Features & Capabilities

Pulse Echo Sonar Meter is an advanced Chrome extension designed to generate and analyze sound pulses using your device's audio output and microphone. It creates sound pulses and captures their echoes, allowing users to visualize echo signals as maps, time-series waveforms, or Fourier-transformed frequency data. This tool is ideal for educational, research, and acoustic investigation purposes.

Key features include high sampling frequency (44.1 kHz), customizable pulse generation (single, train, chirp; square/sine waveforms; Tukey/Hanning envelopes), and flexible pulse frequency and duration settings. Users can view echo maps in color or black and white, analyze frequency content via FFT with peak frequency detection and averaging, and save data in CSV format. Note: It requires microphone and storage permissions and is intended for acoustic explorations only — not suitable for medical imaging. Ear protection is recommended due to potential loud sounds.

User Reviews

Pulse Echo Sonar Meter is praised for its diverse sound measurement features and accuracy once settings are correctly configured, making it engaging for experimenters and professionals. However, it suffers from a complicated, poorly documented interface and often fails to measure distances reliably, with many users reporting persistent zero readings. Additionally, the app may freeze and has compatibility problems on some devices, making it challenging for average users to benefit fully from its capabilities.

Pros

Offers a variety of parameters related to sound and echo measurement, making it a fascinating tool for experimentation.
Provides accurate ranging when settings are properly adjusted.
Fun and interesting app to play around with for sound analysis and ultrasonic imaging exploration.
Appreciated by some users for measuring sound absorption and echo improvements in rooms.
Offers potential use cases such as impact echo testing for concrete and sonar applications like backing up vehicles.

Cons

Complex and confusing user interface with poor documentation and lack of clear user guidance.
Distance measurement functionality often does not work; frequently reported as always showing zero.
App is not very user-friendly and can freeze or lag after changing settings requiring restart.
Lack of proper instructions or explanations for abbreviations and functionalities leads to difficulty in use.
Compatibility issues reported on devices such as Galaxy S10e, leading to non-functionality.
