Sound Analyzer Basic is a mobile application designed for real-time audio signal analysis. It offers a comprehensive view of audio signals by displaying frequency (Hz) and amplitude (dB) spectra, spectral changes over time (waterfall view), and sound waveforms simultaneously. The app boasts high frequency measurement accuracy, achieving a measurement error within 0.1Hz in low-noise environments.

Key features include:

• Peak frequency display: Identifies and displays the dominant frequency in the audio signal.
• Touch-based display range adjustment: Users can easily manipulate the display range to focus on specific frequency bands of interest.
• Switchable frequency axis scale: Provides flexibility by allowing users to choose between logarithmic and linear scales for the frequency axis.
• Waterfall view: Visualizes spectral changes over time, offering insights into the evolution of the audio signal.
• Waveform view: Displays the sound waveform, providing a complementary view of the audio signal.
• Screenshot function: Enables users to capture and save images of the displayed data.

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, leading to weak noise in that range. Additionally, certain frequencies like 48kHz and 96kHz might exhibit larger noise due to filter processing in specific device models.

Six Advantages of the Sound Analyzer Basic App:

1. Real-time Frequency and Amplitude Display: Provides immediate analysis of audio signals by displaying frequency (Hz) and amplitude (dB) spectra in real-time.
2. Spectral Changes Over Time: Allows users to monitor the evolution of the audio signal by displaying changes in spectra over time.
3. Waveform Visualization: Offers a comprehensive view of the audio signal by displaying sound waveforms alongside spectral analysis.
4. High Measurement Accuracy: Delivers highly accurate frequency measurements, with an error typically within -1Hz in low-noise environments.
5. Customizable Display Range: Enables users to adjust the display range through touch operation, facilitating the visualization of specific frequency ranges.
6. Optional Frequency Axis Scale: Provides flexibility by offering the option to switch between logarithmic and linear scales for the frequency axis, allowing for different perspectives on the spectral data.
