Interesting - Filters and Meters in Pro Tools

This video shows that when filtering a signal, peak levels can increase, even though the volume of a sound decreases by removing frequencies from the sound. This proves that peak meters are inaccurate for measuring loudness and demonstrates that maintaining headroom is important during the audio production process.

The FLV of this looks and sounds terrible. Plus it sounds like Google's system is doing a bunch of auto level control which is killing the effect of this demonstration. :(

Very interesting, I want this to be one video in a series: "Matt's World of ProTools and Digital Audio...!" :)
