## Detailed Description

A collection of structs to pass as the template argument when setting the interpolation type for the DelayLine class.

## Class Documentation

## juce::dsp::DelayLineInterpolationTypes::None

struct juce::dsp::DelayLineInterpolationTypes::None

No interpolation between successive samples in the delay line will be performed. This is useful when the delay is a constant integer or to create lo-fi audio effects.

## juce::dsp::DelayLineInterpolationTypes::Linear

struct juce::dsp::DelayLineInterpolationTypes::Linear

Successive samples in the delay line will be linearly interpolated. This type of interpolation has a low computational cost where the delay can be modulated in real time, but it also introduces a low-pass filtering effect into your audio signal.

Definition at line 53 of file juce_DelayLine.h.

## juce::dsp::DelayLineInterpolationTypes::Lagrange3rd

struct juce::dsp::DelayLineInterpolationTypes::Lagrange3rd

Successive samples in the delay line will be interpolated using a 3rd order Lagrange interpolator. This method incurs more computational overhead than linear interpolation but reduces the low-pass filtering effect whilst remaining amenable to real time delay modulation.

## juce::dsp::DelayLineInterpolationTypes::Thiran

struct juce::dsp::DelayLineInterpolationTypes::Thiran

Successive samples in the delay line will be interpolated using 1st order Thiran interpolation. This method is very efficient, and features a flat amplitude frequency response in exchange for less accuracy in the phase response. This interpolation method is stateful so is unsuitable for applications requiring fast delay modulation.
