Hi Max, welcome where are you from (I can't see in your profile)

Think you have a reasonable idea how you would do it. Have you checked the tutorial section allready, There are several samples that contain code parts that I recognize in your project.

learn how to measure time wilt millis()

Here some code to get started...

void setup()
{
  Serial.begin(115200);
  Serial.println("Soundmeter 0.1");
}

void loop()
{
  // DO MEASUREMENT
  unsigned long startTime= millis();
  while (analogRead(A0) > 300);  // 300 threshold to be tuned  
  unsigned long duration = millis() - startTime;

  Serial.print("duration:\t ");
  Serial.println(duration);

  if (duration > 10000) // 10 seconds minimum value to be tuned
  {
     // wait 30%
     
    // switch on Relay 100%
    
 
  }
}

now it's your turn to finish it :wink:
