Struct rustdct::algorithm::Dst5Naive

pub struct Dst5Naive<T> { /* fields omitted */ }

Naive O(n^2 ) DST Type 5 implementation

This implementation is primarily used to test other DST5 algorithms.

// Computes a naive DST5 of size 23
use rustdct::Dst5;
use rustdct::algorithm::Dst5Naive;

let len = 23;
let mut buffer = vec![0f32; len];

let dst = Dst5Naive::new(len);
dst.process_dst5(&mut buffer);

Implementations

impl<T: DctNum> Dst5Naive<T>

pub fn new(len: usize) -> Self

Creates a new DST5 context that will process signals of length len

Trait Implementations

impl<T: DctNum> Dst5<T> for Dst5Naive<T>

pub fn process_dst5_with_scratch(&self, buffer: &mut [T], scratch: &mut [T])

Computes the DST Type 5 on the provided buffer, in-place. Uses the provided scratch buffer as scratch space.

pub fn process_dst5(&self, buffer: &mut [T])

Computes the DST Type 5 on the provided buffer, in-place.
