The problem
The hard part isn't mastering. It's knowing what to change next.
Export. Test it in the car. Compare. Change the limiter. Export again—v3, v7, final, final-final. Sonatio shows what the audio data is saying before you make the next move.

Analyzing dynamics...
Analysis depth
The decisions come from the audio data.
These measurements are the source of truth Sonatio uses to explain the master and recommend the next move.
Stereo and phase
Check whether width translates safely to mono and where phase needs attention.
Stereo Field
Stereo Takeaway
Width at 33.7% is narrower than the reference. Phase relationship reads mono-safe, so widening should stay deliberate and matched-level.
Dynamics
Understand movement, transient strength, and compression readiness.
Peak vs RMS
Dynamic Range
Dynamics Takeaway
Dynamic range is very open for Indie Pop and should be preserved through transparent loudness work.
Peak safety
Identify clipping risk and available headroom before limiting.
Clipping
Peak Safety Takeaway
Peak safety needs attention before mastering. Clipping or ISP activity is present, so ceiling control should be tightened before loudness moves.
Spectral findings
Find masking, harshness, and tonal imbalances before they intensify.

Audible Read
The 4.2-17.7 kHz harshness cluster may become edgy under limiting; treat it as a conservative matched-level excess-edge check.
Loudest window
Locate the passage where limiter stress and artifacts are easiest to hear.
Loudest Window
Interpretation
The loudest section at 2:49–3:01 carries the track's peak energy, making it the most revealing passage for limiter stress, harshness, and clipping risk.

Key Tonal Read
Broadly balanced with a natural -2.9 dB/oct spectral tilt appropriate for Indie Pop. The low-mid resonance cluster may build density under limiting, while the air band sits +3% above the reference and should be checked for brightness at target loudness.
