith::curves::Reciprocal< Sample >::barkScale ( )

inlinestatic

Decent approximation to the Bark scale.

The Bark index goes from 1-24, but this map is valid from approximately 0.25 - 27.5. You can get the bandwidth by barkScale.dx(barkIndex).

then()

template<typename Sample = double>

Reciprocal signalsmith::curves::Reciprocal< Sample >::then ( const Reciprocal< Sample > &  other ) const

inline

Combine two Reciprocals together in sequence.
