Pulse Echo Sonar Meter

Pulse Echo Sonar Meter is a cutting-edge tool that uses audio output to generate sound pulses, which are then captured as echoes using a microphone. This innovative app allows users to visualize echo signals on a map, analyze them with Fourier analysis, and view them as time-series waveforms. With options for single or continuous modes, as well as the ability to save data in CSV format, this app is ideal for exploring acoustic principles. Whether you're a sound enthusiast or simply curious about acoustics, Pulse Echo Sonar Meter provides a user-friendly platform to experiment, learn, and discover the fascinating world of sound waves.

Features of Pulse Echo Sonar Meter:

Multiple Pulse Generation Options: Users can choose from Single, Train, or Chirp pulses, as well as Square or Sine waveforms, and Tukey or Hanning Envelopes.

Colorful Echo Visualization: The MAP feature allows for echo visualization in color or black and white, with the ability to derive pixel values from RMS or absolute values.

FFT Analysis: Fast Fourier Transform is applied to 8192 data points for analyzing frequency content, with options for peak frequency detection and FFT averaging.

Data Saving Capability: Users can save data in CSV format, with time and date information included in each file.

FAQs:

Is RECORD_AUDIO permission required for the app to function properly?

- Yes, the RECORD_AUDIO permission is necessary to activate the microphone for echo detection.

Can I save data collected from the app?

- Yes, you can save data in CSV format, with each file being saved in the root directory with a unique number.

What is the typical microphone's dB range on most devices?

- The typical microphone's dB range on most devices may not effectively capture distant echoes unless additional amplification or a strong echo is present.

Can I visualize the sound for recent scans?

- Yes, you can create a map by moving the device while pulse-echoing to visualize recent scans.

Conclusion:

Pulse Echo Sonar Meter offers a comprehensive tool for exploring acoustics principles with various pulse generation options, colorful echo visualization, FFT analysis, and data-saving capabilities. With a user-friendly interface and detailed user guide, this app is ideal for educational purposes and experimentation. Experience the power of sound analysis with Pulse Echo Sonar Meter.
