Sound Analyzer: Spectrum & Hz

Sound Analyzer analyzes audio from your microphone in real time using FFT, and displays the frequency spectrum visually. Perfect for noise surveys, acoustic checks, and environmental measurements. 【Features】 ■ Real-Time Spectrum Display Live FFT analysis from the microphone. Simultaneously shows peak frequency, peak amplitude, and RMS level. ■ Audio Recording & Playback (Pro) Record audio while measuring. During playback, the original FFT spectrum is recalculated in real time. Linear scale display is also supported. ■ GPS Location Tagging (Pro) Automatically attach location data to recordings and measurements. View where each measurement was taken on a map. ■ Memo & Tag Management (Pro) Add memos and tags to each recording for easy organization.
