Sound Analyzer Basic

Sound Analyzer Basic is a mobile application designed for real-time analysis of audio signals. It provides a comprehensive view of the audio signal by displaying the frequency (Hz) and amplitude (dB) spectra, as well as changes in spectra 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.

Key features of Sound Analyzer Basic include:

• Peak frequency display: Identifies and displays the dominant frequency in the audio signal.
• Touch-based display range control: Users can easily adjust the display range to focus on specific frequency bands of interest.
• Switchable frequency axis scale: Allows users to choose between logarithmic and linear scales for the frequency axis, offering different perspectives on the spectral data.
• Waterfall view: Visualizes changes in the frequency spectrum over time, providing insights into the evolution of the audio signal.
• Waveform view: Displays the sound waveform, offering a complementary view of the audio signal alongside the spectral analysis.
• Screenshot function: Enables 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, leading to weak noise in that range. Additionally, certain frequencies, such as 48kHz and 96kHz, might exhibit higher noise levels 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 the 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: Provides flexibility in visualizing specific frequency ranges of interest through touch-based control of the display range.
6. Optional frequency axis scale: Offers the choice between logarithmic and linear scales for the frequency axis, enabling different perspectives on the spectral data.
