Recording Levels
General – Try to Set Recording Level for Mic/Line to approx. -18dBFS RMS/Average Volume (Not Peak) for the Sweet Spot, this translates to the Zero in a Analog Domain where Recordings also had to be Done Matching the -0dBVU as close as possible without Clipping and still provides Great Results – be aware that the…

RMS
General – Measures the “Root Means Squared” of a Signal – a Mathematical Way of Expressing the Amount of Energy in a Signal – Used in Analog & Digital Devices – Measures in dBu (as Peak) – Slow Response with a Integration Time of 50ms – Represents an Average of the Total Signal and is…

Short Term Loudness
– Provides More Detailed Loudness Information by Measuring the Signal More Frequently (Like to a Traditional RMS Meter) – i.e. the Loudness History Curve Draws Much More Movement in Short/Momentary Term, where a Integrated Loudness Curve Reacts Quiet Slow – Short Term Integrates Averages of Loudness Over the Last 3 Seconds (i.e. Averaging the Loudness…

Signal Flow
General – How to Preserve a Clean Routed Signal Inside a DAW 1) Processing Order – Pitch Correction Tools Need the Best Possible Audio Resolution to Work with, that is why they Appear on Top of the Routing Chain – EQ can also be Placed before a Compressor, but always Keep in Mind that Changing…

SPL (Sound Pressure Level)
General – Variations of Ambient Pressure caused by a Sound Wave – 20 Micro Pascals – Logarithmic Measure of the Changes in Pressure Relative to a Reference Level – Threshold of Human Hearing, means a SPL Meters “Ear” (Input Threshold of Microphone) is similar to our Ears Reaction on Real World Sound Waves / Noise…

VU
– Stands for “Units of Volume” – a Metering Unit to Measure a Signal Level Volume – Mostly in Analog Devices – Slow Response with a Integration Time of 300ms – Ignores Signal Peaks – Works Similar to the Human Ear, thus a VU Meter is Useful During the Mixing Process – Intended to Reflect…
