Function istft

pub fn istft<B>(
    stft_matrix: Tensor<B, 4>,
    window: Option<Tensor<B, 1>>,
    length: Option<usize>,
    options: StftOptions,
) -> Tensor<B, 2>where
    B: Backend,

Expand description

Computes the inverse Short-Time Fourier Transform (ISTFT).

Reconstructs a time-domain signal from its STFT representation using overlap-add.

§Arguments

stft_matrix - Complex STFT tensor of shape [batch, n_frames, n_freqs, 2].
window - Window tensor used in the forward STFT. Defaults to rectangular.
length - Optional output signal length. If None, the length is inferred.
options - STFT configuration (must match the forward STFT).

§Returns

A real-valued tensor of shape [batch, signal_length].
