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. - frequency shifter - high, low pass filter - stereo delay - core midi cc input - audiobus - inter app audio - audio unit extension - save, load ## frekvens Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/Purple123/v4/f5/f4/84/f5f484c9-bf3b-21ba-2c18-9bc81cd1a41b/mzl.rbnmwalw.png/640x960.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/Purple113/v4/1c/5b/d9/1c5bd9b2-7f37-9bb8-8b22-61318718ec3d/mzl.ikhuvxzp.png/640x960.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/Purple113/v4/e1/38/6a/e1386a52-6e56-119d-4ab7-0421fc680f88/mzl.zadyoith.png/640x960.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/Purple113/v4/b5/d8/91/b5d89140-264f-5e84-69b4-d326b2ace392/mzl.zlwhsadt.png/640x960.png) ## frekvens Rating Breakdown in United States - 5 stars: 18 (90%) - 4 stars: 1 (5%) - 3 stars: 0 (0%) - 2 stars: 1 (5%) - 1 stars: 0 (0%) ## frekvens Reviews in United States ### ***** "Inexpensive but not cheap" Put off getting this dev’s apps because they were inexpensive & expected them to cheap quality. Don’t waste time like I did. Get this app, or all of his apps. Read the reviews and trust the experiences. FREAK & NILS are 2 mandatory iOS audio production apps, regardless of genre of style; there is more use for what these do then what is described by the dev or what you should reasonably expect. It’s apps like these, priced to keep you creating competitively, that help the iOS platform offer equitable opportunities for everyone to have the tools to produce great music without worrying about your budget. -- Tenente, 2019-10-13 ### ***** "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. -- Mo Freeapps, 2018-11-19 ### ***** "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. -- anickt, 2018-11-06 ### **--- "Cool app, ui has issues on iPhone" UI elements near corners seldom register taps and overlays can sometimes freeze up on iOS 11. -- Automaton Adam, 2018-11-06 ### ***-- "Good but..." This is great audio processor, bit it desparately needs inte-app audio. -- hmosc, 2016-07-12 ### ****- "Very good effect" minimal, efficient, creative -- qwesterish, 2016-02-25 ### ***** "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. -- NoUserErrorHere!, 2016-02-23 ### ***** "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 -- Ben Efitofadoubt, 2016-02-22 [View all frekvens reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Apps Similar to frekvens -
