B2 by 2CAudio Review

Looking for reverb with excellent sound, natural to use and if needed an immense scope of control? How about two independent reverb engines plus a saturation and limiter unit? Need plenty of presets to get started?

After this engaging introduction, you know what B2 by 2CAudio is capable of doing for you.

2CAudio develops audio plug-ins in VST, AU, and AAX formats. Their focus is on spatial processing and advanced creative effects. 2CAudio did send a review copy with no strings attached.


2CAudio has released an algorithmic reverb B2 which comes with a dual reverb engine that is flexible and comes with additional effects to shape the resulting reverb effect. With the saturation effect, you can add implied saturation or take the whole track into an ultimate bit-crushing land.

B2 produces excellent sounds and is an excellent choice to add body to specific sounds. B2 can be used to inject live and movement and is an excellent tool for generating harsh environment.

B2 can be CPU intensive, you will find out if you would need for sketching use the B2 reverb at lower CPU demanding settings, and when you are ready to print the stems switch to higher quality modes and oversampling.

B2 by 2CAudio Presets

2CAudio reports a lot of presets, you receive:

  • 672 Factory Presets in 25 classes
  • 96 Dynamics Presets in 7 classes
  • 54 Engine Templates in 8 classes
  • 319 Engine Presets in 12 classes from Breeze 1.1

To expand the Preset, you can at a cost add expansions:

B2 offers according to 2CAudio 36 damping, 30 EQ filter choices, 33 Attitude types, 4 Attitude routings, 4 Density modes, 12 Contour modes, 2 Modulation modes, 3 Modulation densities, 4 Dynamics modes, 4 Dynamics routings, two different spatial modes, and four delay feedback/Time modes. All said it means that you get plenty of tools and effects to shape the sound as needed or take the tone into sound design levels to develop and mangle it.

User interface & Usability

It has a UI that shows its age. Even when from a design point of few several years old, 2CAudio found a way six years ago to come up with an Interface that allows you to get started and make adjustments quickly. It still feels fresh, a pleasant surprise.

Rating:  Five out of five stars

B2 reverb offers that great dual-reverb with an additional effects engine that makes it unique. The resulting character of the B2 sound is entirely excellent. Starting with a preset and drive the whole track or mix bus to the new limits with the combinations that are available. B2 is a fabulous sounding algorithmic reverb.

2CAudio Releases PBJ Spatial Mixing Environment, Precedence 1.5 & Breeze 2.5




PBJ Spatial Mixing Environment, Precedence 1.5 & Breeze 2.5


2CAudio Releases PBJ Spatial Mixing Environment, Precedence 1.5 & Breeze 2.5 50

The PBJ Pack is a Spatial Mixing Environment that combines sublime psychoacoustic positioning and industry-leading algorithmic reverb into a unified and intelligently adaptive workflow. It introduces a unique system of multi-instance editing and inter-plugin communication that allows potentially hundreds of linked plug-in instances to function as a unified acoustic space, where each instrument can occupy its own unique position within this cohesive virtual acoustic environment.

Precedence handles the more local and relative perceptual cues while the reverb engine handles more absolute global environmental aspects. Together they synergistically complete the spatial illusion and achieve new levels of realism. Achieving a cohesive spatial mix with individual track separation, definition, and perfect depth placement has never been this easy!

The PBJ Pack is comprised of Precedence 1.5, Breeze 2.5, and 4 Breeze Preset Expansions.


Precedence 1.5 is a psychoacoustic stereo positioning tool. It creates an organically modulating stereo-image that produces an instantaneous sense of width, depth, and presence similar to stereo microphone techniques used in acoustic spaces. It then positions this image within a virtual stage, giving mix engineers ultra precise control over left-to-right and front-to-back placement. The end result is an incredible sense of hyper-realistic 3D space and specific localization of each instrument within this space.

