Audio Spectrum Analyzer

오디오 스펙트럼 분석기의 응용 프로그램. 20 kHz까지 주파수를 표시 할 수 있습니다.

Audio Spectrum Analyzer turns your phone or tablet into an audio spectrum analyzer. Frequencies up to 20 kHz can be displayed, either with a linear or logarithmic frequency axis.

Tap your device's More Options button to bring up the settings:

You can control the displayed frequency span, as well as the FFT size, from 1024 to 262144 bins. The larger the FFT size, the longer time between updates, but the higher the frequency resolution.

Logarithmic display is available, and the graph fill mode can be turned on and off.

Up to five frequency markers can also be displayed.

You can select from 8 different windows:
