The next three factory presets: Room – 1, Studio – 1, and Plate – 1 are from the Waves basic IR library. This IR Library is available with any install of the IR-1plug-in.
Most Factory Presets offer two load options:
•Impulse Response and Reset
•Impulse Response
The first option will load the IR and reset all parameters to their default state. The latter will load the selected preset’s IR into the current setup, automatically applying the current parameters to the newly loaded IR.
Again, you can audition the pure convolution using the original impulse response by loading the “IR-1 Full reset" factory-preset (or the "Impulse Response and Reset" option in each IR sub-menu), and setting Wet/Dry to 100% wet and Direct On/Off to On.
The Impulse Responses supplied with the IR-series include the product’s basic IR set and two IR Libraries on CD’s. This gives you almost One Gigabyte of Impulse Responses with 32-bit 96kHz quality.
The IR library is installed into the Waves Plug-Ins folder in a sub-folder called IR1Impulses. The Impulse files are stored in a proprietary Waves format and use the extension .wir (Waves Impulse Response). The .wir files cannot be opened in normal Audio Editors, but they can be imported into the IR-1.
Saving
The Save operation will always save all data: Control Settings, IR properties and a pointer to the IR file. This is true whether saving to a new file or to a user preset.
The impulse response data is stored in a .wir file, separate from the IR-1 .xps preset file. The .xps preset file contains the file name of the relevant .wir file. A complete preset is valid only if the related .WIR file is found. In the event that the .wir file specified in the preset is not found, a dialog box saying: “Please locate: Filename” opens. You can browse and navigate to the file, point to a different file, or cancel.
Canceling returns to the plug-in without loading a setup and will show a message “IR was not loaded”. Pointing to a different file will load that file in place of the one saved with the preset, and a note on the IR Graph “Different IR loaded to preset” will be displayed.
