Sound Analyzer Basic

Sound Analyzer Basic is a mobile application designed for real-time analysis of audio signals. It offers a comprehensive suite of features, including the display of frequency (Hz) and amplitude (dB) spectra, as well as the visualization of spectral changes over time (waterfall view) and sound waveforms. The app boasts high frequency measurement accuracy, with a measurement error typically within 0.1Hz in low-noise environments.

Key functionalities include:

• Peak frequency display: Provides clear identification of the dominant frequencies in the audio signal.
• Touch-based display range adjustment: Allows users to easily customize the displayed frequency range for focused analysis.
• Switchable frequency axis scale: Offers the flexibility to choose between logarithmic and linear scales for the frequency axis, enabling different perspectives on the spectral data.
• Waterfall view: Visualizes spectral changes over time, providing insights into the evolution of the audio signal.
• Waveform view: Displays the sound waveform, offering a complementary view of the audio signal alongside the spectral analysis.
• Screenshot function: Enables users to capture and save images of the displayed data for later reference.

The app supports a high frequency range setting of up to 96kHz. However, it's important to note that frequencies above 22.05kHz may be filtered out in most devices, potentially resulting in weak noise in that range. Additionally, certain frequencies like 48kHz and 96kHz may exhibit increased noise due to filter processing in specific device models.

Here are six key advantages of using the Sound Analyzer Basic app:

1. Real-time frequency and amplitude display: The app provides immediate analysis of audio signals by displaying the frequency (Hz) and amplitude (dB) spectra in real-time.
2. Spectral changes over time: The app allows users to monitor the evolution of the audio signal by displaying changes in spectra over time.
3. Waveform visualization: The app offers a comprehensive view of the audio signal by displaying sound waveforms alongside spectral analysis.
4. High measurement accuracy: The app boasts high accuracy in frequency measurement, with errors typically within -1Hz in low-noise environments.
5. Customizable display range: Users can easily adjust the display range through touch operation, enabling flexibility in visualizing specific frequency ranges of interest.
6. Optional frequency axis scale: The app provides the option to switch between logarithmic and linear scales for the frequency axis, offering different perspectives on the spectral data.
