Rhapsodio Return Scorings

Average Technical & Tuning Grades

Average Tunign Grade

D
  • The tuning lacks refinement, jumping between dull and shouty without settling. Vocals frequently sound off-kilter.

Average Technical Grade

E-

Expect adequate midrange presence with a touch of grit and unevenness. Textures smear when the mix gets busy.
Treble E-
Upper frequencies retreat, causing detail and brilliance to disappear. You may think your source is covered.

Subtle shifts disappear, with transients lacking bite or urgency. Drum hits arrive without conviction.
