A struct holding the parameters for interpolation.

Fields

sinc_len: usize

Length of the windowed sinc interpolation filter. Higher values can allow a higher cut-off frequency leading to less high frequency roll-off at the expense of higher cpu usage. 256 is a good starting point. The value will be rounded up to the nearest multiple of 8.

f_cutoff: f32

Relative cutoff frequency of the sinc interpolation filter (relative to the lowest one of fs_in/2 or fs_out/2). Start at 0.95, and increase if needed.

oversampling_factor: usize

The number of intermediate points to use for interpolation. Higher values use more memory for storing the sinc filters. Only the points actually needed are calculated dusing processing so a larger number does not directly lead to higher cpu usage. But keeping it down helps in keeping the sincs in the cpu cache. Start at 128.

interpolation: InterpolationType

Interpolation type, see InterpolationType

window: WindowFunction

Window function to use.
