About

Fun Spectrum Analyzer

Features
Read full description

Fun Spectrum Analyzer is a live audio spectrum and visualizer app for iPhone and iPad. It uses the device microphone to turn the sound around you into animated frequency displays, peak meters, waveform views, 3D spectrum graphics, radial analyzers, vector-style visuals, and colorful fractal-inspired motion. One mode is even inspired by 80s vector-based video games. We even have a safety meter inspired system that uses commonly known sounds as reference to compare against for loudness. Set alarms and get notified when the sound level is above your pre-determined safety level. The feature is for reference only, not scientific data collection. It is built for fun, music, rooms, parties, DJs, home audio testing, and anyone who likes watching sound come alive. Use it as a casual analyzer, a background visualizer, or a nostalgic display inspired by the glowing meters, spectrum analyzers, and hi-fi color palettes of classic 1970s and 1980s audio gear. Fun Spectrum Analyzer includes multiple visual modes, adjustable response controls, sensitivity, attack and fade behavior, peak displays, estimated SPL (Sound Pressure) readouts, theme-based color styles, and layouts designed for both portrait and landscape on iPhone and iPad. Safety mode includes the ability to set an alarm for when sound reaches beyond acceptable limits. This is a lightweight free-to-download, pay to unlock freemium app with no subscriptions, and no hidden upgrade costs. Buy the app once and enjoy the full version for life. We have gone out of our way to make sure use and enjoyment is as pain free as possible. After all, who needs PAIN when downloading apps? Note: Sound Analyzer is for entertainment and casual reference use. It is not a certified scientific, safety, legal, medical, or industrial measurement instrument. The developer and publisher of this app makes no promises, implied or otherwise, of the app's ability to produce scientifically reliable measurements.
