What is an IRS file?

IRS files mostly belong to foobar2000. IRS files are mainly used to store impulse response data in a RIFF container. This means the file holds a digital recording of a space’s acoustic response used in audio processing.
Depending on the source, an IRS file can be one of several types:

Impulse Response Audio: The file holds measurements for simulating reverb and room acoustics. Open these with a digital audio workstation or a convolution reverb plugin.

Game Level Data: In other cases, an IRS file contains level or scenario info for Unreal Engine 4 projects. For such files, the Unreal Engine editor is required.

Tax Form File: Some files with the IRS extension are used by tax preparation software (like TaxAct or TaxWise) to store IRS tax forms. These are managed with dedicated tax software. See the TaxAct website for details.

FilExt.com tip: Since the same extension is used across different fields, ensure you know the file’s origin to choose the proper software for opening and viewing.

If you cannot open your IRS file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a IRS file directly in the browser:.
