#ratios(reduced: true) ⇒ Array<Tonal::Ratio, Tonal::ReducedRatio>

Returns the ratios of the subharmonic extended ratio.

Examples:

ser = Tonal::SubharmonicExtendedRatio.new(partials: [6,5,4])
ser.ratios => [1/1, 6/5, 3/2]

Parameters:

  • reduced (Boolean) (defaults to: true) —

  end
end

#to_extended_ratio ⇒ Tonal::ExtendedRatio Also known as: to_efr

Returns the harmonic extended ratio.

Examples:

ser = Tonal::SubharmonicExtendedRatio.new(partials: [6,5,4])
