.aup File Extension

Developer: Audacity
File type: Project File
You're here because you have a file that has a file extension ending in .aup. Files with the file extension .aup can only be launched by certain applications. It's possible that .aup files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .aup file?

The AUP file extension is a data format associated with Audacity Project. AUP files and Audacity Project were developed by Audacity, a free sound editing and recording software. These files contain references and applied sound edits of audio files created in the Audacity Project. Specifically they store number of tracks, time positions, clip details, labels and volume automation. These files are saved in XML format and can be opened in a text editor. The Project consists of the AUP project file and a _data folder with sub folders in it. The a_data folder uses the DAT file extension and is ensured that they are in the same directory as the AUP files. It allows breaking of longer audio tracks to smaller pieces or chunks so the software open and save projects quickly. Files in AUP format can be opened with Audacity in Mac Os, Microsoft Windows based systems, and Linux.

how to open a .aup file?

Launch a .aup file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .aup file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .aup files aren't yet associated with it. In this case, when you try to open a .aup file, you can tell Windows which application is the correct one for that file. From then on, opening a  .aup file will open the correct application.

Audacity

Audacity

Audacity is a multilingual audio recorder and editor that is developed by a group of volunteers who are all a part of the audacity team. It is an open source software, in which the soure code is available to anyone who wishes to use or study it. Audacity is used mainly in live audio recording. Audio can be recorded with the use of microphones, line input or USB devices. It has a device toolbar that will help users manage numerous input and output deivces. To make multi-track recordings, users can dub over existing tracks. It has the capacity to record multiple channels at once and can record at high sample rates which are in excess of 192,000 Hz. Audacity can also be used in converting tapes and records into modern digital recordings and CDs. It has the ability to edit sound files such as Ogg vorbis, WAV, AIFF and MP3. Through the FFmpeg Library, AC3, M4A/M4R (AAC) and WMA can be imported and exported. The software also supports 16-bit, 24-bit and 32-bit samples. Sample rate and format conversion are performed using high-quality resampling and dithering. Users can also cut, copy, splice or make combination of sounds by mixing sounds together.

a word of warning

Be careful not to rename the extension on .aup files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .aup. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
