[Update] __ A great App just got a little better ! The History feature is icing on the cake. . . I tried the free version, and within minutes purchased PRO … This App is a superb piece of work and works beautifully on my ageing 9.7” iPad Pro. Many thanks to the developer for his craftsmanship!

Jól használható app hangrendszerek autóhifi beállításakor, ellenőrzésekor, teremakusztika mérésére. Useful app! Would be nice to store settings as presets. Playable charts. Thanks!

We can use Function Generator Pro with Function Generator Free to play 2 frequencies at the same time with BPM. Best for Binaural Beats. We can Create the Sound we Want. MOST VALUABLE APP OF THE APPLE STORE PLUS CHEAP COST ! A MUST GET !!

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

Schade: Bei der pro-Version habe ich ein Tool, unabdingbar zum Einmessen von Lautsprechersystemen, das Terzrauschen, schmerzlich vermisst. Ist ja alles schick und intuitiv zu bedienen, aber so ist die App für mich nutzlos. Haben Sie eine Empfehlung?

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!
