As can be seen in the figure, the circuit of the proposed audio spectrum analyzer consists of two main stages.The device will take line-level stereo audio input and display the spectrum on a bank of LED arrays. Audio is sampled via the onboard PDM microphone. The LED Spectrum Analyzer can display a real-time bar-graph spectrogram on a 20 x 20 LED display in four different ways.
Each of the 5 LEDs represent a single section of the chip’s 7 sections of audio spectrum. 15 (0) VU9 Mini IN9 Nixie Tube Sound Level Meter Music Spectrum Led Audio Spectrum Analyzer I always wanted to do something like this ) Arduino rules !
