It can be used for monitoring or measuring environmental sound or noise; help tuning instruments; timing short sound events; and educational purpose.\n\n<br><b>Features:</b>\n\n* No Ads.\n* With log or linear frequency axis.\n* Can label frequency axis using music pitch note.\n* Support all possible sampling rates and almost all recorder sources of your device.\n* Graph with nice grid lines and labels, easy to operate.\n* FFT sample size range from 64 to 32768. Using half-overlapped (adjustable) time window to increase time resolution.\n* Various window functions provided, for different frequency resolution and dynamical range.\n* Peak frequency detection (in unit of Hz and note+cent), with a moderate accuracy (FFT + interpolation).\n* With dB or A-weighting dB (dBA).\n* Can record the audio in wav (PCM) format.\n* Pinch to zoom, drag or swipe to move, long-press to place cursor, double touch to reset zoom.\n\n<b>Notes: May need some knowledge of discrete Fourier transform and spectrum analysis to use it well. The actual accuracy mainly depends on your device. No calibration interface provided.\n","categories":["Multimedia","Recorder"]}
