Traditional EQs influence the spectrum of the whole stereo field simultaneously. L/R or Mid-Side-EQs allow you to treat the two channels or the mid and the side signal simultaneously. DirectionalEQ takes this concept one big step further: now you can equalize all directions in the stereo field independently! With five bands, each of them providing state-of-the-art filter types (including 64 bit processing and 2x oversampling) plus the unique ability to specify the direction in which the channel is operational. So you need more bass at 2 o’clock, less midrange at 11 o’clock and a bit more treble from the left? No problem at all, that’s exactly what this EQ has been made for! This app is intended to work as an Audio Unit or Inter App Audio plugin within a compatible host app like Garageband, Cubasis or Auria.

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.
