Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.

How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

Review momentum
20/100
faster than 0% of Music apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About FAC Alteza
• Exospheric stereo reverb with ultra low latency pitch shifting
• Amazingly lush, dreamy and beautiful
• Shimmer kind effect, harmonizer
• Unique feedback processor and fine tuning of the All-Pass delays
• High-pass filter and stereo width input controls, separate Dry/Wet outputs
• Sidechain input to duck the reverb
• Multiple outputs, extra output bus to route the feedback signal to your own fxs
• Advanced Responsive Design, portrait and landscape views
• iOS Audio Unit V3 - Universal (iPad/iPhone)
Designed for ethereal lush sound textures and dreamy space reflection, FAC Alteza is the perfect solution to bring your instruments to heaven in no time. Thanks to a powerful feedback section containing, inter alia, two pitch shifters, the unit is able to deliver the very typical "Shimmer" sound kind effect very much prized by musicians that are making ambient music, or any kind of music that needs to be carried by a fabulous angelic evolving choir section.
FAC Alteza is definitely not "another shimmer reverb..." effect because it comes with additional parameters that make it very versatile. A particular attention to each part of the signal path was necessary to reach this level of high-end quality.
Here some features that make FAC Alteza an outstanding unit:
• the input signal is not monoized by default, a knob allows to control the width of the input stereo image before reaching the reverb
• the topology of the effect, based upon a series of All-Pass delays, allows to control the intrasec characteristics of the reverberation
• the number of All-Pass delays per stage and the echo density are alterable in the main section and in the feedback section
• two ultra low latency pitch shifters deliver progressive pitch-shifting of the reverberation tail or the input signal
• the feedback section contains a blend knob to control how much of the original signal is mixed with the feedback reverb
• the wet signal can be ducked by an external signal provided by the host
- AuV3 and Standalone App
- To use the sidechain and/or to output the additional feedback signal, you need a host able to provide to the AuV3 an input bus and an additional output bus.
