[−][src]Trait basic_dsp::Convolution

pub trait Convolution<'a, S, T, C> where
    C: 'a,
    S: ToSliceMut<T>,
    T: RealNumber, {
    fn convolve<B>(
        &mut self, 
        buffer: &mut B, 
        impulse_response: C, 
        ratio: T, 
        len: usize
    )
    where
        B: for<'b> Buffer<'b, S, T>;
}

Provides a convolution operations.

Required methods

fn convolve<B>(
    &mut self,
    buffer: &mut B,
    impulse_response: C,
    ratio: T,
    len: usize
) where
    B: for<'b> Buffer<'b, S, T>, 

Convolves self with the convolution function impulse_response. For performance consider to to use FrequencyMultiplication instead of this operation depending on len.

An optimized convolution algorithm is used if 1.0 / ratio is an integer (inside a 1e-6 tolerance) and len is smaller than a threshold (202 right now).

Failures

TransRes may report the following ErrorReason members:

  1. VectorMustBeComplex: if self is in real number space overlap_discard impulse_response is in complex number space.
  2. VectorMustBeInTimeDomain: if self is in frequency domain.
