What is an ARP file?
An .ARP file most commonly stores an Audition Replay File. The online dance game Audition Online, published by Redbana, uses this format to save and replay user gameplay.
However, an .ARP file can also be a project file for Meta Spark AR Studio. These files store augmented reality effects and patches. They often use a .ZIP or .JSON internal structure.
Other uses include AKINSOFT business reports, Arlequin population genetics data, ARPS construction cost estimates, or Nintendo DS cheat codes for the Action Replay system used in emulators like DeSmuME.
How to open ARP files?
To open an Audition Replay File, you must load it within the Audition Online game client.
To edit an augmented reality effect, open the .ARP file using Meta Spark AR Studio. Because these files use standard .ZIP or .JSON formats, you can also inspect them with standard text editors or archive extractors.
For cheat codes, use the DeSmuME emulator.
Because an .ARP file has multiple possible meanings, we recommend using viewer.online/arp to identify the actual format of your file.
Best practices and troubleshooting
viewer.online/arp can analyze .ARP files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
If you need a different format, you can convert your files. We recommend file conversion to sensible target formats on convert.guru. For example, you can convert text-based .ARP files to .TXT or .JSON.
Summary
An .ARP file serves different purposes depending on its origin, from gaming replays to augmented reality projects. viewer.online/arp is useful for identifying, inspecting, and understanding .ARP files without installing software or dealing with compatibility problems.
