HouseCurve is a multi-tool for audio systems. Use it for room correction, adjusting equalizers, setting subwoofer phase, choosing crossovers and more. Features: * Sine sweep and real time pink noise measurements * Sweep measurements can be averaged as they are collected * Alternatively, use real time tool to collect moving mic measurements (MMM) * Compare measurements to a selected target curve * Create and edit target curves * Generate room correction filters (PEQ or FIR) * Filters compatible with a variety of systems including Roon, Volumio, CamillaDSP, EqualizerAPO, miniDSP and Crestron DM NAX * Display magnitude, phase and group delay * Use with built-in or external microphones * Connect with AirPlay, Bluetooth, headphone jack (analog) or use external stimulus HouseCurve measures in-room frequency response by listening to your audio system play a sine sweep. Measurements are displayed on top of a target curve, making it easy to see where adjustment is needed. Multiple measurements can be averaged to fully capture how the system sounds in the listening area. With small changes and repeat measurements, you can manually tune your system to the target curve. If your audio system has a parametric equalizer or convolution engine, HouseCurve can automatically generate filter settings to match the target curve. HouseCurve can help with home and car audio system tuning, from system equalization and room correction to subwoofer time alignment and speaker placement. Visit housecurve.com for more information on how HouseCurve works and how to use it. HouseCurve will produce acceptable results with the built in iPhone/iPad microphone. Using calibrated external microphones will provide higher accuracy. The free version of HouseCurve can measure your audio system and display a magnitude plot (aka "frequency response"). Additional features, such as room correction filter generation, advanced measurement tools and target curve editing can be obtained via in-app purchases.
