Audio Function Generator PRO

elegant and sophisticated 😎

I’d been using the basics but recently needed something pretty weird. The 48 customizable presets and the BPM modulation feature allowed me to achieve what I needed. A GREAT app. Thank you!

If you want more stars please explain how to get logarithmic sweeps and logarithmic scale for the frequency slider. A linear sweep is pretty useless in the audio world.

This app is a fantastic helper! Great interface and fast responses with technical questions.

This app makes it easy to play 528hz, 432hz, Solfeggio tones, white noise and other custom audio frequencies for healing and any other audio production, meditation or enjoyment purpose. Any creative audio professional should get ahold of this app, especially if you want to use non-standard tunings. I use it to match tones, tune songs, audio files and instruments by ear, play true binaural beats, match frequencies on my modular Synthesizer and more. It’s my go-to reference for 432hz, 528hz and Solfeggio tones for my music. Thanks for making this app! - DJ Soulfeggio

Awesome app to test and tune your set up or just to test the capabilities of your speakers. I like to use my finger to slide through the frequencies.

Screwy volume when using the iPhone side buttons. Jumps up and down by 6 or more, also displays wrong volume level (sometimes even shows “muted” when not). NEEDS to be increased and decreased by 1. Slider works fine but I very much dislike sliders especially when they’re that small. Other than that nice app with lots of features. Using on iPhone 12 Pro and iPad Pro 9.7, same issue on both. Please fix! Will change to 5⭐️ when this issue is fixed. Update: I wasn’t aware the volume button issue was an Apple limitation. Hats off to the developers for being so attentive to the end users. Outstanding app! Money well spent.

The details and options of controlling sound waves is more than you could ask for in a iOS app! It’s pure mathematics in your hand... and ears! Although I have many technical/scientific uses for it, I like to set up a deep-bass, oscillation, multiphase-waveform as I lay on a couch with a subwoofer underneath - a fully customizable back massage... the ultimate no-contact TENS device! Thank you to the developer for keeping it up all these years!

Tom Gruber’s other application Multitone Pro. All his applications are phenomenal though; especially the EE Toolkit! The only suggestions I have are to enable ping-pong sweeps in the Multitone windows and to allow sweeping of the noise/adding noise in the Multitone sweep (with a sweeping bandpass filter).

Awesome 👏🏻 Audio Function Generator!!!
