FrequenSee - Spectrum Analyzer

I put some time into testing a bunch of these audio frequency and decibel apps using 4 different devices and none were able to do anything even close to what real spectrum analyzer was showing! Each device showed a completely incorrect reading. I couldn't even get any apps to match any other apps readings on the same device with them both running at the same time with pink noise sent from real RTA. Incredibly useless, use this to tune a stereo and you'll be wondering what happened to it.

Clean and Simple. Only way the app could be better would be to add a decibel meter, or make it splitscreen compatible so i could use a sound meter app in the other screen.

I actually tested the accuracy of this in my studio using a signal generator and it was insanely on point. I can imagine tons of ways to use this in the future.

I love this app. Would particularly love a way to analyze from an external input (line in or external mic).

Tottally awesome :-) Accurate and precise. Fun too!

Not configurable, no method of saving traces, inaccurate.

Absolutely correct it responds to music 🎶 tnk you however I want different kinds of colors while it is working

need a paid ad free option and a few adjustment settings

I tuned a room with it and won some awards for the venue. Love it

Very simple and easy to use. Thank you!

Quite basic, but not bad. Does what it says

I've test it, can't heard past 10k. Not disappoint but ok

You never know when you want to know something.

I paid for this app back in the day and now there is an add????

Works like charm! However, can you tell me why the db is in negative?

Very usefull app thank you

Another great quick reference

Does what it claims. Good app.

Much better ones out there.

Great app that's simple and effective. I'd like an option to pay a small fee to remove the annoying banner adverts.

This apps help me a lot in my sound system setup

It's really accurate

Could you make a version that shows only the music your device is playing? Like a music visualizer?

Keep in mind this is limited by your phones or tablets microphone. Most can cover pretty high up (20khz) but most (if any) can't do it the low end frequencies. I can't seem to find solid info on the lower end for the galaxy s5 but I'm pretty sure it doesn't go down to 50hz

As a sound tech, it is not always easy to balance a sound board without a graphic equalizer. This app gives me that graphic so I can identify stray frequencies. That being said, it will not identify specific frequencies, but it does a great job of showing where the harmonies are. This app is great fun and a lot of help.

I'm an A/C tech by trade and an audio nut by hobby and passion. This app allowed me to quickly pinpoint the frequency range of an objectionable noise in a large commercial unit, and moving around allowed me to further narrow the area of the noise. Nice for rough estimating, but a professional tool is necessary for professional results. Mic in a phone is not going to be calibrated for pro use. Good app for the money (free) and gives you the basics to do what is needed on the fly for quick, basic work.

FrequenSee is a must-have app for instrumentalists. It allows a musician to see how his or her sound is broken into its parts (the fundamental pitch and the harmonic series). It is also great for achieving consistent dynamics throughout the range an instrument. It also has interesting implications for working on extended techniques (ie. multiphonics, whistle tones, singing and playing, etc.) I'm very excited to incorporate its use into my studio teaching and personal practice.

I was trying to explain to my daughter the difference between different sounds. 10 seconds on Google play and this thing is showing her the difference with a wiggly line. She played with it for 20 minutes and learned way more than me droning on (at 800 Hz, apparently). Next time she has a temper tantrum, I'm going to fire it up and measure her screaming.
