Audio IR is an Android app developed by Folus Wen. It falls under the category of Utilities & Tools. The app generates a waveform that can be used to send IR commands. To use the app, you need to create a simple circuit for the "Audio to IR" module. The app's initial configuration file supports devices such as Kolin (RC-207), Sharp (GA339WJSA), Samsung (AA59-00382A), Nikon (ML-L3), Sony (RMT-DSLR1), Canon (RC1), and Pentax (RC-F).

One of the best features of Audio IR is that you can update your IR command configuration file from the WINKIRC PC software. This app is free to download and use, and it is a great tool for anyone who needs to control IR devices. The app's design is simple and easy to use. The only downside is that you need to create the "Audio to IR" module by yourself, but it is a simple circuit that can be easily made.
