Struct WindowProcessor

pub struct WindowProcessor { /* private fields */ }

Provides fixed size windows extracted from a stream of arbitrarily sized input buffers. Supports downsampling and partially overlapping windows. Useful for implementing algorithms operating on consecutive windows of the same size.

Implementations

impl WindowProcessor

pub fn new( downsampling: usize, downsampled_window_size: usize, downsampled_hop_size: usize, ) -> Self

Creates a new WindowProcessor instance.

Arguments

• downsampling - The downsampling factor (1 corresponds to no downsampling)
• downsampled_window_size - The window size after downsampling.
• downsampled_hop_size - The distance, after downsampling, between the start of windows. Must not be zero and not be greater than downsampled_window_size.

pub fn reset(&mut self)

pub fn downsampling(&self) -> usize

Returns the downsampling factor.

pub fn downsampled_hop_size(&self) -> usize

Returns the hop size after downsampling.

pub fn downsampled_window_size(&self) -> usize

Returns the window size after downsampling.

pub fn process<F>(&mut self, buffer: &[f32], handler: F)

where F: FnMut(&[f32]),

Processes an arbitrarily sized buffer of input samples. Invokes the provided handler with each newly filled window.
