Struct imbe::spectral::Spectrals

pub struct Spectrals(_);

Spectral amplitudes M_l, 1 ≤ l ≤ L, measure the spectral envelope of the voiced/unvoiced signal spectrum.

Methods

impl Spectrals

pub fn new(
    coefs: &Coefficients,
    params: &BaseParams,
    prev: &PrevFrame
) -> Spectrals

Create a new Spectrals from the given DCT coefficients vector T_l and current/previous frame parameters.

pub fn get(&self, l: usize) -> f32

Retrieve the spectral amplitude M_l for the given l.

Methods from Deref<Target = ArrayVec<[f32; 56]>>

pub fn len(&self) -> usize

Return the number of elements in the ArrayVec.

use arrayvec::ArrayVec;

let mut array = ArrayVec::from([1, 2, 3]);
array.pop();
assert_eq!(array.len(), 2);

pub fn capacity(&self) -> usize

Return the capacity of the ArrayVec.

use arrayvec::ArrayVec;

let array = ArrayVec::from([1, 2, 3]);
assert_eq!(array.capacity(), 3);

pub fn is_full(&self) -> bool

Return if the ArrayVec is completely filled.

use arrayvec::ArrayVec;

let mut array = ArrayVec::<[_; 1]>::new();
assert!(!array.is_full());
array.push(1);
assert!(array.is_full());

pub fn as_slice(&self) -> &[<A as Array>::Item]

Return a slice containing all elements of the vector.
