QUESTION
I am trying to calculate the spectrogram out of .wav
files using Python. In an effort to do so, I am following the instructions that could be found in here. I am firstly read .wav
files using librosa library. The code found in the link works properly. That code is:
ANSWER
Answered 2019-Mar-06 at 14:06It may be because you've not tweaked the parameters of the librosa melspectrogram method.
In your original implementation you specify nfft=2048. This could be passed to melspectrogram and you will see different results.
This article describes 'waveform frequency resolution' and 'fft resolution' which are important parameters when doing a FT. Understanding them may help reproducing your original spectograms.

The specshow method has various parameters too which will directly affect the plots you're producing.
this stack posts lists the various spectogram parameters in MATLAB, but you can draw similarities between the MATLAB version and librosa version.

Install Speech-Process
You can use Speech-Process like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
