You can import IR files using an Impulse Responses Loader plugin in your DAW. 2. Locate the IR folder. A file pathway usually looks like this: Documents -> Ableton -> Factory Packs -> *IR Pack Name* -> *IR Pack Effect Name* -> Convolution Reverb -> IRs 3. Simply Drag and Drop impulse responses from the IR loader to your channel tracks. 4. Make custom presets of your go-to impulse responses so that you don't need to search them on your hard drive each time you open a new project in your DAW. 5. Don't fret over the sample rate of your newly loaded impulse responses. You IR files usually will have different sample rates. That problem is taken care of by the plugins (IR Loader/Convolution Reverb) as they convert your IR files' sample rate.
