I am using the librosa pitch shift method on an ecg.
pitch_shifting = librosa.effects.pitch_shift(ecg, 500, n_steps=100)
The ECG is segmented at 512 values per segment, thus window is 512. Librosa defaults to n_fft=2048. How can change this? the function doesn't accept n_fft as a parameter. Checking the docs and source code, it says find the **kwargs at librosa.decompose.stft which doesn't exist or couldn't find.
Please help, thank you!