2CAudio Releases PBJ Spatial Mixing Environment, Precedence 1.5 & Breeze 2.5 51


Breeze 2.5 is an industry-leading algorithmic reverb that is ultra-efficient, simple to use, and most importantly sounds absolutely sublime. In its most recent version, it has also grown to become one of the most powerful spatial tools on the market! Breeze 2.5 introduces a completely novel Distance-Link DSP mode, where the entire algorithm retunes itself based on instrument position, effectively producing a different set of impulse responses for an infinite number of positions within the virtual room.

2CAudio Releases PBJ Spatial Mixing Environment, Precedence 1.5 & Breeze 2.5 52


The PBJ system is a new paradigm in spatial mixing. It pairs direct sound spatialization and positioning with an adaptive multi-instance reverb environment that automatically tunes itself to augment the positional imaging established by Precedence.

The Following features form the basis of the PBJ system

2CAudio Releases PBJ Spatial Mixing Environment, Precedence 1.5 & Breeze 2.5 53
  • Link instances of Precedence and Breeze via Inter-Plugin Communication
  • Establish a unified spatial environment with Breeze, and use Precedence to place individual tracks within this environment
  • Automatically make very complex adjustments to internal Breeze DSP settings simply by changing position information in Precedence
  • Achieve never-before-heard levels of realism in-depth and azimuth positioning
  • Distance Link DSP mode adjusts automatically adjusts hundreds of internal DSP values within the Breeze Alg in response to changes to the single Distance parameter
  • PreDelay, Direct/Reflected Energy Balance and many more parameters become responsive to Distance which can be linked to Precedence
  • A single Breeze Preset no longer represents a single position within a space, but rather the entire space with an infinite variety of positions created within this space
  • Effectively an Algorithmic equivalent of having infinitely many impulse responses of a given acoustic space
2CAudio Releases PBJ Spatial Mixing Environment, Precedence 1.5 & Breeze 2.5 54
  • Manage many instances of Precedence and Breeze within a single GUI window
  • Use the Precedence Position Display to visualize position information for all tracks in an Edit Group simultaneously.
  • Edit parameter and preset data for any instance within and Edit Group
  • Multi-Instance Edits performed in Precedence change linked Breeze Instances as well
  • Speed up your workflow and eliminate the need to open and close GUI windows one at a time


  • Organize and Group many instances of Breeze into edit Groups to manage complex sessions
  • Allow some instances to work independently without Groups if desired, for send buses


  • Make macro changes en mass to an entire group of 10s or 100s of instances!
  • Apply preset and parameter changes to all instances within an Edit Group!
  • Change the spatial mixing environment for an entire mix in a single click while maintaining relative track positions
  • Change the existing positioning laws in Precedence en masse to adjust spatial contrast in established mixes
  • Allow individual variations for each track to enable micro-management of individual track details when needed
  • Allow Randomize to create randomized preset variations for an entire group that remain part of the unified space


Lock multi-instance selections to Precedence to allow Precedence to function as the command center for Multi-Instance mixing


  • 3 Algorithm Modes in Precedence:

    Beta: the default mode providing the most specific positioning using a full set of psychoacoustic principals
    Mu: an enhanced mono-compatibility mode for cases where this is a critical concern
    Omega: an enhanced diffusive model with extra widening designed for synths and modern FX​
  • Precedence X-Range Loss Mode: allowing more extreme Gain and High-Frequency Loss to exaggerate the sense of distance for use in Post Production SFX
  • Precedence Input Channel Swap to more easily align sample libraries that have been recorded In-Situ with the final desired position

Creating Depths with BREEZE2



Breeze2 1

Creating Depths with BREEZE2

Creating “acoustic depths” is especially needed for natural-sounding mixes of orchestras.

orchestra setups6
Orchestra Setups

You may want to place your instruments, as you can see in the picture above. Set Left and Right with the balance knob. But how does one “push” an instrument back or forward?

Breeze2 Fereatured

This can be done by using a reverb plug-in.
“Yes, I know”, you say, “but I do not want more reverb, just push the instrument back, it never works for me.”

