A cat voice generator that calculates sound wave made by the vibration of cat vocal cords modified by the resonance of the vocal tract in real time. (not playbacks of recorded audio) It can produce various cat voices (like human talking or whispering). At a glance, this app may look like a musical instrument with a keyboard. But it is not for the purpose of playing music. However, you can play music or beautiful chorus composed of cat voices. Moving your finger horizontally on the keyboard, cat voice pitch rises and falls. And moving your finger vertically, cat voice pronunciation changes. Touch the DEMO 1 button on top-left on the screen, it teaches how to make variation. Slide the metronome on the left and watch the cat eyes flash. Toggle through the options of voice tone on the right side of the screen. ## Key features - Real-time sound wave generation - Simulates cat vocal cords and tract - Produces various cat voice types - Musical instrument-like interface - Pitch and pronunciation control - Demo mode for variations - Voice tone options ## Recent user reviews (10 of 10) All indexed reviews: https://appshunter.io/ios/app/feline-synth/id659764677/reviews.md ### 1/5 — Nice idea in theory but… *2023-01-24, version 7* There is no sound. ### 2/5 — So that happened *2019-09-25, version 6* I forgot I had already downloaded this on my phone. This is so dumb. I was hoping it would be cute and fun, but it’s neither. It’s just kind of weird. MeowSynth VST by Knobster was better. ### 5/5 — Toe Toot! *2019-08-10, version 6* Tis is ta tootest toy I ever twied! ### 5/5 — Best! *2017-05-15, version 6* This is the best and most fun app evah!!!! I like making the kitty sound like grindcore ### 5/5 — Divine *2016-02-09, version 1.2* Today I learned why I have an iOS device. ### 5/5 — This is the greatest thing that has ever happened *2015-12-31, version 1.2* Seriously. Ever. ### 5/5 — best ever! *2015-08-08, version 1.2* this is the epoch egress to oblivion dance to the future ~ ### 5/5 — Kudos to the great maker *2015-07-02, version 1.2* This was certainly...interesting :P ### 5/5 — Incredible *2013-10-18, version 1.2* It changed my life!!!! ### 1/5 — iPhone 5 - only background visible *2013-07-10, version 1.1* Yes, it's a quirky concept—but I wanted to give it a try, since I love playing with odd music apps. But when I opened it on my iPhone 5, all I saw was the canvas image of the background. Moving my finger around on the screen made noise occasionally, but this app is FAR from usable as is. No idea how this got past the App Store review. Please fix—I actually do want to noodle around with this. ## Frequently asked questions about Feline Synth ねこシンセサイザー ### Does Feline Synth have ads?
