Audio Spectrum Analyzer
A handy real-time audio spectrum and spectrogram analyzer
新版本 3.1
Bugfix
Audio Spectrum Analyzer was designed with accuracy and ease of use in mind. It can be used for monitoring or measuring environmental sound or noise; help tuning instruments; timing short sound events; and educational purpose.
Features:
* No Ads.
* With log or linear frequency axis.
* Can label frequency axis using music pitch note.
* Support all possible sampling rates and almost all recorder sources of your device.
* Graph with nice grid lines and labels, easy to operate.
* FFT sample size range from 64 to 32768. Using half-overlapped (adjustable) time window to increase time resolution.
* Various window functions provided, for different frequency resolution and dynamical range.
* Peak frequency detection (in unit of Hz and note+cent), with a moderate accuracy (FFT + interpolation).
* With dB or A-weighting dB (dBA).
* Can record the audio in wav (PCM) format.
* Pinch to zoom, drag or swipe to move, long-press to place cursor, double touch to reset zoom.
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.
