We will start by importing the libraries. You can use a text editor or Jupyter Notebook. In case you are having issues when installing moviepy library, make sure the ffmpeg library is installed correctly. MoviePy is a library that can read and write all the most common audio and video formats, including GIFs. Write the following line in your terminal window: pip install ffmpeg moviepyįfmpeg is a leading multimedia framework, that decodes, encodes, transcodes, mux, demux, stream, filter and play pretty much anything that humans and machines have created. You can even install a couple of libraries in one line of code. For instance, if your sound is represented have a Nx2 Numpy array of integers, you will just write 1 audioarray.astype('int16'). Now you just have to write raw audio data into the file. For some codecs providing the output bitrate is optional. Installing a module library is very straightforward in python. sudo apt-get install vlc sudo pip3 install python-vlc Playing from Python worked straight forward: import vlc instance vlc.Instance ('-aoutalsa') p diaplayernew () m dianew ('something.mp3') p.setmedia (m) p.play () p.pause () vlc.libvlcaudiosetvolume (p, volume) volume 0. The codec can be any valid FFMPEG audio codec. If you are ready, let’s start by installing the libraries! Using a library called MoviePy, we will extract the audio from the video recording. It can even be a short recording of yourself speaking to the camera. Let’s get started!Īs you can understand from the title, we will need a video recording for this project. Before moving to the programming part, I would like to give some information about the library we will use in this project: MoviePy. It will not take us more than five minutes to finish the whole project.
