User Reviews for Audio Function Generator

Multiple tone adding is fantastic

When doing sine wave addition with amplifiers. This app provides the signal and the ability to see an ideal sine addition. Then I can measure the actual frequency wave addition in an external scope and compare the two. No other frequency generators that I know of allowed me to do this. With DSP I can send in a combination of 5 sine,cos,square,etc. waves then watch what my DSP. algorithms , say run a Fourier (FFT) I wrote or came from the OEM and check how good it is. Amazing tool from my iPad.

Very handy app

This is a good looking app aesthetically and delivers solid, intuitive controls. All the functions are easy to use and provide more tools than the average person will use. That means it won’t run out of functionality as you learn to use it for various things. I love the inclusion of various types of noise which I can use to burn in speakers or relax and fall asleep to. The sweeps are great for testing and recording impulse responses and impedance curves. So many more uses that I won’t take up your time and will just say that it would be hard to find a better all-in-one tone and function generator out there. And it’s super affordable for even the tightest budgets. 5/5 stars!

Has Everything

Not only do I find this app very beautifully designed from a graphic viewpoint it’s also very functional and easy to use. The features are basically what everybody needs for testing and calibrating audio equipment. It’s a generator not an analyzer so you need to keep that in mind. It doesn’t give you THD distortion measurement or anything like that but it is a great source generator. I found the pro version well worth the small price. Congratulations to the author of this program - very nice job!

Useful

I have a foreign low frequency (around 60-70Hz) messing up with my ears in my home and I wanted something to easily match the exact frequency I hear.Being able to fine tune the frequency in the free version it allowed me to precisely match the noise that is troubling me (but I still can't identify the source, though)This app is perfect, and the plethora of options in the free version made me review it without being asked to.

ios 5 was the best, Jan 06, 2018

This is THE app you are looking for!

I tried several tone generators and any trap of them allowed for actually selecting a specific tone. This app is by far the best one available. AnD that is what I think of the free version, which did all I wanted and more. The only reason I purchased the pro version was to support the developer for doing such great work. I wish more developers made apps this useful. Thank you very much for a great app!

Great Functionality

This app works as described. The UI makes navigating all of the options simple & fun. Kudos to the developer.The developer was also very prompt to respond when I contacted him for what I thought was a hidden charge. Turned out it was just a coincidence with the timing on my notifications. He handled the situation in a professional & respectable manner. So I give an additional A+ rating for customer service as well 👌🏼

Excellent Frequency And Noise Generator

I have been working in professional audio for 30 years. I tune rooms and speaker placement, set up EQs, tune subwoofer boxes, find panel resonances, etc. This handy app has all the features I could ever need, they are really usable, and they are geared toward the pro audio user. I tried 3 other frequency generator apps and this is superior by far. Free version is fine, but for $1.99 just go full. Thanks!

Does just about everything I need

I love this app. I've been studying and using frequencies for over 10 years now. I finally found an app that not only let's me go beyond whole number to decimals, but also let's me type in the exact frequency I want to run. No inaccurate sliders to fiddle with here. I use it regularly. I love the new sets feature.One thing I would like to see added is the ability to name the frequencies. I use different frequencies for different purposes. It would be nice to name Schumann Earth freq instead of having to memorize Earth is 7.83hz.

Best tool for an unusual problem.

Something was rattling in my car when playing music through my stereo. Problem was it would only rattle on certain bass notes and no song would create the rattle long enough for me to find it. It had driven me nuts for months!I picked up a cassette adapter to pipe my iPhone audio into my car stereo. Then I purchased this awesome App and immediately pulled up the Musical Note menu. Starting at the bottom, I began stepping up the note scale until BAM! There it was! I was able to reproduce the rattle. You won’t believe what I found. My spare garage door opener was vibrating inside my plastic glove box every time a bass guitar hit that note. From that moment, this Audio Function Generator from Thomas Gruber became worth 100 times what i paid for it. Thank You Tom! You rescued my driving sanity.

helps with tinnitus?

I’ve been testing a new idea to reduce tinnitus, ie to listen to the pitch that matches the pitch i hear due to tinnitus. this app has easy to use features and good sound quality. i just wish it would run in the background so i can multitask while doing this therapy. i’ll let you know how well it works to reduce tinnitus. (the idea is the brain creates ringing in the ears to compensate for frequencies compromised due to damage to certain parts of the cochlea. if the auditory nerve can be stimulated at these frequencies, so the theory goes, maybe the brain will stop simulating them)

Description

This is the highly recommended and praised Function Generator App - an amazingly great and powerful tone generator. Enriched with a vast amount of features yet it is extremely intuitive and designed for simplicity. Get to know this great App now!

It is very well maintained and has received considerable upgrades over the past years. So, … what can you do with this App? • PLAY TEST TONES Sine, Rectangular, Triangular and Sawtooth. • PLAY FREQUENCY SWEEP TEST TONES in both directions (minimum to maximum frequency and maximum to minimum frequency). • PLAY VOLUME SWEEPS (from minimum to maximum volume). • Try the SWEEP REPEAT / WOBBLE function. • Try the MUSIC TONES PLAYBACK. • Experiment with the huge FINE TUNE SELECTON, PRESETS SELECTION! • Or create your own CUSTOM PRESETS! • And SAVE an endless amount of CONFIGURATIONS (Frequency, Sweep, Noise) for later quick access and direct playback function. • Even play back different kinds of NOISE – White, Pink, Violet, Grey, Brown, Blue is also supported. The Function Generator is AMAZINGLY INTUITIVE and SIMPLE! AND THESE ARE THE ADVANCED SETTINGS/FEATURES (upgrade to PRO required): => Extending The Frequency Range => Extending The Sweep Times => Changing Min/Max Slider Frequency Ranges => Changing Max Sweep Time Slider Range => Changing Signal Amplitude => Enabling Of The Sweep Repeat / Wobble Function => Frequency Slider Setting to Linear or Logarithmic => Left/Right Channel Individual Selection => Permanently Saving Custom Presets => Saving Of Endless Number Of Audio Configurations => Phase Out Setting (custom phase shift of the generated signal) => BPM (Beats per Minute) Feature => Dual Function Generator => MultiTone Generator (playback of up to eight individual tones) => Background Theme Selection (Light/Dark) Check out the new Tutorial page: www.ee-toolkit.com/audio-function-generator
