Attention summary
No attention regions in current frame.
CWT helps read transients, tails and frequency movement with multiscale resolution.
How to read this view
- Vertical fast transients or attacks
- Horizontal sustained tones, harmonics or resonances
- Diagonal / curved sweeps, glissandi or frequency movement
- Persistent LF possible low-frequency tail or resonance
- Ridge dominant energy trajectory
- Attention regions worth inspecting
STFT uses a fixed window. CWT uses scale-dependent windows: that is why it shows fast events and low-frequency evolution with different visual emphasis.
Band alignment analysis
Enable Ridge to see the diagnosis.
The temporal centroid of the sub band (20-60 Hz) and the mid band (120-500 Hz) should match within +/-0.5 ms. A larger delta indicates crossover misalignment. Dashed lines mark band edges and circles highlight centroids.
