But with so little allocation to low/mid frequencies, I'm not sure how I can separate things cleanly to show the frequency distribution graphically. I understand that audio is logarithmic, and the FFT works with linear data. Everything works, except the results from the FFT function only allocate a few array elements (bins) to the lower and mid frequencies. I run an FFT function on each buffer of PCM samples/frames fed to the audio hardware so I can see which frequencies are the most prevalent in the audio output. ![]() I am trying to build a graphical audio spectrum analyzer on Linux.
