Spectrum Analyzer RTA downloads
Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.
Active users
All platforms, worldwide. Free with an account.

how many monthly users open it on a given day
How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

Review momentum
ⓘ How we measure thisNew ratings a week
–
Apple's rating count fell over the last 4 weeks: it removed more ratings than came in (spam clean-ups, deleted accounts), so the pace can't be read right now
Lifetime rating
4.3★
recent stars not readable yet: new ratings are a tiny share of the total
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About Spectrum Analyzer RTA
***** "As a former IEEE Technical Committee Chair for Signal Processing, I find this app amazingly flexible and useful. Works very well with its proper designed-in control selections." - Roblake
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 X graphics
>>> Check out the demo videos at SpectrumAnalyzerApp.com
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.
