Analyse de l'application Sound Analyzer Pro pour le 28 septembre

Sound Analyzer Pro is an ad-free app that lets you analyze audio signals using only your phone or tablet. It displays the frequency spectrum in real time and includes a waterfall view for tracking spectral changes over time and a waveform view for displaying the audio waveform. Advanced features include Max Hold, Note Display Mode, and audio source selection. When analyzing a stable, single-frequency tone in a low-noise environment, the app can estimate the peak frequency to within approximately 0.1 Hz using the default settings. Results depend on the device's microphone, audio processing, and input signal quality. Key Features - Real-time peak display for the frequency (Hz) and amplitude (dB) of prominent spectral components - Touch gestures for adjusting the display range - Logarithmic and linear frequency scales - Max Hold - Waterfall view for tracking spectral changes over time - Waveform view for displaying the audio waveform - Note Display Mode with note names from A through G♯ and pitch deviation in cents - Audio source selection - Screenshots with an optional timer - No ads About High-Frequency Spectra The maximum frequency can be set as high as 96 kHz, but settings above 22.05 kHz are intended for devices with high-quality audio input. Most devices filter out signals above approximately 22 kHz. Increasing the setting cannot recover signals removed by the device, so it is normal to see only faint noise below −60 dB in this range. On some devices, audio processing may produce stronger noise at specific frequencies, such as 48 kHz or 96 kHz.
