A high-quality audio Signal Generator for the iPhone. Now you can have a professional grade signal generator for your iPhone. Create sine waves, square waves, white noise, and pink noise. The signal generator can help you generate sine, square, triangle, sawtooth, white noise, pink noise signals and generate sine two-channel phase difference waves. You can use the signal generator to test your audio frequency response system, system noise scanning, headset burning machine and other scenarios. Test your hearing can hear how low the frequency of sound. Able to apply and experiment with test scenarios. ## Key features - Sine wave generation - Square wave generation - White noise generation - Pink noise generation - Two-channel phase difference waves - Audio frequency response testing - Hearing test capabilities ## Chart rankings - #198 in Top Paid · Utilities (US App Store) ## Recent user reviews (7 of 7) All indexed reviews: https://appshunter.io/ios/app/signal-generator-wave/id1309709776/reviews.md ### 5/5 — Excellent tool! *2023-11-02* Thank you very much! ### 5/5 — Great! *2023-06-22* Nice little function generator, works well and I now know I can’t hear anything over 13kHz. The joys of getting old lol ### 5/5 — Works great *2022-06-16* Easy but powerful app. ### 4/5 — Nice easy to use app. *2020-09-19* Easy to use app. Would give 5 stars if it would allow to use airplay to transfer the sound to my car stereo for testing. Seems to be only to use the internal IPhone speaker. ### 5/5 — Easy Layout - Replaced Old Apps *2020-01-23* I’m an Audio Engineer that services commercial installed AV systems. I use apps like this on the daily for testing, but haven’t found one that is ad free, no frills, and does what I need without paying an arm and a leg for, so I’ve been using old (developer gave up on) apps... until now. Thanks for making this app! One suggestion I have is somehow making adjustable variables when using “random”. would love to narrow down and set a group of frequencies and at an adjustable rate of time, but just an idea. ### 3/5 — Geht *2019-07-03* Macht was sie soll, aber leider läuft sie nicht im Hintergrund :( Geht aus sobald man den Bildschirm abschaltet.... ### 5/5 — Great *2018-09-26* Very well layed out ## Frequently asked questions about Signal Generator ### What types of signals can Signal Generator - Wave produce?
