Re: [Avid-L2] Re: True peak audio limiter

From what I understand:

While True Peaks are generally within +1dB over sample peaks, they can be as high as +3dB over sample peak.

One of the issues mixers had with the previous situation is that while they were mixing to a certain spec, the broadcasters still added Orban Optimod type limiters to their chains, meaning that what you ended up hearing at home, was not necessarily equal to the creative choices made in audio post. The new spec includes True Peak specification so that you can be sure that what you as a mixer hear and decide on, is in spec, and will sound as you intended.

True Peaks also matter because they may affect sound quality, either at the D-A stage, or – not unimportant these days – when the sound enters a lossy codec or needs to be sample rate converted.