Breeze2 Part 2

Here’s a guide on how to do it with BREEZE2:

If you like, download some Orchestra Audio Tracks from here. Willem Defesch “Sonata” could be good for this experiment. Insert all the Audio-File Solo Violin into your DAW and insert BREEZE2 (See also our Breeze 2 by 2CAudio Review) into the effect section.

breeze2 video a

Select the preset: F1 Factory Current / The Med Hall B
Change the following:
Pre Delay = 0ms
Time = 1.0 – 1.2
Now you can push your instrument backwards and forwards with Dry / Wet.

By the way: You get a 3D effect when you press “MIX”“. Then the word MIX changes to BALANCE.

Now you can use the Width controller to adjust the 3D effect. “66% width” is probably enough.

BREEZE2 Den Med Hall B

Of course, the “Den Med Hall B” preset is not optimal for our recorder. It sounds too big in the distance because it was taken close. For a more natural reverb sound, you have to dampen the low frequencies a bit. I chose the bandpass in Breeze2 (blue curve).

Remember the following:
Instruments that sound far away can not be far left or right. So the farther away instruments are the more they sound from the middle.
Also: The used preset is only to be understood as starting point. The goal is to have as many early reflections as possible. = nice depths.

How does it sound?

The distance depends on the ratio “dry/wet”
This is how BREEZE 2 sounds with the modified “Den-Med-Hall-B” preset:

This is how BREEZE 2 sounds with the additional adapted bandpass EQ:

728x90 4

And the final mix…There are only 4 audio tracks in the Willem De Fesch Sonata:

  • 1 recorder
  • 2 organ high
  • 3 organ low
  • 4 cello
    I summarized the organ in a group track.
Breeze2 And the final mix… defesh projekt2018
And the final mix…

This is the “virtual stage” I tried to achieve with the mix.

BREEZE2 virtual stage
virtual stage

The organ at the back, far away, the cello back, because it actually belongs to the basso continuo (organ) and then the flute prominently in front of me the listener.
This makes sense because actually, the fetus is a lly instrument, which may be quiet something close to the listener.
Of course, everything is over the top, but BREEZE 2 does a pretty good job.


Without any effect 


Using all this for an Orchestra… I tried to recreate this virtual stage acoustically

2CAudio Breeze 2.1 Update



Precedence by 2CAudio and Breeze 2.1

Breeze 2.1 offers some very significant improvements including P-Link Mode, Chameleon Color GUI System, Sub-Zero Suspend-On-Silence CPU-Saver, 3 New Filter Types for Damp and EQ, and more. Breeze 2.1 update connects with the new Precedence spatialization, and positioning plugin see our Precedence review here. See our Breeze 2 Review here if you want to learn more about the effect plugin.

Breeze2 UI

Breeze 2.1 New Features & Changes:

  • P-Link Mode
  • Chameleon Color GUI
  • Suspend Processing On Zero Input
  • 3 New Filter Types
  • Improvement to Early Phase Response
  • Phase Inversion Button
  • Channel Swap Button
  • Other Misc Tweaks
  • New Presets

Below you find the description direct from 2CAudio on some of the new changes.

P-Link Mode

When Using P-Link Mode Pre-Delay is set automatically as a function of Mix/Balance, Size, and the current Algorithm Mode. Additional behind-the-scenes, secret-sauce changes are made as well, so that the Mix/Balance control can effectively be thought of a “Distance Control”.

In real acoustic environments, sounds that are closer to the listener are likely to have MORE pre-delay, and LESS reverb energy relative to the source sound energy. Therefore there should be an inverse relationship between Mix and Pre-Delay in most cases to agree with behavior in the real world, but that is not widely understood in the community, so we can now set this up appropriately for you automatically. In this mode, the standard Pre-Delay control is replaced with the “PD Adjust” control which allows some manual adjustment of our automatic guideline suggestion.

The mode Mix/Balance should be considered “Distance”. Designed to work correctly with Precedence. The idea is merely to set a Distance value in Precedence and then manually enter the same numerical value into the Mix parameter in the Breeze instance that follows it. Precedence supplies about half of the actual distance illusion, and Breeze 2 provides the other half.

