Octave Band Noise Generation No.2

Here is an example where our signal generation app "Octave Band Noise Generator" output 1/3 octave band noise of white noise from iPhone. It selected the following center frequencies (500-1000Hz and 4000-8000Hz) to generate a noise output signal.


This is the result of FFT analysis by our spectrum analyzer app "Audio Frequency Analyzer" . Since this FFT measurement result is an instant observation value, the flat characteristics can be obtained within the octave band on a time average.
As you can see in this example, it is also possible to bundle multiple octave bands and output noise.
