اصدار جديد من تطبيق : DiGiPro SPL Audio Analyzer v4.0.1 (Paid) Apk لـ Android - تنزيل :
This application brings the functionalities of a Sound Level Meter (SLM) and a Real Time Spectrum Analyzer (RTA) to your phone. SPL (dB) of the microphone (internal or external) signal. Suitable for acoustic measurements: - SLM: traffic or ambient noise analysis (TNI dBA/dBB/dBC Leq) - RTA: audio equipment frequency response analysis (spectrum octaves peaks RMS) This app has much more features (+) than the basic edition (no ads). >>SLM main features: • measurements in SPL • 3 measuring modes (Dynamic Average Cumulative) + 3 weighting filter curves: dBA dBB dBC according to DIN-IEC 651 + fast & easy calibration page • sound level versus time chart • current dB value avg (Leq) min and max display • Leq (wideband RMS of the observation period) • audio threshold trigger + sound level distribution chart + accumulated sound level chart + current value Leq L90 L50 and L10 values display + TNI (Traffic Noise index) display + exporting of measures chart data (CSV) and screenshot (PNG) • tested with samsung galaxy • sharing of text values and screen bmp >>RTA main features: - measurements in SPL + 5 spectrum measuring modes (dynamic average peak avg/exp smoothing) - sound level versus linear frequency chart + sound level versus logarithmic frequency chart (HzLog) + 1/1 Octave Bands chart - 1/3 Octave Bands chart + Microphone Equalizer (Internal or External) in 1/1 Octave bands + calibration in 1/1 Octave bands + 2 spectrum views (Panel & Chart Landscape Chart) - tap or swipe to select the proper frequency step - long press to zoom - 4 values versus selected frequency component displayed (current Leq max min) + Leq (Octave RMS of the observation period) + Leq (selected frequency RMS of the observation period) - 20hz/22kHz band 44100 Hz sampling rate + adjustable FFT size (up to 8192 about 5 Hz accuracy) adjustable FPS (up to 20) + exporting of measures/chart data (CSV) and screenshot (PNG) >>Data collection The application relies on the mobile microphone signal. To achieve the best results consider the following: 1) Easy Calibration (only the first time): Some mobiles are automatically calibrated in the first installation phase. For details see the calibration section of the user manual. 2) keep your fingers away from the mobile microphone 3) silence your phone to avoid any ring tones vibrations and other sounds 4) orient the phone microphone toward the noise source keeping the correct distance 5) click on the function buttons >>Troubleshooting 1) Wrong SPL/RTA calibration: See the calibration section 2) No signals detected below 20dB or over 100dB: most smart phone microphones do not work under 20 dB or over 100 dB 3) Signal attenuation near band limits: the mobile mic may attenuate frequencies 15000 Hz .download apk android for windows .
