AudioTools offers SPL measurement, RTA analysis, FFT visualization, and speaker polarity testing. Includes a generator, scope, CLF viewer, and recorder. Allows adding optional modules for advanced acoustic analysis and customization.
The app analyzes audio input in real-time using FFT. It displays the frequency spectrum with options for graph scale, FFT window, decay time, and amplitude offset.
Real-time analysis displays waveform and amplitude simultaneously. Users can switch between portrait and landscape modes. Options to configure waveform and display. Adjustable FFT size and window function for precise frequency analysis.
The app provides acoustical analysis for iOS devices. It offers octave and 1/3 octave modes with selectable decay times, Peak Hold, and true linear Average mode.
Measure levels in decibels using the device’s microphone. Display real-time audio frequency and dB readings. Apply filters for specific frequency and dB ranges. Share measurements via Messages, Email, WhatsApp, Notes, and other apps.
Realtime analyzer processes live input with Fast Fourier Transform and window functions. Record for offline analysis. Visualizer module displays frequency data from recorded files. Export analysis results and files.
Measure sound pressure levels precisely and easily.
The app transforms an iOS device into a sound level meter, measuring sound pressure levels. It offers features like Apple Watch support, Health app integration, and frequency analysis tools.
Analyze audio in real time with RTA bar and line graphs, FFT, and spectrogram views. Display peak and current dB levels. Choose linear or logarithmic scales. Adjust octave settings and access a sleek, functional interface.
