Filter type

Selects the type of filter HouseCurve will use to produce a correction.

When PEQ is selected, HouseCurve will generate a set of peak filters. These can be exported as PEQ settings, biquad coefficients or converted into an impulse response.

When FIR is selected, HouseCurve will generate a mixed phase FIR filter. FIR filters are exported as impulse responses.


The frequency range to equalize.

Use the minimum frequency to prevent the algorithm from correcting low frequencies beyond the capabilities of the audio system, ex: trying to boost at 20 Hz when the audio system can barely produce 40 Hz at -6 dBFS. Doing so will lead to distortion and possibly audio system damage.

The maximum frequency can be used to avoid wasting filters on high frequency issues that may not be audible.

Max gain

The maximum gain range filters (absolute gain).

The maximum gain limits the size of a boost or a cut an individual filter can make. HouseCurve may place filters in close proximity to produce larger gains. Keep in mind that a +10 dB adjustment means the audio system has to output 10 times more signal power.

Allow only cuts

Prevents the creation of filters with positive gain (boost) to avoid clipping. Use manual curve fit to lower the target curve and improve the overall correction without using boost.

Max filters

The maximum number of filters to use for PEQ correction. HouseCurve will allocate filters until the remaining corrections are outside of the frequency and gain settings.

For a parametric equalizer, set this to the number of filters your system supports. For a convolution engine (ie: using the impulse response), the number of filters just controls the fidelity of the correction. More filters may not make an audible difference.

Max Q

The maximum Q for PEQ filters, set this to the value your parametric equalizer supports. The “Q” of a filter is roughly the width. The higher the Q, the narrower the filter.
