Los archivos APK (Android Package Kit) son los archivos sin procesar de una aplicación de Android. Aprende a instalar sound-spectrum-analysis.apk archivo en tu teléfono en 4 sencillos pasos:
Sí. Proporcionamos algunos de los espejos de descarga de Apk más seguros para obtener el apk Sound Spectrum Analysis.
1. ESTIMATE THE TOTAL NOISE LEVEL BY USING THE SOUND WAVE MODE AT THE MAXIMUM VALUE.
2. • Automatic stop in the sound wave mode (when increasing or decreasing signal strength).
3. When the sound is almost inaudible, it is necessary to find the amplitude for the frequency of 1000 Hz on the spectrum (FFT size: 16384).
4. FFT size: 2048 (the accuracy of determining the frequency of ±12 Hz), 4096 (±6 Hz), 8192 (±3 Hz), 16384 (±2 Hz), 32768 (±1 Hz), 65536 (±0.5 Hz), 131072 (±0.2 Hz).
5. • Values of any point (for frequency scale and sound wave (at maximum detail)).
6. The beginning of the signal is not calculated accurately (just like with an automatic stop in the sound wave mode).
7. To interpolate the frequency of the peak, select the Gaussian window (the accuracy of determining the frequency can increase by 10-100 times).
8. You can calibrate your microphone by launching a signal generator with a sinusoid frequency of 1000 Hz on another device and making the volume very low.
9. • Calculation of the amplitude (in the list of peaks) using neighboring bins (to compensate for spectral leakage and use of the window).
10. The amplitude of the waveform can be changed in the sound wave mode.
11. Files with saved data (SavedData_[date]_[time].txt) can be copied to a desktop/laptop computer or transferred to another iPhone using iTunes.
