Struct FftStage 

pub struct FftStage {}

Forward FFT stage: real time-domain samples to complex frequency-domain.

The output block stores interleaved [re, im, re, im, ...] pairs. The block size must be a power of 2.

When the gpu feature is enabled, set gpu to true to dispatch FFT through grafos-tensor’s GPU path. Falls back to CPU if the tensor cannot be placed on GPU.

Implementations

impl FftStage

pub fn new() -> Self

Create a CPU-only FFT stage.

pub fn with_gpu() -> Self

Create an FFT stage with GPU dispatch enabled.

When the gpu feature is not compiled in, this is identical to new().

Trait Implementations

impl Default for FftStage

fn default() -> Self

Returns the “default value” for a type.

impl DspStage for FftStage

fn process(&mut self, block: &Block) -> Result<Block, FabricError>

Process a block of samples, returning a transformed block.
