Free plugin alert, and it’s one that everyone can benefit from. Yes, it’s also for Linux users, too.

Xunil-cloud has released CloudReverb, a free reverb plugin for macOS, Linux, and Windows.

Xunil-cloud CloudReverb

CloudReverb is a new algorithmic reverb that is based on the CloudSeed VST by Valdemar Erlingsson. It is an old open-source plugin for Windows (7 years old) that has not been updated for many years, but it has a pretty extensive feature set.

Xunil-cloud has rewritten the code for CloudReverb with JUCE, so it can also run on Linux, macOS, and Windows.

CloudReverb has various section that allows you to modify the sound. It starts with the input section and the mix knob that controls the amount of mixing between the two input channels. Next to this is a pre-delay that adds a delay to the signal before it enters the reverberation process

Then, after the pre-delay, there are low-cut and high-cut filters with high-pass and low-pass options, giving you high-pass and low-pass filters to mangle the signals before the actual reverb.

The next step is an early reflection/diffusion section that has two components: a multi-tap delay (500ms delay up to 50 taps) and a series of Schroeder allpass filters to thicken up the reflections.

Deeper Reverb Crafting

From here, it goes into a late reverberation block based on up to 12 parallel delay lines. Each delay line has a feedback control; the feedback signal is processed through a high- and low-shelf filter, as well as a first-order low-pass filter.

There is also a Schroeder allpass filter block that is placed in the feedback chain. Nice, you can also change the order in which the delay and the allpass filter are processed, by using the Late Stage Tap (30) control.

Further, a mixer melts all the elements (dry/wet mix, pre-delay, early, and late reflections) into a reverb. There is also a cross seed parameter that controls how the random values for the left and right channels are mixed.

Xunil-cloud CloudReverb ships with various presets that showcase the capabilities of the reverb engine.

Xuntil-cloud CloudReverb is available now as a free download. It runs as a VST3, AU, and LV2 plugin on macOS (native Apple Silicon + Intel), Linux, and Windows.

The code is open-source. According to the developer, it only tested the Linux and Windows versions not the macOS.
