Sound Analyzer Basic

Sound Analyzer Basic is a mobile application for analyzing audio signals in real time. It can display the frequency (Hz) and amplitude (dB) spectra, as well as changes in spectra over time (waterfall view) and sound waveforms simultaneously. The app has a high frequency measurement accuracy, with a measurement error within 0.1Hz in low-noise environments. Its main functions include peak frequency display, touch operation for changing display range, switchable frequency axis scale, waterfall view, waveform view, and screenshot function. The app allows for a high frequency range setting up to 96kHz, but frequencies above 22.05kHz may be filtered out in most devices, resulting in weak noise in that range. However, certain frequencies like 48kHz and 96kHz may have larger noise due to filter processing in some device models.

The six advantages of the Sound Analyzer Basic app are:

• Real-time frequency and amplitude display: The app can display the frequency (Hz) and amplitude (dB) spectra in real-time, providing immediate analysis of audio signals.
• Spectral changes over time: The app can also display changes in spectra over time, allowing users to monitor how the audio signal evolves.
• Waveform visualization: In addition to spectral analysis, the app can display sound waveforms, providing a comprehensive view of the audio signal.
• High measurement accuracy: The app has a very high measurement accuracy for frequency. In low-noise environments, the measurement error is generally within -1Hz.
• Customizable display range: Users can easily change the display range by touch operation, allowing for flexibility in visualizing specific frequency ranges of interest.
• Optional frequency axis scale: The app offers the option to switch between logarithmic and linear scale for the frequency axis, providing different perspectives on the spectral data.
