F-16 Filter is a flexible multi-mode filter with frequency response display. It features sixteen modes, frequency and resonance controls, saturation for analog-style soft clipping, and wet/dry mix. The 4 pole lowpass mode provides the frequency response of classic the Moog ladder filter. The other modes provide all of the choices available in the famous Oberheim Matrix 12 and Xpander synthesizers. At the heart of F-16 is a Zero Delay Feedback algorithm, the latest in DSP filtering technology. F-16 Filter gives you a wide variety of filtering options with pristine fidelity.

F-16 Filter is an AUv3 that works inside host apps. Just open up your favorite host that supports AUv3 and add it as an effect. Compatible with GarageBand, Cubasis, Auria, BeatMaker, AudioBus, AUM, Modstep, and more.

Blamsoft brings their experience creating top notch plug-ins for the desktop to iOS. The same filter modes are found in the popular Rack Extension for Propellerhead Reason. You get a desktop quality plug-in at an iOS friendly price.

In addition to controlling the filter through the knobs and sliders, you can use the frequency response display to control cutoff frequency and resonance simultaneously.

1, 2, 3, and 4 Pole Lowpass
1, 2, 3, and 4, Pole Highpass

Right on the money

Not only is this a great filter for less than a cup of coffee and a donut, but it's ahead of many apps 10 times the price by supporting Audio Units on the Ipad, which imo, is just as if not more important than Audiobus or Inter App Audio. I have all the apps made by this developer for IOS and I'm looking forward to more, please continue bringing us more audio units and keep up the great work!

I thought I purchased a filter

Not much to say. I thought I purchased a filter, but it looks like all I actually received was the manual.

Developer Response ,

The app in­stalls an AUv3 plug­in that is avail­able in host DAW apps. If you are not fa­mil­iar with AUv3, I sug­gest start­ing with Garage­Band. You can add the plug­in as an ef­fect to a Garage­Band in­stru­ment track. In Garage­Band, tap "Plug-ins & EQ". Then tap "Edit". Tap a green plus sign but­ton to add an ef­fect in an emp­ty slot. Then you will see "Au­dio Unit Ex­ten­sions". Choose F-16 Filter from the list.
