Sound Analyzer Basic

Sound Analyzer Basic is a mobile application that analyzes audio signals in real-time. It can display the frequency and amplitude of spectral components, as well as changes in the spectrum over time and sound waveforms. The frequency measurement accuracy is high, with a measurement error of generally within 0.1Hz in a low-noise environment. The main functions of the app include peak frequency display, touch-operated display range change, switchable frequency axis scale, waterfall view, waveform view, and screenshot function. The app allows the highest frequency setting to be raised to 96kHz, but settings above 22.05kHz are intended for devices with high-quality audio input. In most devices, data above 22kHz is filtered out, resulting in weak noise in the spectrum. However, certain frequencies may have larger noise due to filter processing.

The six advantages of Sound Analyzer Basic are:

- Real-time Frequency and Amplitude Spectra Display: The app can display the frequency (Hz) and amplitude (dB) spectrums in real-time, allowing users to analyze audio signals on their mobile devices.

- Spectral Changes Over Time: Sound Analyzer Basic can also display changes in the spectra over time using the waterfall view, providing a dynamic visualization of audio signals.

- Waveform Visualization: In addition to the spectral display, the app can also show the waveforms of the sound, allowing users to analyze the shape and characteristics of the audio signal.

- High Frequency Measurement Accuracy: The app offers high frequency measurement accuracy, with the measurement error generally within -1Hz in low-noise environments.

- Customizable Display Range: Users can easily adjust the display range of the spectra by touch operation, allowing them to focus on specific frequency ranges for analysis.

- Screenshot Function: Sound Analyzer Basic provides a screenshot function with a timer, enabling users to capture and save the displayed spectra or waveforms for further analysis or documentation.
