Simple recording noise canceling circuit

This article refers to the address: http://

First analyze the cause of the noise: Figure 9.29.1 shows a recording automatic level control circuit. D1 and C1 form a peak detection circuit. After converting the audio voltage at the output to DC voltage, the degree of BG1 is controlled to determine the size of BG1 shunting the output signal of the preamplifier through C2. Intermittent recording
