frekvens

Frekvens is a frequency shifter and delay effect. Unlike a pitch shifter all frequencies are shifted linearly and then fed back into itself using the stereo delay unit. The frequency shifting is achieved with single sideband modulation using a hilbert transform and an infinite impulse response filter for fast computations. Frekvens also comes with a high and low pass filter and a lfo for modulating the delay play head.

Cool app, ui has issues on iPhone
Automaton Adam

UI elements near corners seldom register taps and overlays can sometimes freeze up on iOS 11.

I have the bundle!

The controls are somewhat cryptic but once you know what they do (as the on-screen hints indicate) you will find these are very cool apps.

Party over here...

Ahh..freqvens - probably my favorite iOS effector. This thing can do so much to your sound or you can real it back and it will give your audio a nice little sizzle or warble that, every one’s saying just pleases the ear. I’m not going to tell you no collusion because if you offer some extreme parameters to this device STAND BACK or moreover SIT DOWN because if you close your eyes it sounds like an imperial probe is sexting with the black knight and WHAT THE HELL WOULD THEY BE SAYING TO EACH OTHER ?? Buy this app and find out.

Maybe the Best of All

I use and enjoy all of the apps from this developer, but this one is already shaping up to be my favorite

Stellar App / Stellar Results

How much fun can one have bending and blurring audio? Get frekvens and find out. This app is so smart and ready to play you'll feel like you've got a bouncy puppy which can make your audio roar (or purr or growl or hover like a ghost etc etc). The UI is minimal graphic genius and the magic going on under the hood can turn nearly Any sound source into potential gold. A delicate balance of control and chaos that somehow gets it just right: get it now and don't look back.

Very good effect

Good but...

This is great audio processor, bit it desparately needs inte-app audio.

Unique

I love Erik Sigth a.k.a. Humbletunes' apps. Imaginative, inexpensive, innovative and like nothing else on iOS. Buy them all.

Really dig this in my AB middle slot! The versatile ways it can both smooth a sound and fully mangle a rhythm track simply makes me get goose bumps with the audio results quite often. Been using it since it first arrived yet neglected writing a review. This developer makes great apps. I fully appreciate the GUI he chooses to employ because (not like this matters to anyone...) I think pretty graphics are cool but when I want to make music and sound, I like the idea that my device’s focus is that and not so much beveled, color gradient enhanced, 3D-looking synth replicas. It’s the sound I care about and Humble is a master.
