Spectral Eye

Easy and useful!

Fun to use and interesting to see the relationship between harmonics and primary tones. Check this one out.

Simplicity and excellence! Thx for creating this!!

I have found this app incredibly useful over the years; it’s gone with me on many adventures into the woods, as I figure out and fine tune my skills and experiment on various flutes. I use it to tune my instruments. I’ve discovered all kinds of neat relationships in the structures of sound. It’s helped me to fine tune and understand my voice. If there was a device that only had this app on it, and it was unavailable on the App Store, I would buy it. Dear developer, please don’t let this app die. 🙏❤️🤙

So, right off, this is almost the best guitar tuner I’ve used. If it would show the octave number of a note that would be very useful. Not strictly necessary assuming the strings aren’t totally out of tune, but it would be handy for full restringing. I get that the red dot at the bottom lets you adjust the number of components of the output as you slide it left and right, but moving it up and down does something to the volume I think, but only got the current note. Not sure this feature adds much.

Just try it

I likewatching the rings go round n round. Up the scales and down tothe ground. Ill definitely be checking out more of your apps!

This is a really neat way to interact with sound and music. It took a little bit, and a look at the info pane, to “get it,” but now that I do, this is proving to be a fantastic tool with sound design. Especially when aiming for complex synth sounds intending to suggest, but not state, different timbres to hint at, say a trumpet, but not to BE a trumpet. And in fact can help super nerds actually veer away from specific instrument “sounds,” by allowing them/us to see which harmonics to avoid. To say nothing about how it can help tune a drum set or drum machine. Truly a stellar bit of kit for anyone into sound for the sake of sound. This means musicians, physicists, sound designers, and anyone who wants to understand what makes THAT wobble, that drives them/us good-mad, better than the other wobble that just annoys them/us or makes us bad-mad. I’d love to see a graphics update, but for free I’m not even remotely complaining. I also ask that you make a way that people who DO want to throw resources at you be given at least some way to do so. Not necessarily with a purchase. It probably wouldn’t be employed a lot, so it would be imprudent to create a specific commercial account, but a simple means of sending a couple bucks here and there would help you see that people DO appreciate developers, and that we want you to keep developing. Some of us also get how evil certain... let’s call them “business arrangements,” can be. How many times can a dollar be taxed before the one being taxed has to pay more than the dollar earned? [rhetorical] Developers: thanks for the stellar tool, and for making it free, AND free of ads! I’ve actually been just quitting anything that ads AT me anymore, and the ads that open something?!? Bad-mad for sure! I’ve also avoided “in app purchase,” apps for a long, long time. At least since the first few burned me. I find both approaches to be dishonest. DRM is another nightmare too vast a topic to get into. The ultra short version is that spending resources (time, money, creativity, at least) on inconveniencing the people who actually support the product and/or developer takes resources from making an app or product, or service, or support, or anything that can take something from good to OMG TAKE MY MONEY. I want apps that inspire OMG TMM, and these days products have to overcome product abandonment burns too. Sorry this is so long, I don’t get out much.

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?

I’m enjoying it.
