Mastering Reverb Techniques

What is reverb? 

Have you ever noticed how sound behaves in different spaces? When you create a sound in an environment, not only does it travel directly to your ears, but it also dances off surfaces around you. This phenomenon is known as reverb, short for reverberation.

In essence, acoustic real-life reverb occurs when sound waves bounce off various surfaces in a given environment. Imagine standing in a room and clapping your hands. The sound doesn’t just reach your ears directly; it also bounces off walls, ceilings, and floors, creating a symphony of reflections. These reflected sounds blend with the original sound, forming what we perceive as an acoustic space that surrounds the primary sound source.

The environments we encounter daily are filled with surfaces that reflect sound. This abundance of reflective surfaces ensures that we’re constantly enveloped in a sea of sonic reflections. Our brains, remarkable as they are, instinctively work to make sense of this complex auditory information. Our hearing system group similar sounds together, which means that the reflections are perceived as part of the natural sound itself. 

Reverb isn’t just a sonic curiosity; it plays a significant role in our perception of the world around us. Different spaces produce distinct reverberation characteristics. Think about the contrast between the echoing grandeur of a cathedral and the intimate warmth of a small recording booth. Musicians, audio engineers, and even car-manufacturers and architects harness the power of reverb to create specific atmospheres and moods.

Why do you need reverb?

By infusing an audio signal with a sense of acoustic space, artificial reverb expands the realms of recording, granting affordability, control, and creative prowess. 

Reverb unfolds as an artistic canvas. Creating Cinematic Ambiance. It widens the scope of 3D virtual spaces,  harmonizing atmospheres, inviting experimentation with an array of sonic environments. Within the realm of popular music genres, reverb units craft treatments that transcend natural boundaries, and create identities and characteristic sound images.

Crafting Reverberation

The realm of artificial reverberation has undergone a transformative evolution, largely shaped by the prowess of digital technology. Microprocessors, adept at emulating the intricate dance of sound reflections. At its core, the replication of sound reflections essentially involves storing and summoning delayed audio, a task in which digital systems excel.  Nowadays we talk about binaural sounds through 3D sound localization and placing of sounds that feels incredible realistic. 

Reverberation Revelation

The choice between different kinds of reverbs, digital, plate, spring, echo chamber, IRs or analog, isn’t a mere binary; it’s nuanced tools offering sonic identities.

Digital technology streamlines the simulation of sound reflections with precision, while analog methods paint with the strokes of a rich, textured history. 

In the realm of mixing, reverb is used for gluing instruments together or enhancing tracks with acoustic characteristics.  It constitutes a medium of sonic vibrations and interference which creates the illusion that the instruments are in the same enviroment.

 

IMPULSE RESPONSES

Impulse response (IR) reverb is a type of digital reverb effect that simulates the acoustics of real spaces or hardware reverberation units. It uses recorded impulse responses to recreate the reverberation characteristics of specific rooms, space, halls, studios, or other environments. 

 

By using different impulse responses, you can simulate a wide range of acoustic environments, from small rooms to large concert halls, chambers, or even unique spaces with specific acoustic properties. Each impulse response captures the distinctive characteristics of the space, including its early reflections, decay time, frequency response, and spatial cues.

Placing instruments in distinct sonic environments sharpens the contrast between them. For instance, envision a scenario where a vocal resonates within a compact, brilliant room while a guitar reverberates within a cavernous, warm hall.

Why do my Wrongtools instrument have separate controls for ‘Pre-Delay’ and what do this do? 

The pre-delay control is a parameter that allows you to introduce a time delay between the original sound source and the onset of the reverberation. In other words, it determines the gap between when the direct sound is heard and when the reverb reflections begin.

By adjusting the pre-delay, you can manipulate the perceived distance between the listener and the reflective surfaces where the sound bounces off. A longer pre-delay setting creates a greater temporal gap between the direct sound and the onset of reverb, simulating the sensation of a larger or more distant space. On the other hand, a shorter pre-delay setting makes the reverb reflections almost immediate, creating the impression of a closer or smaller space.

The pre-delay can help in preventing the reverb from clouding the direct sound, allowing for greater clarity, especially in situations where the original sound needs to stand out.

WRONGTOOLS’ BONUS IR SETS

We love to make IRs, and experiment IRs while making music.  So we often make some of these that we think work well with the different libraries.  In some of our sample-libraries, you’ll also find an extra set of bonus-IR files.   

 

Many reverb plugins today offer the possibility to import these files.  With Logic Pro’s inbuilt Space designer you can simply drag them in to the window.  When you apply the effect to an audio track or mix, the plugin convolves the input signal with the loaded impulse response, creating the illusion of the sound being in the simulated space.

Most impulse response reverb plugins provide additional controls to adjust parameters like reverb decay time, pre-delay, wet/dry mix, and EQ. These parameters allow you to shape the reverb effect to suit your preferences and the specific audio material.

LOCATION OF THE IR FILES
Quick tip : Double check that the IR file is located in the session folder, then stores within your song session folder, so that it will load again in a future scenario when you have moved the sample-library to a new location. 

 

Exploring Alternatives to Reverb

When the allure of reverb finds alternatives, a world of sonic possibilities opens up, transforming your mix in unexpected ways. Equalization, for instance, emerges as a subtle sculptor of front-back perspective. Gently taming the high frequencies can mimic the air-damping phenomenon, mimicking the sonic journey from distant sources. A nuanced EQ approach, elegantly executed, can lend depth and spatial realism to your mix.

The ideal is a clear, distinctive and detailed listening setup. Muddy layers of reverbs are unnecessary and best eliminated.

With equalization, modulation, subtile pitch-shifting, compression, and a fusion of effects at your disposal, your mix can achieve dimensiontional depth. But a fair warning : it’s easy to get lost and blur the music with too much effects.  

A good rule of thumb can be to drag the effect further down 6-10dB when you are happy with the effect blend

 

Echoes of Emotion

As always, as long as things sound good, it sounds good.  Finding good reverb is a journey of creative exploration, guided by your musical vision.
