dBFS
– Used Only in Digital Systems – Fast Response with a Integration Time of 5ms – Intended to reflect when Digital Distortion will occur – Measures in dBFS – The Maximum Value in a Digital Scale is 0dBFS – often a Programs Fader Range goes from 0dBFS Down to -96dB (Wavelab, Dualism etc.) – in…

dBVU
– Volume Unit is an Analog Measurement – the “VU World” has often a Headroom of About +3dB Above VU Zero or Sometimes +6dB (+6dB was Already in the Distortion Area) – the Standard Calibration is 1.228 Volts, i.e. if you Let 1.228 Volts through your System, you would Wanna Set the VU Meter to…

EBU R128
General – EBU = European Broadcast Union – New Standard as EBU R128 = -23dB LUFS is Based on Measuring “Perceived Loudness”, instead Measuring “Peak Loudness ” – In Fact, R128 allows a True Peak Level of -1dBFS – means Not the Peaks are Relevant anymore, but the effectively Perceived Loudness or the Average Level…

FS (Digital Full Scale)
– Used only in Digital Systems – Fast Response with a Integration Time of 5ms – Intended to reflect when Digital Distortion will occur – Measures in dBFS – The Maximum Value in a Digital Scale is 0dBFS – often a Programs Fader Range goes from 0dBFS Down to -96dB (Wavelab, Dualism etc.)

Gonio Meter (Lissajous)
General – when Left vs Right is Out of Phase which Each Other, i.e. are Identical but have Opposite Polarity, then the Dot Moves Left and Right, this Corresponds to the Side Signal in MS Processing Main Usages 2) Detect Heavy Limiting when the Gonio Shows a Characteristic “Diamond” Shape – Clipping can BTW also…

Inter Sample Peak (or True Peak)
General – Imagine a 16 Bit File with Full Resolution Samples that actually Misses the Peaks in the Audio, so when the Audio is Re-Constructed the Peaks then Added Could at least be 3dB Higher than the Sample we had Not Take – so if we Work Closer to a Digital Headroom (e.g. Towards -1…
