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.

Haaze 2 is a 16 band stereo widening tool that utilizes three different methods of controlling the stereo width and spatial positioning of an audio stream: • Haas – adds a small delay to the left or right audio channel, creating the perceived effect of the sound arriving from the side that’s reaching the ear first. • Pan – alters the gain level on either audio channel. All 16 bands can be panned separately, so this method is quite equal to the “split EQ” function often found on various well-rounded equalizers. • MS Stereo – controls the output stereo width on each band, from normal stereo signal to mono. There’s also a view for controlling the output gain of all bands separately. New features from version 2.0 and later: • New and more transparent crossover filters • Haas: Better control for each band • Split EQ is now called "PAN" and provides much more control • MS Stereo • Gain • Visualization • Brand new and more intuitive UI for a better work flow. • Several factory presets. Full documentation available inside the app or at https://klevgrand.se/downloads/haaze-docs/ Audio examples and more info at https://klevgrand.se/products/haaze Haaze 2 works both as a standalone app and as an AUv3 plugin.
