This mobile application, Sound Analyzer Basic, provides real-time analysis of audio signals. It simultaneously displays frequency (Hz) and amplitude (dB) spectra, along with a waterfall view showing spectral changes over time and a waveform visualization. The app boasts high frequency measurement accuracy, typically within 0.1Hz of error in low-noise conditions. Key features include peak frequency display, touch-based display range adjustment, selectable frequency axis scales (linear and logarithmic), waterfall and waveform views, and a screenshot function. While supporting a high frequency range up to 96kHz, frequencies above 22.05kHz might be partially filtered out on many devices, potentially introducing minor noise. Some devices may exhibit increased noise at specific frequencies like 48kHz and 96kHz due to filter processing.

Six key benefits of Sound Analyzer Basic are:

• Real-time Spectral Analysis: Instant frequency (Hz) and amplitude (dB) displays for immediate audio signal analysis.
• Dynamic Spectral Tracking: Visualizes how audio signals change over time via a waterfall display.
• Waveform Display: Complements spectral analysis with a clear visual representation of the sound waveform.
• Precise Frequency Measurement: Highly accurate frequency measurements, typically within 0.1Hz error in quiet environments.
• Interactive Display Control: Users can easily adjust the display range via touch controls to focus on specific frequencies.
• Flexible Frequency Scaling: Choose between linear and logarithmic frequency axis scales for different data perspectives.
