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
