Spectrum Analyzer for iOS is a powerful real-time audio analysis app. Designed with musicians and recording engineers in mind, it can also be used by anyone interested in the world of sound. Ideal for room tuning or speaker tuning, the app enables portable, precision audio measurement and visualization.

Feature Highlights:
● Octave Band Real Time Analyzer
● FFT Plot (Fast Fourier Transform)
● Spectrograph module
● Test Tone and White/Pink Noise Generator
● Native iPhone 6 graphics

Audio input may be acquired via the built-in microphone or an external measurement microphone. For best results we recommend using a calibrated measurement microphone connected via USB audio interface or iPhone dock connector. This allows for high precision and flat frequency response, as well as for stereo input.

Pros and cons of Spectrum Analyzer RTA app for iPhone and iPad

Spectrum Analyzer RTA app good for

Im a sound engineer and I use this app all the time. Its not the cheapest, but it has a lot of usual features. Get it
Thank you for a well thought out, fast loading app. I wish I could send this to every church and every community theater in the country. How many people are frustrated with the performance of their sound system simply because they dont use their EQ properly because they have no idea how to set it? You can spend all the money you want on a sound system and it can still sound like a piece of crap just because the EQ is set wrong. Any sound engineer who has used a spectrum analyzer will immediately know what to do with the information that is displayed. I am the sound engineer at my church, and I have been the sound engineer on many of our community theater productions, and I use this app at least once a week, Usually more. Even when there is just a mild "ring" superimposed on a speakers voice, I can within seconds identify the frequency and use my parametric EQ to just dial it out. Additionally, when we set up a portable system somewhere, I can blow pink noise through the system and use this app to identify peaks and then flatten out the response with a 31-band graphic EQ before anyone even picks up a mic. Everyone and everything sounds good from the get-go. Makes me look real good! I remember the first portable analyzer I ever saw; it was from a company called Ivy; it was about the size of an iPad mini but about 3 inches thick and had a big silver analysis mic sticking out of the top of it like an antenna. It cost several thousand dollars and used a matrix of old-school red LEDs. Now I have a much better one on my phone that was either free or a couple of bucks. My, how things have changed.

Well-done app! Looks great on my iPad Pro and seems to do everything as-advertised. Definitely recommended.
Not complicated plus it includes a tone generator that generates different tones plus pink noise and white noise.

Some bad moments

Вылетает при переключении между программами, невозможно работать. Very good analyzer!! but... Dropouts!!! When working with mixer remote and switching between this analyzer and mixer remote program, analyzer didnt show up!!! Some times it does some times not, and its not workable situation while working on life stage. It takes about 5-10 times to try to turn it on. I have ipad 5 air, iOS 7.0.2 during the 5 month no updates!
As mentioned in previous reviews. Still not fixed. Works only in spectrograph mode. Feeling a bit ripped off since some newer reviews are positive, but fails date to late 2015 update.
Seems cool but keeps flickering hopefully they will fix it on a update!
No longer works with iOS 10. Doesnt look like the app is being updated either given the last update is pretty old.
As a former IEEE Technical Committee Chair for Signal Processing, I find this app amazingly flexible and useful. First test was to analyze the overly-noisy coffeehouse this morning. Worked very well with its proper designed-in control selections. I only wish that a spectrum could be captured and transferred to my Mac for further analysis and display.
Now that insurance companies have gotten into the hearing aid game, these devices have gotten far more capable, expensive, and complicated to tune. What i use to adjust with a screw driver at home now requires a computer and visit to the audiologist. And so after a life time of others controlling what I could hear, I found I was horrible at relating sounds to frequencies. So now whats bass, tinny, brassy, echo, reverb? All I knew was these $6000 hearing aids were by far the most expensive and worst sounding aids of my life! This app came to my rescue! So, now rather than having to say "my wifes voice is screechy loud, the tea kettle was blowing my ears, and yet i cant hear the train", and letting my audiologist guess the frequencies. This app put me in control by giving me a visual reference of the sounds around me. No more frequency guessing. I was blown away when I found my biggest issue. Every so often my ears would "yike", I had no idea if it was sound or defective aids. Twenty minutes into using this app my ears "yoked" just as this app indicated a loud high frequency narrow band clap! I had no idea of the source of the sound but I knew exactly what I did not need to hear! Combined this app with a media player app with a capable equalizer like "EQu" you can adjust, play, and see all you can hear. I found this app easy to use and give it top ratings. My audiologist will love this thing.

Usually Spectrum Analyzer RTA iOS app used & searched for

signal meter, rta audio, octave rta - real time sound frequency analyzer, and other. So, download free Spectrum Analyzer RTA .ipa to run this nice iOS application on iPhone and iPad.
