Loudness Control: Three Things to Watch

摘要

Here are three critical things to watch on the mixing desk and what you need to know about them for effective loudness control. 1. VU indicator. The VU meter (now in digital bar graph form) has been around for 80 years for a reason. It's predictable, with predictable integration times and predictable release times so you can predictably read volume units. Remember it is an averaging meter and the peaks are far higher than indicated. For this reason you can expect to have about 20dB of audio headroom above OdBVU to encompass them.
