The 5 Dimensions of Your Sonic Profile

LoudCraft evaluates your master across 5 perceptual dimensions. Learn what each measures and how to improve it.

LoudCraft evaluates your master across 5 perceptual dimensions. Learn what each measures and how to improve it.

Each dimension is scored on a scale where higher means more of that quality. The engine measures real audio properties - not subjective opinions. Here is what each one tells you and what you can do about it.

1. Warm low-end

Measures sub-bass presence, bass body, phase coherence in the low end, and low-mid cleanliness. A high score means your bass is full, tight, and clean. A low score means the low end is thin, muddy, or out of phase.

Tip: To improve: check your mix's bass in mono. If bass disappears in mono, you have phase issues. Use LoudCraft's Bass slider to add low-end body, or try the Warm mastering style.

2. Controlled highs

Evaluates the presence zone (2-5 kHz) and air band (12 kHz+). A high score means smooth, extended highs without harshness. A low score means the highs are either too aggressive (listener fatigue) or too dull.

Tip: To improve: if the score is low due to harshness, try the Natural or Warm style. If it is low due to dullness, try Bright. The Tone slider lets you fine-tune in real time.

3. Wide stereo

Measures stereo width and mono compatibility together. The best score goes to masters that are wide AND fold down cleanly to mono. A narrow mix or a wide mix that cancels in mono both score lower.

Tip: To improve: use the Spatial Intensity control on the home page. Check the Mid/Side analyzer in Compare - if the side signal is very loud relative to mid, you may have mono compatibility issues.

4. Transients

Evaluates dynamic range through the peak-to-loudness ratio (crest factor). A high score means punchy, defined transients with room to breathe. A low score means heavy compression has flattened the dynamics - kicks and snares lack impact.

Tip: To improve: this is mostly determined by your mix. If you already have a limiter on your master bus before uploading, remove it. LoudCraft's limiter is designed specifically for mastering and preserves more transient detail.

5. Streaming loudness

Measures how close your master is to the selected platform target. Within 0.3 LU is excellent - the platform will not adjust your volume. Beyond 1.0 LU, the platform will normalize your track, which can change how it feels next to other songs in a playlist.

Did you know? Being exactly on target is not always ideal. Many engineers intentionally master 0.5-1 LU above the streaming target. When the platform turns you down, your dynamics are slightly better preserved than a track that was pushed to the exact target with heavier limiting.

Key takeaway: The Sonic Profile is not a grade - it is a map of your master's character. A perfect score in every dimension is not the goal; the right balance for your genre is.
