Little Morsels You Should Know…….METERS

Behold the Mighty Meter! – I see it but what does it mean?

I was thinking about this earlier today as I passed by some old 2″ tape machines.  Not many people understand metering these days.  You don’t see a VU meter that often anymore except when I’m mixing for a broadcast.  

What is a VU Meter?  Well it indicates the Volume Unit.  Often also referred to as a VI (Volume Indicator).  Other metering characteristics we run into are Peak Program Meter or PPM.  With today’s mixers we tend to see the PPM more often.  Although in today’s audio world it’s getting increasingly more difficult to find a meter that adheres exactly to a standard.  I used to use the VU or VI meter most of the time but now only when I’m at a broadcast station.  I still love them and they track the loudness component of a signal which is related to RMS. (Root-Mean-Square)  The zero reference on a VU is typically +4 dBu and the range is -20dB to +3 dB.  The meter is blind to peaks and is slow in response time.  Some used to also have peak LED included which I found especially useful.  

The PPM or Peak Program Meter tracks peaks of the audio, kind of….  The true peaks can exceed the indicated peak by up to 8 dB.  The meters tend to ignore quick short term peaks for which clipping would not be audible.  PPM’s are great for getting the full, usable audio level out of your device.  OK.  That’s geeky enough for now.  Perhaps I’ll delve deeper another
