Blamsoft tells us that their new 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. Here's their own description:

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  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 Audio Unit Extension that works inside host apps. Just open up your favorite host that supports Audio Units and add it as an effect. 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.

The sixteen filter modes available are:

• 1, 2, 3, and 4 Pole Lowpass
• 1, 2, 3, and 4, Pole Highpass
• 2 and 4 Pole Bandpass
• 2 Pole Notch
• 3 Pole Phase
• 2 Pole Highpass + 1 Pole Lowpass
• 3 Pole Highpass + 1 Pole Lowpass
• 2 Pole Notch + 1 Pole Lowpass
