– a Logarithmic Unit to Express a Ratio

– 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…

– 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…

General – Distortion is the Result in a Change of the Shape of a Wave that usually Comes from Pushing a Particular Circuit Component (e.g. a Tube, Tape Machines, Amplifiers, Transistors, Transformers) Beyond its Limits or Linear Operation – i.e. when Signal Level Exceeds the Ability of a Device to Respond to the Level Swings…

General – it Looks at the Short Term Punchiness of a Track, Created Using a Ratio of the Short Term LUFS to Peak Level (Not the Same as Crest Factor which Uses RMS to Calculate the Dynamic Range) Crest Factor Large Crest Factors = will generally be of a Very Dynamic Material Smaller Crest Values…

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…
