Audio Techniques|Speaker Test vs EarDial

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

Know the sound level around you, and how long you can stay safely. This app will tell you the approximate sound level pressure you are currently exposed to, and it will tell you how long you can stay at that level without risk of hearing loss. You can find inside more information about the decibel scale, the noise dose formula, attenuation standards, and more. This app was developed as a free companion for EarDial HiFi Earplugs - Invisible High Fidelity Hearing Protection, but it is useful even if you are not an owner of EarDial earplugs. You can compare the results if you are wearing EarDial earplugs or not. When you activate the EarDial switch, it will adjust the calculations based on the EarDial attenuation levels. You will be able to calibrate the app to your specific device if necessary. More information how to do that inside.
