Dear Expert
There are two questions, one is how to adjust AGC?
Another method is to send the data of ADCTLV320 to STM32, which then sends the audio signal to the DAC chip ssm3582a and plays it on the speaker. TLV320 is connected to a microphone, and we have found that if the microphone wire is relatively long, there will be obvious noise. If the wire is short, there will also be noise, but it will be relatively small. We would like to know what method can be used to eliminate noise?
