Mic spectrum

[naofumi39538]

Describe the bug:
the mic spectrum is incredibly slow, its like, 1 frame per sec

• Device used: m5stick c plus 2

Expected behavior:
same speed from the original firmware, the m5stick c plus 2

Actual behavior:
its so slow, i cant even see the noise properly in mic spectrum, everytime i snap my finger as sound to capture, its just one white lined frame.
