Description
With your video file selected in Finder, running this AppleScript will export the audio track as a 24bit, 48k .wav file in the same location. If more than one audio track is contained within the video file it will prompt you to select which one you’d like to export. If the audio track is of a higher channel count than 1/mono it will prompt you to select whether you want a single interleaved file (as it exists now in the video file) or as separate mono files.
IMPORTANT: PLEASE READ CAREFULLY
This AppleScript requires the free and open-source programs called FFmpeg and FFprobe to already be installed in one of two places on your computer before it can extract your audio. The two default locations are:
/usr/local/bin
/opt/homebrew/bin
If you already have them installed in another location on your computer you will be given the option of entering that location one time when the app is first launched.
If you do not already have FFmpeg and FFprobe installed please visit https://ffmpeg.org and click their “Download” link. From there you can choose the type of installation you prefer. If you are not sure you can simply click the “Static builds for MacOS 64-bit” and on that page click the “Download As Zip” in the upper left section under a file name similar to:
ffmpeg-123142-g22d484f498.7z
Choose a folder on your computer to download to and double-click the .zip file to extract the binary. Repeat these steps for the next row down to download FFprobe.
Once you have “ffmpeg” and “ffprobe” binaries on your local computer, you can type the following command in your “Terminal” app to create one of the two preferred locations:
sudo mkdir -p /usr/local/bin
Creating this folder will require you to enter your mac user password. Then type:
open /usr/local/bin
which will open a Finder window of this new folder where you can drag the two individual ffmpeg & ffprobe files from their download locations into this new location so my AppleScript can find them.
The first time you try to execute ffmpeg or ffprobe your Mac will likely give an error saying they do not have permission to run. You will need to go into your Privacy & Security panel, scroll to the bottom, and “Allow Anyway” where it tells you it was blocked.
