Impulse Response Files

The Top Convolution Reverb Plugins

If you’re unfamiliar with convolution reverb, we suggest reading this article: What is Convolution Reverb? In this article, convolution reverb is compared to traditional reverb.

Quick Definition of Convolution Reverb

Convolution reverb is a specific type of reverb effect that utilizes convolution technology to realistically reproduce the acoustics of an environment. Unlike traditional reverb algorithms that model the sound reflections of an environment, convolution reverb uses real audio recordings, known as impulse responses, to capture the acoustic characteristics of a room, studio, or any other system or environment.

Convolution reverb is also used to model other systems besides environments. It’s used, for example, to replicate the sound of tube amplifiers, speaker cabinets, or the acoustics of acoustic instruments.

When is it preferable to use convolution reverb?

Convolution reverb is preferable when a realistic reproduction of the acoustic characteristics of a space or system is necessary.

It is particularly useful for recreating real environments, allowing for the simulation of the acoustics of various spaces such as cathedrals, churches, halls, stadiums, etc. It greatly simplifies the reproduction of predefined environment characteristics.

Convolution reverb is also extensively used in cinematic, television, and video game post-production. Video games often draw inspiration from real-world environments, and convolution reverb helps simulate the sound ambiance of these virtual worlds based on existing environments. In cinema, post-production work involves manipulating the acoustic environment of scenes (deserts, forests, oceans, enclosed spaces, etc.).

In music, it is primarily used in studio recording or post-studio mixing. Convolution reverb simulates the acoustics of a space to add depth to recordings.

Convolution reverb is also employed in audio restoration to enhance the signal and achieve a higher-quality sound.

Top Convolution Reverb Plugins

Convology XT

The big advantage of Convology XT is that it’s free. It comes with about a dozen IR files. However, it’s possible to purchase additional impulse responses to add to the library. Additionally, it allows the import of third-party wav files. For beginners, this is undoubtedly the tool you need! To know more about Convology XT.

The Pros

Free
Some IRs included
Easy to use
No need to have a high performance computer
Mix between input and output sound

The Cons

Limitation in settings
You will have to buy more IR files

Altiverb

The Altiverb plugin is one of the benchmarks in the market. It’s one of the plugins we currently prefer. It’s ideal for working with impulse responses of environments. It contains a vast database of IR files integrated into the plugin and recorded in various environments (studios, halls, cathedrals, hangars, equipment, and many others). The plugin offers settings to imagine realistic acoustic spaces. To know more about Altiverb.

The Pros

Professional tool
Extensive database of impulse responses
Very advanced visualization
Intuitive user interface
Ability to position sound in space
One of the best

The Cons

Cost
Limitations in settings (compared to the plugin price)

SIR

A plugin that has been on the market for a long time and has gradually evolved positively. It offers a library of impulse responses and a wide range of settings (amplitude, early reflections management, compressor, equalizer, etc.) To know more about SIR3.

The Pros

Includes a database of impulse responses
Low CPU consumption and zero-latency processing
Great modulation parameters

The Cons

Limited library, but it’s easy to upload new files

Nugen Audio Paragon

A must-have for an audio professional! It is compatible with surround and Dolby Atmos usage. It works a little differently from previous ones with a system of decomposition and resynthesis of the submitted impulse response file. It has the usual settings. It is mainly aimed at the world of cinematic and television post-production. .

The Pros

Many settings to enhance sound richness
Is more for cinema/TV/video production

The Cons

Cost
Requires a great computer

Nugen Audio Paragon ST

Paragon ST is the little brother of the Paragon plugin. It is primarily aimed at music production. It is a stereo version of Paragon designed for a more musical usage. The Paragon ST plugin focuses on convolution reverb while preserving several characteristics of the Paragon software. To know more about Nugen Audio Paragon ST.

The Pros

Simplified user interface
High-quality sound with minimal adjustments
Clear value for money

The Cons

Simplified user interface
High-quality sound with minimal adjustments
Clear value for money
