House Curve Preferences

A "house curve" is a target response which differs from that defined by the bass management settings of the speakers. For a detailed description see the discussion in the REW forum at The House Curve Preferences allow a file containing house curve data to be loaded, or a curve that has been loaded to be removed. The selection is remembered for the next startup.

Defining a House Curve

The house curve is specified by a set of data that defines an offset curve that is added to the traces generated from the bass management responses for the speaker types defined for each channel. The file containing the house curve data is plain text consisting of pairs of frequency and offset values separated by spaces, tabs or commas. Interpolation is used between the pairs of values, either linear (default) or logarithmic, according to the state of the Use logarithmic interpolation check box. Logarithmic interpolation draws lines between data points which are straight if the frequency axis is logarithmic. The first and last values in the file are used for all frequencies below and above the range of the data respectively.

The house curve would typically be used to define a boost for the subwoofer range, such as that defined by the data points below. These points give a boost that is 6dB at 20Hz, dropping to 0dB at 80Hz and above. The boost remains flat at 6dB below 20Hz. A more elaborate curve might include a roll-off at high frequencies (if full range equalisation were being applied).
