You can also automatically split MP3 or WAV files into equal-sized parts. The program can quickly split or cut large MP3 or WAV files without re-compression. Direct WAV MP3 Splitter v.2.2.0.0 Direct WAV MP3 Splitter is a fast automatic WAV and MP3 cutter.When used as an output option (before an output url), stop writing the output after its duration reaches duration. Here is the relevant passage from the ffmpeg documentation: $ ffmpeg -i source_audio_file.mp3 -ss 240 -t 120 segment_3.mp3 $ ffmpeg -i source_audio_file.mp3 -ss 120 -t 120 segment_2.mp3 t reflects the duration of the resulting audio file, not the ending time stamp.Īllan's sample code should read: $ ffmpeg -i source_audio_file.mp3 -ss 0 -t 120 segment_1.mp3 Note that the format of two lines that Allan provided in their answer is incorrect.Īfter several hours of troubleshooting my AppleScript file, I realized that my AppleScript file was not the issue. But, fortunately, the user can simply set it, and direct their attention to something else as it completes. This is because ffmpeg is slow at re-encoding. Note that when the user does not choose the source bit rate as the bit rate for the resulting files, the script can take a while. Using the linked script, the user can intuitively split up any audio file into numerous files based on a defined interval, while requiring minimal time and effort from the user. You can view and download the full code on this Pastebin page. The length of the code exceeds the maximum character limit for Stack Exchange answers. I am not able to paste the entire script directly in this answer. It would be somewhat complicated to write, since not all audio formats can be encoded in VBR (only Opus, Vorbis, MP3, WMA, and AAC audio files can).įinally, I am 100% certain that the code contains at least some shortcomings, blind spots, and/or bugs, so I apologize in advance. I chose not to do so because, for my purposes, this ability is not particularly needed. It is entirely possible, if laborious, to program a VBR (variable bit rate) encoding option for the resulting files into the script. In that case, you might want to adjust the app so that the user can simply drag the source audio file onto the app icon to initiate the app (instead of having to provide the file path of this file in a dialog).If you prefer to convert this script to a launchable, standalone application, you can easily do so in Automator (by inserting a "Run AppleScript" action into your workflow and pasting the full code). scpt file created in Script Editor is fine by me. I don't envision myself needing to do this audio splitting task that often, so a simple. I've done my best to include some error handling to catch certain potential errors, but this is obviously far from all-inclusive. Now, you will be able to make use of my script.Įven though this was not totally necessary for my purposes, ffmpeg also provides the user with total control over filenames, file types, bit rate, the output directory, etc., which is gravy.Ĭertain aspects of my script are tailored to my personal preferences (e.g., including the current date in the name of the output directory), so obviously modify the code as you see fit. Homebrew is very easy to install directions can be found at the top of this page (the official Homebrew website).Īfter installing Homebrew, run these lines individually in Terminal to install ffmpeg on your system: brew install ffmpeg Note: If you do not have ffmpeg currently installed on your computer, my script is worthless. It makes use of ffmpeg, as suggested in a previous answer by user Allan. I've written an AppleScript that will accomplish exactly what I described in my original post. There are various methods to accomplish what I want in Microsoft Windows, but can this be done on a Mac? The most important condition is that the method requires minimal time and effort from the user. I do not want the originalAudioFile.m4a to be altered in the process. A minor loss in audio quality is not a big deal (but this would obviously not be preferred). I'm just looking for a quick and handy way to split an audio file based on a specific interval. This is not a situation where the resulting audio files will be mastered to a CD or something. I am not particular about the file types of the resulting files (e.g., whether they become. I am not particular about the filenames of the resulting files. I would like to split this audio file into a separate audio file every 2 minutes.ĪudioFile1.m4a is created from to ofĪudioFile2.m4a is created from to ofĪudioFile3.m4a is created from to ofĪudioFile23.m4a is created from to of I have a 45 minute long audio (.m4a) file.
