`transform_sliding_window_cmn.Rd`

Apply sliding-window cepstral mean (and optionally variance) normalization per utterance.

```
transform_sliding_window_cmn(
cmn_window = 600,
min_cmn_window = 100,
center = FALSE,
norm_vars = FALSE
)
```

- cmn_window
(int, optional): Window in frames for running average CMN computation (int, default = 600)

- min_cmn_window
(int, optional): Minimum CMN window used at start of decoding (adds latency only at start). Only applicable if center ==

`FALSE`

, ignored if center==`TRUE`

(int, default = 100)- center
(bool, optional): If

`TRUE`

, use a window centered on the current frame (to the extent possible, modulo end effects). If`FALSE`

, window is to the left. (bool, default =`FALSE`

)- norm_vars
(bool, optional): If

`TRUE`

, normalize variance to one. (bool, default =`FALSE`

)

Tensor: Tensor of audio of dimension (..., time).

forward param: waveform (Tensor): Tensor of audio of dimension (..., time).
