Trait basic_dsp_vector::Convolution

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