Spectral Eye

I am writing this review because they made this app free to use and thus free to enjoy. Its like a part of humanity in us that just wants to share the joy like a celebration of life. Thank you, I love science and sound is amazing, not prticularly for hearing it but that sound is ripples of pressure through the air, higher frequencies make closer ripples, low base makes long ripples, louder sounds increase the pressure, quiter is less pressure. So you can scientifically create the pressure and size within the air, but one really cool thing you can do with these pressure ripples is reflect them back to their source, and if you get the distance between the source and the reflection surface to be a distance that is a multiple of the width of a ripple then you get what looks like sound standing still, you would need some fog and light to see it, but its called a standing wave and you could place little nurf pelletts in the standing wave and the standing wave will hold them in place, if your reflecting vertically else they will fall but vertical floating balls is what many people like to dramatize the effect by calling it levitation and indeed is entertaining. Its not the toy aspect that is interesting, its the contemplation of what you have actuallly done that would seem impossible, a strip of pressurized air that has no walls yet does not leak. Imagination can lead us to what we could do with that. I hope you enjoyed my small add-on knowlege. Thank you Developers!

I wish this, exactly this, was included in every synth. Because trying to recreate a specific sound using pretty much any synth is soooo much more difficult without a spectrum analizer such as this. But it's fairly rare to find any on the app store that actually show the notes, and the octives, in such an easy layout such as this. But I mainly came here to say, that it's 2020. Audiobus 3 is here. Auv3 is here too. Add some ios versions later, and sadly, this app kind of only works with the mic now. If you launch it with AUM... Well... It doesn't launch at all. AUM gives an error and suggests you try again. And if you launch it with Audiobus 3, it actually launches, but it receives no audio from Audiobus... It just continue to receive mic, and Audiobus thinks this app is "asleep". So I'm still using it, with just the mic. I play back audio through my phones speaker, lol. Not ideal, but it's still the best, and it's free. This app needs to be updated, but maybe the dev doesn't have time. Any chance it could be released as open source? Then maybe someone else would be willing to update it, to keep it functioning fully?

Awesome, nothing else comes close, and yet it's free. This is the go to app for tuning your whole guitar in one strum, examining your chords, and practicing polytone singing. Because you can see the weight of each note, you can get a good idea why your sound is going wrong in spite of supposedly being in tune. It's additional features are cool and useful too. If you work in microtonal instruments like slide guitar or need to figure out what's really going on when multiple notes are playing, but in terms of music theory, not just frequency numbers, and would like to visualize it, this is the app to use.