Together they create an incredible sense of depth and allow you place instruments anywhere within the space that Breeze 2 creates: left to right, as well as front-to-back. The Precedence algorithm has been designed with this in mind. Both can be used independently of course, but true magic happens when used together.

We are attempting to establish communication between Precedence and Breeze 2 instances so that by merely changing position in Precedence, Breeze settings will be updated appropriately as well. The integration will take a little extra time and come in another free update later this year hopefully before the holiday season. At the moment, just manually set Breeze Mix to the same value as Precedence Distance. This will be available in future versions of B2 and Aether as well in one form or another as they become available. Precedence is an essential member of the family, and the link between it and our reverbs is compelling.

Chameleon Color GUI

The same color system available in Precedence is available in Breeze 2. All 150 factory supplied color preferences are also available. You can make a vast variety of custom GUI themes now, to suit your style and vibe!

Suspend Processing On Zero Input

Ultra low CPU usage is great, but there is one thing even better: zero CPU usage! Beginning with Precedence and Breeze 2.1, we have now introduced an intelligent suspend-on-silence feature in our products.

If the plug-ins are not receiving any input signal, they will automatically disable processing, and enter an approximately zero CPU usage state! For 2CAudio it is massive news for composers who use massive scoring templates and like to auto-load hundreds of instances. Maximum CPU usage will only be reached in such cases when all tracks in the project are active at the same time, which almost never happens in large sessions.

Sparse arrangements can save orders of magnitude in CPU-resources, which in turn leads to more creative freedom and fewer annoyances such as heat and fan noise generated by powerful computers in the studio. Furthermore, if playback is stopped for a coffee break, lunch break, or overnight, processing is automatically suspended, potentially saving you significant money on your electric bill. In other words, we automatically turn the lights off for you, helping to save the planet in the process. We think that is pretty cool.

In Breeze 2.1 some Alg Modes do not reach precisely zero CPU at the moment, as we achieve in Precedence, but we can turn off the most intensive part of the algorithm. And about half of them reach almost precisely zero. Note that we must wait longer to turn compelling off given that reverb adds decay and we don’t want to chop off the tails. How long we expect is a function of the current reverb time and other things.

New Filter Types

Some cool new filters for EQ and Damp: Tilt II Dual Shelf Bell See the 2.1 example presets.

Phase Inversion Button

In Breeze 2.0, our novel spatialization of the dry signal could sometimes result in the signal being more out of phase than in phase: i.e., having a negative correlation. It is a “super stereo” effect, which can be quite cool in some contexts such as use on synths etc., but it can also confuse instrument position within large mixes.

Thus we have taken a closer look at that, and have prevented it from happening by chance statistically speaking. All presets should now remain more in-phase, than out-of-phase, at least for wide frequency ranges. If you have an instrument that is playing a melody in a very narrow frequency range, such as a say a static sine wave, phase inversion is still possible in close frequency ranges, but a whole string section for example or even the performance of a single violin over the course of its performance will stay in phase on average.

It helps localization be more defined and specific which also helps Precedence work its magic. Some potential users mentioned they loved the sound of Breeze 2 in solo but occasionally found it challenging to out-of-phase into large mixes. The 2CAudio was likely the reason, and this topic should be much improved and is also essential for Precedence interaction.

If you wish to abuse anti-phase, super-stereo effects intentionally for special effects and synths etc, we now have a phase invert button that will allow you to do that. You can also use it to correct any problematic narrow-range instrument that manages to escape our statistical process. This button is similar to what has already been in B2.

Channel Swap Button

Channel Swap, reverses the input channels, making Right Feed Left and vice versa. That can create slap-delay type effects in the opposite channels when applied to signals that have been hard-panned or “hard positioned” (i.e. 90 degrees) via Precedence.

It confuses localization to some extent, and should probably be avoided in large orchestral mixes, but it can be nice in smaller contemporary projects. It can be nice with the Hyper-Plate by merely for example. The button is also similar to what has already been in B2.
