ImportError: cannot import name 'Melspectrogram'

I believe this API is a deprecated, you will want to use ApplyFilterbank instead, from the docstring:

input_shape = (2048, 1)  # mono signal
n_fft = 1024
n_hop = n_fft // 2
kwargs = {
    'sample_rate': 22050,
    'n_freq': n_fft // 2 + 1,
    'n_mels': 128,
    'f_min': 0.0,
    'f_max': 8000,
}
model = Sequential()
model.add(kapre.STFT(n_fft=n_fft, hop_length=n_hop, input_shape=input_shape))
model.add(Magnitude())
# (batch, n_frame=3, n_freq=n_fft // 2 + 1, ch=1) and dtype is float
model.add(ApplyFilterbank(type='mel', filterbank_kwargs=kwargs))
# (batch, n_frame=3, n_mels=128, ch=1)

Is the following layer is the replacement? composed_melgram_layer = kapre.composed.get_melspectrogram_layer(input_shape=(44100, 1))

I am also looking for a compatible replacement for the Melspectrogram layer.

Any information is appreciated.

Yes, you’re right.
