It’s great we can store presets, trade them with other users, and download free ones. But…when selecting different Ampire presets to decide how they fit with a track, you want their levels to match closely. Then, your evaluation of the sound will be based on the tone, not by whether the preset is softer or louder. However, consistent preset levels are not a given.
Having a baseline level for presets, so you don’t need to change the level every time you call up a new one, is convenient. You can’t really use VU meters for this, because you want sounds to have the same perceived level, which can be different from their measured level. For example, a brighter sound may measure as softer, but be perceived as louder because it has energy where our ears are most sensitive.
My standard of comparison is a dry guitar sound, because I want the same perceived level whether Ampire is enabled, or bypassed. You might prefer to have Ampire always be a few dB louder than your dry guitar—whatever makes you happy.
The LUFS (Loudness Unit Full Scale) measurement protocol measures perceived loudness. LUFS measurements allow streaming services like YouTube, Spotify, Apple Music, and others to adjust the volume of various songs to the same perceived level. This is why you don’t have to change the volume every time a different song shows up in a playlist. The system isn’t perfect, but it’s better than dealing with constant level variations. Fortunately, Studio One has a Level Meter plug-in that gives LUFS readings (fig. 1).
We interrupt these steps to bring you an important bulletin: The Level Meter reading that matters is the INT field. This averages out the audio, so you’ll see the reading change at first, and then settle down to a consistent LUFS reading. When you change levels, call up a different preset, or make any changes, click on the Reset button to re-start the averaging process. When doing any LUFS measurements, you can’t be sure the reading is correct until you’ve a) hit Reset, and b) played the event several times, which is why we want to loop it.
We now return to the step-by-step procedure.
And while you’re at it, save the Song you used to do this testing. Then you can call it up again in the future, when you want to match preset levels.
Okay, so it took a little time to balance all your presets. But when deciding what preset to use in the future, you’ll be glad you set them all to a baseline level.
