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, spectral changes over time (waterfall view), and sound waveforms. The app boasts high frequency measurement accuracy, with an error margin of less than 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: Allows users to easily modify the displayed frequency range for focused analysis.
• Switchable frequency axis scale: Provides options for logarithmic and linear scales, offering different perspectives on the spectral data.
• Waterfall view: Visualizes spectral changes over time, revealing the evolution of the audio signal.
• Waveform view: Displays the sound waveform, providing a complete representation 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, potentially leading to weak noise in that range. Additionally, certain frequencies like 48kHz and 96kHz might exhibit increased noise due to filter processing in specific device models.

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: 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 displayed frequency range through touch operation, facilitating the visualization of specific frequency ranges of interest.
6. Optional frequency axis scale: Provides flexibility by allowing users to switch between logarithmic and linear scales for the frequency axis, offering different perspectives on the spectral data.
