The target curves is not correctly represented #839

Open gary-spec opened 2 weeks ago

gary-spec commented 2 weeks ago

Describe the bug The dBr values of the target curve are incorrectly represented, resulting in an incorrect equalisation

To Reproduce For example choose the "flat" target and set 20 Hz to be - 3dBr and 20 kHz to be -3 dBr. You will see that the line in the graph does not comply. I loaded in my own loudness equalisation curve as a target and the whole curve as about 1.5 dBr too low

Expected behavior The target curve should match the desired curve that is loaded

See here why this is the case. AutoEQ tries to minimize the average error between 100hz and 10khz, so it seems off-center in your example.
