![]() ![]() ![]() Then, we'll filter those down to only the type of file we want to convert - e.g. You can also use ls -Recurse if you want to recursively convert all files in subdirectories too. When working on experimental things, you might find yourself in a situation where you are faced with raw audio or video and need to modify it.Of course, now PowerShell has come along, specifically designed to make something exactly like this extremely easy.Īnd, yes, PowerShell is also available on other operating systems other than just Windows, but it comes pre-installed on Windows, so this should be useful to everyone.įirst, you'll want to list all of the files within the current directory, so, we'll start off with: ls Working with these media formats requires a few extra steps if you do not have suitable 3rd party software pre-installed, or perhaps you just prefer a command line approach for these operations? Either way, Python is a great tool for this job and next I will show you how. In my own situation, I wanted to experiment with some speech-to-text services, to test them for quality. ![]() I wanted to test specific audio files from youtube, then upload them to the speech-to-text app for transcription. To accomplish this, I used pytube to download the audio file, then ffmpeg library to converted the file to appropriate format, and finally ffmpeg to cut the audio file length - all using a command line! These are the commands I will discuss today. Choose your Linux distribution below and execute the installation commands. To get started, let’s first install these two packages in our system. Pip install pytube imageio imageio-ffmpeg PrerequisitesĮxecute this command to ensure you have all necessary modules installed. FFmpeg will extract the audio from the MP4 files, and Lame will encode it to the MP3 format. If you already have an audio file you want to work with, feel free to skip this first step. Otherwise, you can obtaining your audio sample from Youtube using pytube library. ![]()
