- Reading a wav file with scipy and librosa in python
sig, rate = librosa load(spec_file) # rate 22050 sig = np array(α*sig, dtype = "int16") Something that almost worked is to multiple the result of sig with a constant α alpha that was the scale between the max values of the signal from scipy wavread and the signal derived from librosa Still though the signal rates were different
- audio - How to get complete fundamental (f0) frequency extraction with . . .
times = librosa times_like(o_env, sr=sr) onset_frames = librosa onset onset_detect(onset_envelope=o_env, sr=sr) Another view with power spectrogram: I tried compressing the audio, but that didn't seem to work Any suggestions on what parameters I can adjust, or audio pre-processing that can be done to have fundamental tones extracted from all words? What type of things affect fundamental tone

- Getting the frequencies associated with STFT in Librosa
When using librosa stft() to calculate a spectrogram, how does one get back the associated frequency values? I am not interested in generating an image as in librosa display specshow, but rather I

- How to calculate and plot multiple spectrogram in a for loop with librosa?
Is it possible to use librosa spectrogram instead of plt specgram?? @MalahatMehraban Does librosa have librosa spectrogram? I had a tiny look and I didn't see it but did see librosa melspectrogram? In case it is helpful, added code in my answer for using librosa to calculate the spectrogram No promises that it is an efficient way to do this :-)
- Plotting audio from librosa in matplotlib - Stack Overflow
y, sr = librosa load(<path_audio_file>, sr=<sample_rate>) fig, ax = librosa display waveplot(y, sr=sr) As it retains the sample rate as information, then it will normalize the time series at the right time length! Note that for using librosa display you need to explicitly import it If you're interested in more details check librosa display
