Understanding Spectrograms

A spectrogram is a detailed view of audio, able to represent time, frequency, and amplitude all on one graph. A spectrogram can visually reveal broadband, electrical, or intermittent noise in audio, and can allow you to easily isolate those audio problems by sight. Because of its profound level of detail, a spectrogram is particularly useful in post production—so it’s not surprising that you’ll find one in tools like RX 8

It is good to know how the spectrograms work. The overlay of the waveform is an added bonus.

  Toggle Pre-Fader Metering

Toggles between pre-fader and post-fader metering. The mixer visual changes with the meter to the left or right of the fader, left is pre-fader.

NB Pre-fader metering is post-insert — after all the plugins!

The level meters normally show you the signal level after the channel strip volume fader. This is the most effective way to use the level meters during mixing your project. However, you can also set the level meters to show you the signal level before the channel strip volume fader, called pre-fader metering. You may want to use pre-fader metering when you want to adjust a signal using the controls on your audio hardware before recording.

I have been reminded of how the channel strip meters work in Logic Pro. NB “pre-fader” is “post-insert”.
