cosmetic change

I am tired of seeing Serial.begin(9600); where 9600 is not going to be
used at all. Can Serial.begin(Serial.baud()); be acceptable?

examples/MonoPeakMeterAnalog/MonoPeakMeterAnalog.ino

 
 void setup() {
   AudioMemory(4);
-  Serial.begin(1);
+  Serial.begin(Serial.baud());
 }
 
 elapsedMillis fps;

examples/StereoPeakMeter/StereoPeakMeter.ino

   audioShield.inputSelect(myInput);
   audioShield.volume(75);
   audioShield.unmuteLineout();
-  Serial.begin(1);
+  Serial.begin(Serial.baud());
 }
 
 elapsedMillis fps;
