FabFilter Pro-R 2 is a top-quality reverb plug-in that helps create rich spaces in audio. It uses natural reverb algorithms, vintage reverb algorithms, and plate reverb algorithms to deliver a range of sounds with intuitive controls. The app is designed to blend well with your audio sources, making it easy to fit into any mix.

One standout feature is the Space control, which lets you switch between many room models effortlessly. It adjusts the decay time automatically, so you can focus on your sound without worrying about technical details. The Decay Rate EQ is another innovative element, allowing free adjustment of decay time over different frequencies, which gives users more creative freedom.

FabFilter Pro-R 2 includes a built-in Post EQ, enhancing its usability with high-quality factory presets that sound fantastic. It also filters microphone input in real-time, allowing you to hear the effects instantly. To use Pro-R 2 as a plug-in, you'll need an AUv3-compatible host app like Auria, AUM, or Cubasis. Once you have one of these apps, Pro-R 2 will appear alongside other Audio Unit extensions for effect plug-ins.

In the latest version of Pro-R 2, you’ll find new vintage and plate algorithms that recreate classic reverb sounds. The thickness control can thicken, compress, and saturate audio, while the auto gate feature is perfect for achieving that gated drum reverb sound. There’s also built-in ducking to ensure the reverb blends seamlessly with your source material. If you have specific reverb requirements, the import IR feature allows you to bring in an impulse response file in WAV or AIFF format and adjust the reverb and EQ bands accordingly. Surround support is available for hosts that support immersive audio.

The app has mid/side options for Post EQ bands, output level metering, and a redesigned preset browser, all aimed at simplifying your workflow. FabFilter Pro-R 2 features beautifully designed room models, ranging from small ambiences to large concert halls and majestic cathedrals. It is crafted to sit nicely in the mix without causing unwanted issues like coloration or phase problems.

You’ll enjoy a user-friendly Retina interface that includes a large interactive reverb display. The Space control allows for smooth changes in room model and decay time, helping you avoid clicks or unwanted artifacts while exploring over a dozen carefully designed room models. The Decay Rate control enables you to modify the overall decay time from as low as 25% to as high as 400% of the current setting.

The intelligent stereo width control gives you options from pure mono to true stereo and even beyond. You can use the distance control to adjust how close the sound source feels within the selected space. The character control changes from a clear, transparent decay to an engaging reverb filled with reflections and echoes, even creating a chorus-like effect if desired.

The predelay knob ranges from 0 to 500 milliseconds, and there's an option for tempo sync. The innovative six-band Decay Rate EQ offers Low/High Shelf, Bell, and Notch filters, providing extensive control over decay rates at various frequencies. Alongside this, the six-band Post EQ allows for fine-tuning the final reverb sound with options like Low/High Cut, Low/High Shelf, and Bell filters. Together, these features enable you to craft any style or character of reverb.

For those who love visual feedback, the real-time spectrum analyzer helps you see the decay time at different frequencies. The app comes with a curated collection of presets, allowing you to save, restore, and organize your own settings easily. Plus, you have undo/redo functionality and A/B comparison options to help you refine your sound.

Overall, FabFilter Pro-R 2 is not just a tool; it's a versatile companion that enhances creativity and brings joy to the audio production process.
