Reverberation occurs when sound waves are produced in a room and reflect off surfaces in all directions. These reflections decrease in amplitude until they eventually fade away. In most rooms without extensive sound insulation, many closely-spaced reflections reach the listener shortly after the direct sound. We perceive this series of reflections as a continuous, single sound known as "reverberation."
Understanding the type of music you're creating and the desired sound is crucial for adding depth during mixing and mastering. Knowledge of reverb can also guide you in choosing the right room for recording your music.
We'll begin by examining how sound forms and changes in real spaces. Next, we'll explore how reverb plug-ins and external devices emulate real rooms or hallways using a technique known as convolution reverb. Finally, we'll discuss how various tools, including plug-ins, hardware, metal springs, and plates, can create artificial spaces and sounds to enhance your audio.
By the end of this article, we hope you'll feel comfortable with the different types of reverb, both natural and artificial.
Reverb in music production can be created either through mechanical or acoustical methods. However, modern productions often prefer digital reverb for its control and flexibility. Let's dive into digital reverb.
Digital reverb can be classified into two main types: convolution and algorithmic.
Algorithmic reverb replicates reverb through a series of calculations (algorithms). By mathematically creating reflections, you can mimic the sounds of real spaces or design new sound environments that wouldn't be possible otherwise. Examples include:
Convolution reverb, also known as IR or sample reverb, processes an impulse response (IR) recording of a signal played in a real space or through a device. This captures the full acoustic response of the room. Convolution reverbs can make audio sound as if it were recorded in real spaces, such as the Sydney Opera House. Examples include Audio Ease AltiVerb 7 and HOFA IQReverb.
Digital reverb offers customization options. Common controls include:
Pre-delay: The time between the direct sound and the start of the initial reflection. Larger rooms have longer pre-delays due to the greater distance sound must travel.
When discussing "types of reverb sounds," we're referring to the methods by which reverb is created. Let's look at some examples:
Hall Reverb: Mimics the characteristics of a concert hall, with long, smooth decay.
Room Reverb: Reflects the properties of a smaller room, with shorter decay times and closer reflections.
Plate Reverb Created by vibrating metal plates. A dry signal is sent to a driver that causes the plate to vibrate, with contact microphones picking up these vibrations.
Spring Reverb: Produced by a small spring vibrating. Similar to plate reverb, a transducer causes the spring to vibrate, with another transducer detecting the vibrations at the other end.
Reverb techniques and effects are prevalent in modern productions. Here's a quick look at their use:
Treat reverb as a new signal in the mix, ensuring it complements other elements.
Use a return/aux channel for reverb, keeping the dry/wet balance at 100% wet.
Separate wet and dry signals to process them independently.
Reverb on Drums
Consistency is key; using a single reverb for the entire drum kit can help.
Avoid reverb on kick drums to prevent muddiness.
Lower the reverb signal for transient drum sounds to maintain their impact.
Voice Reverb
Adjust reverb based on the desired vocal sound. For example, shorter reverb tails for a rap sound or longer ones for a more spacious effect. Consider genre-specific reverb standards, like spring reverb in dub and reggae. Reverb in Post-Production and Other Audio Projects
In post-production, reverb is used extensively for TV, movies, short films, and podcasts. Automation plays a significant role, as reverb character, decay time, and panning can change with scene movements.
Sometimes, you need to remove unwanted reverb from recordings. This is crucial for achieving a clean mix, especially if the room noise is prominent. Minimizing built-in reverb helps avoid creating a muddy mix when adding your own reverb effects.
Experimenting with reverb can unlock new sonic qualities in your music. Try using it in mono, stereo, and with extreme settings. Listen for natural reverb in your environment and incorporate those inspirations into your work.
If achieving effective reverb proves challenging, consider using an online music production company like Carry A Tune for professional assistance in sound mixing online. Their expertise can help you craft your next hit with clarity and depth.For more comprehensive insights, refer to our recording mixing mastering tips
