WebSorry for the confusion. Yes, simplified from my application-specific needs. Example features: if the input is a stereo signal, make it mono first; plot the spectrogram over a given frequency and time range; plot the log-spectrogram; round framesamp up to the nearest power of two; embed stft inside a Spectrogram class; etc. Your needs may differ. WebWarning. From version 1.8.0, return_complex must always be given explicitly for real inputs and return_complex=False has been deprecated. Strongly prefer return_complex=True as in a future pytorch release, this function will only return complex tensors.. Note that torch.view_as_real() can be used to recover a real tensor with an extra last dimension …
