Sudoku: Normal Sudoku rules apply.
Cells with a letter in the top left corner contain "Volume" digits.
Cells with the same letter in the bottom right corner are on a European Whisper line.
Adjacent digits on yellow European Whisper lines differ by at least the corresponding "Volume" digit.
There are no repeated "Volume" digits.
E.g. If R9C6 (Volume E) contained a 4, then adjacent digits along the European Whisper line that contains R9C9 must differ by at least 4.
Solution code: Column 2

I really liked the variable whisper "volume" concept. Bigger doesn't always mean louder :)
Excellent 3* puzzle.

Hard but very satisfying whittling down the different possibilities and how they impact each other. Thanks!
