Alright, just downloaded the new excel workbook and this is the graph it gave me after using the old measurements and leaving the filters as they were. Will do some tweaking at some stage, not today as it is a holiday here and do not want to upset the neighbours. Will tackle REW as soon as I can get hold of a suitable soundcard that is not too pricey! Feel free to comment but please note this is not the final graph, changes will be made at some stage.
