Audio Techniques|Speaker Test vs AcousticApp

Audio Techniques | Speaker Test A professional audio testing toolkit for sound engineers, AV installers, and audio enthusiasts. Test Signals Play pink noise, frequency sweeps, clicks, and 1kHz sine wave test tones with polarity flip to verify speaker wiring and phase alignment. Real-Time Analyzer (RTA) 31-band 1/3-octave spectrum analyzer with peak frequency detection. Measure room acoustics, identify feedback frequencies, and verify system response in real time. Noise Generator Generate white, pink, or brown noise for speaker testing, room tuning, and sound masking. Tone Generator Sweep from 20 Hz to 20 kHz with sine or square wave output. Preset frequencies for quick access. Verify driver response, find resonances, and test frequency range. Key Features • Polarity test with L/R channel inversion • 31-band 1/3-octave RTA with peak hold • White, pink, and brown noise generation • Sine and square wave tone generator with logarithmic frequency control • Preset frequency buttons for common test points • Clean, intuitive interface designed for field use

AkustikApp by objectiv is a precise sound measurement app for iOS, developed in Germany. It supports sound, noise and room acoustics measurement, evaluation and documentation. The app provides a professional measurement tool with RTA display for sound and noise measurement. Measurement values can be saved as screenshots and used for documentation. This makes AkustikApp suitable for capturing acoustic situations in offices, daycare centers, schools, meeting rooms, public spaces and private rooms. The app can also be used for orientation and documentation of environmental noise, such as traffic or aircraft noise. The integrated acoustic measurement uses the device microphone to display relative level values and acoustic characteristics. In addition, the app provides information about acoustic products and solutions, including acoustic pictures, ceiling absorbers, wall absorbers and other products for improving room acoustics.
