A convolution reverb takes a sample from a real-world space (called an impulse response or IR) and uses this to digitally simulate the reverberation of that space. "Only a convolution reverb can capture the ambience of a real space, or real hardware, and recreate it on a computer," explains Ableton sound designer Christian Kleine. "With a convolution reverb, you can easily access the reverb of many spaces, and still tweak them."
Convolution Reverb also includes a utility for creating your own reverb spaces. The IR Measurement Tool device facilitates the creation of personal IRs. Use it to get a perfect sample from your own hardware or just drag and drop an audio file into the Convolution Reverb device. You don't even need to stick to reverberant spaces. Experiment with a variety of sounds and explore new spaces.
Convolution Reverb is a method of digital reverb that uses a recording (called an impulse response) from a space. The convolution reverb then analyses it and uses it to recreate the reverb from that space.
A recording is taking of a short, sharp , loud sound (like starter pistol or loud clap) in the space, and the reverb tail is captured. Then this is loaded into the digital convolution reverb, which then reproduces the reverb. For example recording a loud snare in a church would allow the sound of the response.
On the left you have Decay and Size which is set to 100% by default. Which mean they reproduce the reverb of the space the IR was recorded in exactly. You can then boost or lower these settings to edit the decay and size of the original reverb settings to tweak it to taste.
The column on the right has Width, which can be used to reduce the stereo width of the reverb to taste. Underneath that is Gain, to boost the output volume of the reverb, as well as a Dry/Wet amount control.
In the center of the unit is the main screen which shows the Impulse Response in the IR tab. At the bottom of this tab is the Type and IR selectors to browse through the Impulse Responses. There are IRs recorded in real places from cathedrals and nuclear power plants, also some nice hall reverbs and smaller spaces. Aswell as this there are IRs that have been run through classic 80s and 90s hardware reverb units, including some really nice spring and plate verbs. There are plenty of really good spaces and reverbs here! Some are great for atmosphere, and others for drum processing etc.
The Mod tab adds a slightly LFO wobble to modulate the reverb. Two algorithms Mod I and Mod II. You can change frequency and amount.
The Damp tab gives you control over the reverbs dampening with a spectral EQ-like control over Freq, Decay and Q/resonance. 3 different points for each. This is a really nice sound design feature.
The Shape tab allows you add Fade In and Fade Out. It has some other controls too like Shape, Early (reflections), Length, and Cascade. It a great feature Reverse which outputs a reverse reverb effect.
These tabs, especially the Damp and Shape tabs are a really good sound design feature, especially for detailing reverb which can get muddy. This unit is great for sculpting reverb on a techno reverb rumble kick for example.
Convolution reverbs are reverb effects which use impulse responses (IRs) to simulate an acoustic space. These are the best freeware convolution reverb effects in VST plugin format for digital audio workstations on PC and Mac.
An impulse response captures the sound of an acoustic space or an artificially simulated space (when recorded from a hardware reverb unit, for example). Loading an impulse response in a convolution reverb effect will apply the reverb properties of the sampled acoustic space to the processed audio signal. This way, we can simulate recording an audio track in a natural environment (by using impulse responses of outdoor spaces) or mimic the sound of expensive hardware reverb effects.
The user interface is well designed, with the file browser on the right, waveform display on the top, the control parameters on the left, and the spectrum display on the bottom. The user can adjust the pre-delay time and the envelope of the loaded impulse response. The IR can also be time-stretched, which is a great feature to have in a convolution plugin. SIR1 has a fixed latency of 8960 samples and is optimized for low CPU consumption.
The plugin features a selection of impulse responses captured from legendary hardware reverb units such as the EMT 240, AKG BX 20, Lexicon PCM96, and the Bricasti M7. The presets can be customized using detailed envelope and tone control parameters. The user can adjust the pre-delay time, attack/release times, and trim the loaded impulse response. The plugin also features a 3-band tone control and a damping control for shaping the tone of the reverb tails.
Due to its relatively affordable price and well-designed user interface, Fog Convolver is our recommended commercial convolution reverb VST plugin. It comes with a huge library of impulse responses and features a slick user interface with plenty of customization options.
The convolution algorithm in JUCE is state of the art uniform partitioned convolution algorithm. That means that it is not really suited for IR with a size higher than 1 second, for which not uniform partitioned algorithms are mandatory and being used by every single reverb convolution plug-in.
If you still want to use JUCE for your convolution reverb, you might want to increase the buffer size of the algorithm processing block, and handle the additional latency by yourself. Or you might want to try another convolution library. Moreover, if you are doing your tests on Windows, the CPU load might decrease if you install Intel MKL and use it with the JUCE FFT class wrapper (on macOS vDSP is automatically being used).
In Reaverb, I think you need to enable the ZL and LL options to do a fair comparison, otherwise the algorithm is working with a high latency which is a very good way to reduce CPU consumption for a convolution algorithm.
I have tested that library, at that time I was wondering why would someone use a variable block size in a convolution library (now I know lol). But the coding style is quite horrible and it has a GPL license, so using it is not an option.
Shameless promotion:
I can offer a commercial license to my zero latency non-uniform multichannel multiplatform realtime convolution, already proven to work in a number of commercially available products.
Why does convolution spoil readPointer? I wanted to mix with a dry signal, took getReadPointer, and there is a wet convolution signal. I had to make a separate buffer and copy the dry signal into it before.
Reverb is an essential tool for audio engineers and producers. It gives the effect of a signal being heard in a sonic space. When a sound is produced in a given space, the soundwaves reflect off surfaces, creating echoes that result in the reverb effect. Editing software aims to replicate these spaces.
Not only is reverb used for adding a sense of space, but also for other creative effects. Having long decay times on a reverb tail can be used to create drone sounds, or if you want your sound to open up, adding reverb will do just that.
Within the audio plug-in, the signal goes through a series of delay lines that create quick and close-space delays. Algorithms control and modulate these delay timings into different patterns which will denote the characteristics of various types of reverb. This is to create the early reflections.
Algorithmic reverbs then aim to create late reflections, achieved through feedback loops. It takes those early reflections and feeds them back through the algorithm. This feedback can be adjusted through decay time, which are parameters found on every reverb plug-in.
While algorithmic reverb is based on algorithms, convolution reverb utilizes impulse responses, which are recordings from real-life spaces. You can send your audio into these spaces for a hyper-realistic reverb effect.
Convolution reverb is particularly favored for tuned signal sources, as the reverb harmonically links to the input signal, creating a more convincing effect. However, it can also be effectively used for other sound effects.
An efficient way to use convolution reverb is as a return track effect. This approach allows multiple tracks to be affected by a single convolution reverb, reducing CPU strain and creating a more convincing sense of space.
Convolution reverb is also better used for musical instruments. If you are recording a string quartet or any solo instrument, convolution will yield a more realistic space for your instrument. This can also be applied to other sound effects you want placed in a realistic space.
Algorithmic reverb has preferable uses in music production where the reverb is used to enrich your tracks. For those looking to take tracks away from a realistic space and to smear the sound within an expansive space for more supernatural effects, algorithmic reverb is the one to use.
Typically, algorithmic reverbs allow more control over the components, enabling you to be more creative with the type of space you want. Convolution reverbs are more set in stone from the impulse responses. However, some plug-ins allow some control, such as pre-delay and EQ. Parameters like decay time are usually fixed in convolutions, giving it its spatial identity.
Ableton Live also has an easy-to-use stock reverb plug-in that has a wide range of parameters to control for shaping sound. This reverb also has a freeze button, which freezes the reverb tail, which is perfect for creating drones!
