A few nights ago, I was struck by an idea that hadn't occurred to me previously. I was prepping for a presentation on loudness metering at a game development studio that would take place the following day. It was a question... Would bit rate or sample rate reduction affect the loudness measurement of sounds metered using ITU-R BS.1770? Both are practices common to game … [Read more...]
Loudness and Metering (Part 2)

Loudness and Metering (Part 1)
Guest contribution by Owen Green [This is the first of a two part series on loudness, mixing, metering and the new ITU loudness spec] Understanding the complex relationship between sound level and perceived loudness turns out to be very important to us as designers of sound for a number of reasons: Our perception of loudness is not constant (or even remotely linear) … [Read more...]
It’s Time to Talk About the Loud!

Whether you know what all of that means or not, … [Read more...]
