What is AUP?
AUP is Audacity Projects file. Audacity projects are stored in an AUP file, which is a format that has been highly optimized for Audacity so that it can open and save projects extremely quickly. In order to achieve this speed, Audacity breaks larger audio files into several smaller pieces and stores these pieces in a directory with a similar name as the project. For example, if you name a project 'chanson', then Audacity will create a project file called chanson.aup which stores the general information about your project, and it will store your audio in several files inside a directory called chanson_data. The Audacity Project format is not compatible with any other audio programs, so when you are finished working on a project and you want to be able to edit the audio in another program, you could export the project to WAV file.
What is MP4?
MPEG-4 Part 14, formally ISO/IEC 14496-14:2003, is a multimedia container format standard specified as a part of MPEG-4. It is most commonly used to store digital audio and digital video streams, especially those defined by MPEG, but can also be used to store other data such as subtitles and still images. Like most modern container formats, MPEG-4 Part 14 allows streaming over the Internet. The official filename extension for MPEG-4 Part 14 files is .mp4, thus the container format is often referred to simply as MP4.
MPEG-4 is a patented collection of methods defining compression of audio and visual (AV) digital data. It was introduced in late 1998 and designated a standard for a group of audio and video coding formats and related technology agreed upon by the ISO/IEC Moving Picture Experts Group (MPEG) (ISO/IEC JTC1/SC29/WG11) under the formal standard ISO/IEC 14496 - Coding of audio-visual objects. Uses of MPEG-4 include compression of AV data for web (streaming media) and CD distribution, voice (telephone, videophone) and broadcast television applications.
Can Audacity import or export formats like WMA, AC3 or Apple Music/iTunes files (M4A/MP4)? How can I export to formats not listed in the Export Audio Dialog? Why do exported files not include Album Artist or BPM metadata, Album Art or Lyrics? How to Convert MP4 or Any Video to MP3 Option 1: Using Audacity. Audacity is an open-source, multi-track audio editor and recorder for Windows, Mac OS X, GNU/Linux, and other operating systems. Way 3: How to Extract Audio from MP4 via Audacity. Audacity is a free and open source audio editor for Windows, Mac and Linux. You can extract any audio track from a MP4 video as MP3, WAV, FLAC and more for further editing. Moreover, you can apply audio-editing effects within Audacity as well. Step 1: Open Audacity.
MPEG-4 absorbs many of the features of MPEG-1 and MPEG-2 and other related standards, adding new features such as (extended) VRML support for 3D rendering, object-oriented composite files (including audio, video and VRML objects), support for externally-specified Digital Rights Management and various types of interactivity. AAC (Advanced Audio Coding) was standardized as an adjunct to MPEG-2 (as Part 7) before MPEG-4 was issued.
MPEG-4 is still a developing standard and is divided into a number of parts. Companies promoting MPEG-4 compatibility do not always clearly state which 'part' level compatibility they are referring to. The key parts to be aware of are MPEG-4 part 2 (including Advanced Simple Profile, used by codecs such as DivX, Xvid, Nero Digital and 3ivx and by Quicktime 6) and MPEG-4 part 10 (MPEG-4 AVC/H.264 or Advanced Video Coding, used by the x264 encoder, by Nero Digital AVC, by Quicktime 7, and by high-definition video media like Blu-ray Disc).

Audacity is an open source audio editing application that is available for Windows, Mac and Linux.
Now, for audacity to be able to convert an mp4 file, which is a video file to mp3, or any other audio file that is available for export, then you need to add the FFmpeg library in Audacity.
Then how do you do that.
You need to come to the Edit section on Windows and go to preferences.
If you’re on a Mac, it’s under the File tab here.
Just click on Edit because we’re on Windows and click on preferences.
And once we do that, we’ll need to navigate to the libraries section.
And you can notice that we have the lame mp3 export library. This is built into Audacity but if you’re using the old versions of Audacity, it’s not available.
The FFmpeg import and export library is also available.
But if it’s not available for you, then you need to click on the download button here.
And once you click on this download button, what happens is that it’s going to open up the FAQ section, “installing the FFmpeg import or export library”.
And you’ll notice what it tells you is that it allows you to import and export much larger range of audio formats, including m4a, aac, ac3, amr, and wma and also import audio from most video files.
Import Mp4 In Audacity
So basically, what you’re trying to do is you’re trying to use the FFmpeg library to help you import the video files into audacity, and then convert the video files into mp3.
So if you’re using Windows, you’ll need to come to this section.
For Mac, you go to the section and for GNU or Linux, you go to the section.
Just click on this for Windows.
And once you’re here, you can just click on the full instructions. Just click this.
If you don’t already have it installed, you can just click on this to download.
But if you need further instructions, you can just check from the section down here and follow along with this instructions is really going to work and help you a lot, especially if you want to do any extra editing of your audio files inside audacity, which is a very powerful audio editing application.
Now, since I already have it installed, I’ll just click on OK.
Now once I click on OK, I’ll navigate to the folder with the mp4 video file that I want to convert to mp3 and just click on it, drag and drop.
Now you’ll also notice there’s an m4a file here.
The reason why this is available, it’s also because without adding the FFmpeg library, it was not possible to import m4a files, which are very common nowadays with Camtasia because they don’t have the mp3 format.
Windows 10 Won't Play Mp4
So since we want to convert the mp4 to mp3, just drag and drop.
Once you drag and drop, it’s going to import.
Now once it’s imported, you’ll see the waveform appear here and since it is in stereo, then you’re going to see it here.
You can make any edits that you want to make to the audio.
Let’s say you wanted to remove a mistake to do things like normalization of the audio.
Let’s say you want it to be at zero dB.
To do some noise reduction, you can do any form of manipulation that you wanted here.
And once you’re satisfied, just come to the File, Export.
If you want to use Save as, Save as saves in the audacity, extension, but for the export is where you get to export to mp3, wav, ogg.
And if you decide to select as export audio, then here you have a bunch of extra options that you can do.
So we can click on this drop down and you’ll see all the different formats or audio formats that you can save to, but we’re interested in mp3.
You can check the bitrate mode to be constant at a quality of about 192.
The higher the better and the bigger the file size, but 192 kbps is good enough.
And once you’re satisfied, we can still rename this, let’s say
“converted from mp4.”
Just click on Save.
If there’s nothing that you need to change here, you just click on OK.
Once you click on OK, it’s exporting the audio at 192 kbps gives you the elapsed time and the remaining time.
So it’s almost done.
And once it’s done, we’re going to check it out.
So I already have the folder with the file here.
And you can see it here.
