This is a download from Spotify of the Dire Straits song ‘Sultans of Swing’

I did this to check out the LUFs measurement and took some snapshots along the way to show other mastering data.

These first three images are from about 2 minutes into the song. LUFS are loudness units gathered throughout the song for the whole song at the point of measurement. They say you are supposed to keep things around -14LUFS for streaming services, but it looks like they can be juiced a little, since this one is around -11.8 at about the 2-minute mark.

The sound field measurement is supposed to be above the 0 point – this song showed a fairly narrow sound field throughout – narrower than what I am used to mastering – good to know. You see this in the second image below. (If you download this docx file you can enlarge the images to see them better.

In the third image you see the overall frequency range balance. The blue green area was calculated for a bunch of ‘modern’ mixes and you should keep the line within this area.

Here are some more images:

The middle shows LUFS (a measurement of the overall loudness for the song), left and right are for smaller sections of time.

Here is the sound field showing stereo spread, followed by instantaneous levels (both peak and RMS)

Here is the spectrum at an instant in time (you see the 15Khz or so cutoff of the MP3)

Here’s the spectrum over time:

This is a history display of the loudness taken about 3.5 minutes in.

Here’s a final snapshot at the end of the song showing a LUFS for the whole song of -11.4.
