Numerical Audio has released RF-1, an Algorithmic Reverb for iOS. It comes with a number of unique reverb algorithms including Tremolo, Ensemble and VintageVerb and integrates with everything from AudioUnit Hosts over Audiobus to Inter-App Audio, Guitar- and USB Interfaces.

A spokesperson told us, "RF-1 is a collection of algorithmic reverbs capable of creating a variety of effects ranging from small rooms to huge, heavily modulated spaces and everything in between. It comes packed with multiple reverb algorithms, a solid standalone application, carefully tuned factory presets and a plethora of tweak-able controls."

Features:
* 5 unique reverb programs (see below)
* Continuously variable size
* Variable pre-delay
* Diffusion control
* Damping control
* Width control
* High- and Low shelves (+/- 6db pre effect)
* Mod section with depth and speed controls (Sine LFO 0.01hz to 5.0hz)

Programs:
1. Hall
Clean and bright sounding space with subtile modulation and gradually building density.

2. Plate
Dark, highly diffused sound with high initial echo density and dark modulation.

3. EnsembleVerb
Capable of huge, wide spaces with deep modulation.

4. TremoloVerb
Large, bright and always moving with amplitude modulation at the output.

5. VintageVerb
Dark, noisy and wonderfull sounding reverb modeled after the first digital reverbs from the late 70s. (10khz bandwidth / 12bit processing)

Connectivity:
* AudioUnitV3 Effect
* Inter-App Audio Effect
* Audiobus (Filter)
* Ableton Link
* USB Audio Interface (Standalone)
