typecast error 'int 16' not supported #162

in nikl_m.py

mel_spectrogram = audio.melspectrogram(wav).astype(np.float32)

example here from nnmnkwii.util import example_audio_file

from scipy.io import wavfile fs, x = wavfile.read(example_audio_file()) >>> x = x.astype(np.float64) from nnmnkwii import preprocessing as P y = P.preemphasis(x, coef=0.97) assert x.shape == y.shape

first I faced with audio read no backend error ... I thought that was codec error and had hard time debugging but it was just simple error... That type cast should be done earlier converting numpy to float parameter. wav = audio.load_wav(wav_path) wave = wav.astype(np.float32) spectrogram = audio.spectrogram(wave)

I wonder it can be just version problem
