Metering is the process that helps visualize the gain of instruments when recording, the loudness of the tracks when mixing, and the dynamic range of the mixes when mastering. This lesson explains the metering of audio signals the me most commonly use in mastering. Metering the peak, RMS levels or the spectrum content and stereo separation is very common.
This lesson explains the level metering of audio signals. Peak level is the momentary level of audio in any given moment. RMS level is the average level of an audio signal. LUFS is a unit that describes the average level of audio correct using weighting to adjust to human hearing.
This lesson explains exporting audio after the mastering process is done. Depending on the medium of distribution the audio is exported to adhere to different parameters required by the platform it will be distributed on.
