hi guys im having a hard time with stereohead and im stuck at level 8. i know what i need to be listening out for (like hollowness towards 0.75-0.99 and singularity toward 0) but when i first start the game i can never seem to get it right and i can only get it right when i have a reference, like if i know the round before that was 0.4 i could guess 0.6 pretty easily but i wouldnt be able to guess either in isolation. any tips?
