The circuit consists pego lamps of 10 sequentially mounted LED, 9V Supply yagn needed IC1A strengthen up to 100 times the audio signal and move IC1B. The sensitivity of the circuit can be adjusted by changing the value of R4. While the value of C4 was changed from 220 to 470nF. Each R9 input must be connected to the output pin of IC2.
