only.Expand description
The Inverse Modified Discrete Transform (IMDCT).
Implementations§
§impl Imdct
impl Imdct
pub fn new(n: usize) -> Imdct
pub fn new(n: usize) -> Imdct
Instantiate a N-point IMDCT with no scaling.
The value of n
is the number of spectral samples and must be a power-of-2 and less-than or
equal to 2 * Fft::MAX_SIZE
.
pub fn new_scaled(n: usize, scale: f64) -> Imdct
pub fn new_scaled(n: usize, scale: f64) -> Imdct
Instantiate a N-point IMDCT with scaling.
The value of n
is the number of spectral samples and must be a power-of-2 and less-than or
equal to 2 * Fft::MAX_SIZE
.
pub fn imdct(&mut self, spec: &[f32], out: &mut [f32])
pub fn imdct(&mut self, spec: &[f32], out: &mut [f32])
Performs the the N-point Inverse Modified Discrete Cosine Transform.
The number of input spectral samples provided by the slice spec
must equal the value of N
that the IMDCT was instantiated with. The length of the output slice, out
, must be of
length 2N. Failing to meet these requirements will throw an assertion.
