Measure levels in real time using the device's microphone. Record audio clips for later analysis. Set decibel thresholds and receive notifications when levels exceed limits. View historical data and export measurements as files.
GPS-based digital displays current speed during driving, flying, cycling, or boating. Shows head-up display mode on car dashboard. Displays maximum speed limit and road name. Includes linear compass for direction.
Analyze in real time with octave band and FFT plots. Display sound levels in decibels and noise ratings. Choose linear or logarithmic scales. Adjust window functions and track maximum values.
The app performs direct addition or subtraction of decibel (dB) levels. It converts sound levels to a linear scale using an antilog function for calculations.
Measure sound levels with real-time precision. Analyze harmonics using multichannel FFT with adjustable parameters. Display graphical representations of audio data. Utilize AI to identify sound sources and analyze environments.
The app offers sound pressure level (SPL) measurement with industry standard response times and weighting functions. It also provides a real-time audio analyzer with selectable bandwidths and FFT block sizes.
Test audio output and input quality by playing sound waves and analyzing speaker clarity. Detect microphone issues through voice recordings. Clean speakers and or dust with built-in tools.
Measures environmental noise and displays values through a gauge and graph. Shows current noise reference and min/avg/max levels. Allows device-specific calibration. Displays data in multiple formats.
Use the speaker removal feature to play specific sounds that help eliminate the speaker. Create custom tones with the frequency generator. Measure sound levels in decibels and detect dominant frequencies using the built-in meter.
Remove from speakers using sound waves. Measure decibel levels to monitor volume. Display neighbor's audio output for visibility. Offer ad-free operation for uninterrupted use.
Record with high quality for meetings, personal notes, speeches, lectures, and songs. Save recordings without time limits. Manage files directly on internal storage. Adjust settings for optimal sound clarity.
Measure lengths with a virtual ruler. Use protractor, plumb line, and spirit level for angles and alignment. Check elevation, air pressure, and location. Monitor decibels. Convert ordinal dates to calendar dates.
Analyze in real time with octave band and FFT measurements. Visualize frequency spectra and measure sound levels. Export data and compare measurements across sessions.
Measure sound levels with readings. Analyze sound frequency with spectrum visualization. Generate custom tones for testing or experimentation. Save and share measurement data.
Measure levels in your surroundings with real-time readings. Display minimum, average, and maximum values. Show current noise reference and detailed data. Visualize levels through a graph for better understanding.
