About

ADverb2

This app emulates a vintage digital plate reverb unit from the 80s, offering a range of reverb effects from short and rich to long and ambient. It functions as a standalone effect, with Inter-App Audio, or as an AUv3 plugin for music production hosts.

Highlights
  • Vintage digital plate reverb emulation
  • Adjustable pre-delay, time, and size
  • Extensive filtering for reverb tail shaping
  • Logical vintage-style user interface
  • Cross-platform preset manager
  • Low CPU load optimized algorithm

ADverb2 is our love letter to the golden age of studio reverb: a small handful of controls, a big friendly panel, and a sound that flatters everything you run through it. Version 2.3 grows it from one algorithm into three. PLATE is the original ADverb algorithm, a classic digital plate with the fast build-up and silky decay that made these boxes famous. It remains untouched, and your old presets load exactly as before. AMBIENCE is a modern, airy space. It adds air and dimension around a source without an obvious tail at short settings, and blooms into a long, weightless wash when you push the time out. Time-varying early energy keeps it from ever sounding static. HALL is a large concert space, exceptionally smooth and very wide, with slow internal motion that keeps long decays lush instead of metallic. All three algorithms share the same simple control set: Pre-Delay, Reverb Time, Size, low and high Contour switches, Rolloff, and Diffusion, plus input level and output mix. The Input Mute and Reverb Stop kill switches let you perform with the reverb, choking the send or the tail on the beat. Mix Lock keeps your wet/dry setting pinned while you audition presets, ideal when ADverb2 sits on a send. Version 2.3 also brings our system-wide preset browser with folders and favorites, a hundred factory presets covering everything from drum plates to nine-second ambient washes, preset stepping right from the main panel, and presets that show up in your host's own preset menu. ADverb2 is an AUv3 Audio Unit and runs in any AUv3 host, including GarageBand and Logic Pro. The interface is fully resizable and scales to fit your device. No accounts, no ads, no in-app purchases.

AltiSpace is a convolution reverb app with advanced controls that provides realistic sounding natural acoustic space or the most famous reverb devices for any track or mix. A convolution reverb takes a captured sample (called an impulse response) from a real-world space or hardware and uses this to digitally simulate the reverberation of that space or device down to the last detail and nuance. Because it is sampled, not synthesized, convolution reverb is known for its stunning realism, and it is widely considered to be the best type of reverb. However, unlike the more common algorithmic reverbs, convolution reverbs usually does not have much control over the reverberation process. But AltiSpace, in addition to the ability to load your own impulse response files and a built-in library of real reverb device presets, has advanced settings such as EQ, gate, ducking, modulation and more. You can change the original impulse response parameters to something completely new and then save it as a new preset. This app has an easy-to-use user interface, where all the main controls are located on the single screen, and it is ready to use right out of the box, even without additional settings. And at the same time, you can easily change the parameters of the impulse responses from the built-in library to create your own sound. App features: Ability to import your own impulse response files. A large built-in library of presets from the most famous hardware reverbs. Convenient preset manager with the ability to group and search presets. Presets can be marked as favorites for display in the favorites group. Supports MIDI controllers (also Bluetooth) with learn or manually assign mode. Reverb can work with a stereo or mono input and convert it to stereo. Add dynamic noise before reverb for a more natural sound. The gate allows you to turn on the reverb when the threshold is exceeded. The ducking allows you to turn off the reverb when the threshold is exceeded. Sets the minimum reverb level for Gate and Ducking modes. Equalizer with high and low cut filters in chain before or after reverb. Changing the time (length) of the current impulse response. Possibility to set a fade out point for a smooth end of the impulse response. Sets the pre-delay time of the signal before reverb. Experimental feature to change the pitch of the impulse response. Amplifying early or late reflections. Adjusts the stereo image before the reverb. Haas effect for adding stereo space to a mono signal. Sets the depth and frequency of modulation the signal before reverb. Mixing dry / wet signal and adjusting the output level. Four-channel mode for better stereo ambience. Input and output level meters. Indicators of possible input clipping for standalone. Prevents any output clipping for standalone. Built-in full description of all controls.
