I feel like saying thank You for giving CURVE EQ the audio world.
I am using CurveEQ for several situations in mastering. But for some time I was also working heavily on changing listening setups on lower SPL levels to be used in mastering as the most important first step is to find the right spectrum balance for every music in every genre.
Due to the strong effect of ISO226/Fletcher Munson I found CurveEQ as THE tool to be used in a mastering setup to make perfect basic EQ decisions on 10dB! lower listening levels from normed reference SPL levels (79 to 85 dB SPL), which are sometimes really annoying for sensitive ears.
CurveEQ appeared as the only tool to manage this job accurately!
