TOPIC:

I've just spotted what I believe to be a bug that was introduced by the new target curve type that has low and high-shelves (version 3.3.0 onwards). What I've spotted is that if this target curve type is selected, then dragging in the frequency curve 'curtains' does not stop all adjustments outside this frequency range as would be expected. Here's an example, first with a screenshot from the Dirac Live application and then with what the actual applied Dirac Live filter looks like (measured using USB loopback in REW). The both demonstrate that outside the selected range the filter matches the low and high shelf shapes rather than doing nothing as I at least would expect. As a solution, clicking 'Convert Shelves to Control Points' does limit all adjustments to the defined frequency range as expected.

 

 

Edit: I have contacted Dirac Live to raise this issue.
