## Detailed Description

## Typedef Documentation

## ◆ WindowedSincInterpolator

using WindowedSincInterpolator = Interpolators::WindowedSinc

An interpolator for resampling a stream of floats using high order windowed (hann) sinc interpolation, recommended for high quality resampling.

Note that the resampler is stateful, so when there's a break in the continuity of the input stream you're feeding it, you should call reset() before feeding it any new data. And like with any other stateful filter, if you're resampling multiple channels, make sure each one uses its own LinearInterpolator object.

## ◆ LagrangeInterpolator

using LagrangeInterpolator = Interpolators::Lagrange

An interpolator for resampling a stream of floats using 4-point lagrange interpolation.

And like with any other stateful filter, if you're resampling multiple channels, make sure each one uses its own LagrangeInterpolator object.
