Sound Analyzer Basic is a mobile application designed for real-time audio signal analysis. 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 simultaneously.

The app boasts high frequency measurement accuracy, with a measurement error typically within 0.1Hz in low-noise environments. Its key functionalities include:

• Peak frequency display: Identifies and displays the dominant frequency within the audio signal.
• Touch-based display range adjustment: Allows users to easily modify the displayed frequency range for focused analysis.
• Switchable frequency axis scale: Offers both logarithmic and linear scales for the frequency axis, providing flexibility in data interpretation.
• Waterfall view: Visualizes spectral changes over time, enabling users to track the evolution of the audio signal.
• Waveform view: Displays the sound waveform, providing a complementary representation of the audio signal.
• Screenshot function: Captures images of the displayed data for documentation or sharing.

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

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

1. Real-time frequency and amplitude display: Provides immediate analysis of audio signals by displaying frequency and amplitude spectra in real-time.
2. Spectral changes over time: Enables users to monitor the evolution of the audio signal by visualizing 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 errors typically within -1Hz in low-noise environments.
5. Customizable display range: Allows users to adjust the display range through touch operation, enabling focused analysis of specific frequency ranges.
6. Optional frequency axis scale: Provides flexibility in data interpretation by offering the option to switch between logarithmic and linear scales for the frequency axis.
