What is an ADTS File?

How to Open, Edit, & Convert ADTS Files

A file with the ADTS file extension is an Audio Data Transport Stream file. This file format stores sections of an audio file in various frames, each of which include the audio data and header information. AAC files streamed online are often transferred in the ADTS format.

Some ADTS files may be text files from Autodesk's AutoCAD software.

Note: Some ADTS files may use the .ADT file extension. However, ADT is also the file extension used for ACT!

Document Template files and World of Warcraft Map files.

How To Open an ADTS File

You can play ADTS audio files with Windows Media Player, VLC player, and probably also some other popular media player applications.

Autodesk's AutoCAD software can create ADTS files from an "AUDIT" command for troubleshooting purposes. These are text-only files that can be opened with a text editor like Notepad++.

Note: Do you have an ADT file? If it's not an audio file, it may be an ACT! Document Template file used with the Swiftpage Act! software. Another possibility is that the ADT file is used with the World of Warcraft game as a format for storing information on objects and maps.

If you find that an application on your PC does try to open the ADTS file but it's the wrong application or if you would rather have another installed program open ADTS files, see my How To Change the Default Program for a Specific File Extension guide for making that change in Windows.

How To Convert an ADTS File

A free file converter like Freemake Video Converter (which supports video and audio formats) can convert an ADTS file to another audio format like MP3, WAV, etc.

AutoCAD ADTS files can be saved to a different text format with a text editor/viewer like Notepad in Windows or the free Notepad++ program I mentioned above.
