| function of dascore.transform.spectro | source |
spectrogram(
patch: Patch ,
dim: str = time,
**kwargs ,
)-> ‘PatchType’
Calculate a spectrogram from the patch data.
The output patch will have one more dimensions than the input patch.
| Parameter | Description |
|---|---|
| patch | The input patch |
| dim | The dimension along which the spectrograms are calculated. |
| **kwargs |
Passed to scipy.signal.spectrogram to control spectrogram options.See its documentation for options. |
