According to librosa.load documentation here, this method returns two things: The sample rate sr: which means how many samples are recorded per second. A 2D array: The first axis: represents the recorded samples of amplitudes (change of air pressure) in the audio.

$ conda create -n librosa_env python=3.6 Activate the environment: $ source activate librosa_env Then add the conda-forge channel (a repository that contains many libraries like librosa): $ conda config --add channels conda-forge Then install librosa: $ conda install librosa

This Python video tutorial show how to read and visualize Audio files (in this example - wav format files) by Python. For this reason librosa module is using the load function is not loading a mp3 file. The code : import os import librosa.

To confirm the previous answer, librosa.load returns a time series that in librosa glossary is defined as: "time series: Typically an audio signal, denoted by y, and represented as a one-dimensional numpy.ndarray of floating-point values. y[t] corresponds to the amplitude of the waveform at sample t." Loading your audio file : The first step towards our analysis is to load an audio library into our code.

librosa.load() function downmixes to mono by averaging left- and right-channels, and then resamples the monophonic signal to the default rate sr=22050 Hz. Most audio analysis methods operate not at the native sampling rate of the signal, but over small frames of the signal which are spaced by a hop length (in samples). The

The default frame and hop Parameters: y: np.ndarray [shape=(2,n) or shape=(n,)]. audio time series, either stereo or mono. Returns: y_mono: np.ndarray [shape=(n,)].
