Sound Analyzer Basic is a mobile application designed for real-time analysis of audio signals. It provides a comprehensive view of audio data 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 an error of less than 0.1Hz in low-noise environments.

Key features include:

• Peak frequency display: Identifies and displays the dominant frequencies within the audio signal.
• Touch-based display range adjustment: Allows users to easily adjust 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 visualization.
• Waterfall view: Visualizes spectral changes over time, enabling the tracking of audio signal evolution.
• Waveform view: Displays the sound waveform, providing a complementary perspective on the audio signal.
• Screenshot function: Allows 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, such as 48kHz and 96kHz, might 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: 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 visualization by offering both logarithmic and linear scales for the frequency axis.
