ltx23_upsample1d

Anti-aliasing 1D upsampler (transposed low-pass)

Description

Anti-aliasing 1D upsampler (transposed low-pass)

Usage

ltx23_upsample1d(ratio = 2L, kernel_size = NULL, window_type = "kaiser",
                 persistent = TRUE)

Arguments

  • ratio: Integer. Upsampling ratio.
  • kernel_size: Integer or NULL.
  • window_type: “kaiser” (BigVGAN default) or “hann” (final resampler).
  • persistent: Logical. Register the filter as a buffer (present in checkpoints); FALSE stores the computed filter as a plain field.
