01Overview

IR1A Convolver uses impulse response files to transfer the character of one sound onto another. The developer describes the engine as zero-latency and CPU efficient, and it can reproduce sources ranging from guitar cabinets to natural-sounding reverbs and special effects. Impulse responses can run up to 10 seconds at a 44.1 kHz sample rate. Predelay, high and low pass filtering, and a phase switch give you control over how the loaded IR sits in your mix.

Sound Shaping With Impulse Responses

The plugin loads standard mono or stereo AIFF or WAV impulse response files. Once an IR is loaded, its sonic signature is applied to the incoming audio. Predelay adjusts from 0 to 250 milliseconds, letting you separate the dry signal from the start of the response. High and low pass filters let you trim the frequency range of the IR, which is useful for taking low-end or harsh highs out of a reverb tail.

IR lengths can be set, and the internal processing runs at 64-bit for the audio path.

Browsing and Loading IR Files

An integrated file browser lets you navigate your IR library and load files without leaving the plugin. You can also import external IR files from other locations on your drive. Customisable image previews help you identify a response visually, and a starter library of presets is included to begin with.

The plugin is offered in VST3, VST2, AU and AAX formats on Windows 10 and later and macOS 10.9 and later. A trial version is available.
