Inverse pink noise Arithmetic

[Ballle Clorin]

Pink noise is common test signal but generates a sloped frequency amplitude recording, It would be nice to be able to "invert" the pink noise result back to a flat response. may be a new trace arithmetic?
At present I did it by importing to excel and doing the the math in an amateurish way. Doing it in REW would be useful i think, sweeping and sending signals to the Hifi not always possible or convenient.
But using streaming pink noise or CDs may be possible
By the way Audiotools does the pink noise conversion in the app... so the pink noise signal look flat in the plot

The RTA is generally the appropriate tool to analyse a noise signal. Pink noise is flat on an RTA.
