Using it for other file types is also an improvement on my previous Audacity macro approach. This workflow meant I could convert all of the opus files I had. Lets explore another method if you didnt understand the first method to extract audio using FFmpeg. OGG works for Vorbis and WAV works for PCM. Among popular formats, Vorbis and PCM are two problematic formats. It converts it using our parameters and names the output file by switching the extension for mp3. Youll see the situation audio format not having a container named after it. Initially, an mp3 subdirectory is made, then ffmpeg receives the opus file via the quoted curly braces as an input. This one-liner will find (recursively) all. iname '*.opus' -exec bash -c 'D=$(dirname ".mp3"' \ Ĭredit to this StackOverflow answer.
