Module microdsp::common

Common algorithms and utilities.

Structs

WindowProcessor

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.

Enums

WindowFunctionType

Window function type.

Traits

F32ArrayExt

DSP related [f32] extensions.

Functions

apply_window_function

Performs point-wise multiplication of a buffer and a window function of a given type.

autocorr_conv

Computes the autocorrelation of a given buffer using time domain convolution.

autocorr_fft

Computes the autocorrelation of a given buffer using FFT.

autocorr_fft_size

Computes the length of the FFT needed to compute the autocorrelation for a given window size and lag count to avoid circular convolution effects.

freq_to_midi_note

Converts a frequency in Hz to a MIDI note number (with a fractional part).

real_fft

Perform an in-place fast Fourier transform on real valued data. Input buffer length must be a power of 2.
