* Fixed issue where Sweep measurements were low quality when using older test signal files. If you are using a test signal from v6.0 - 6.0.1, please export a fresh file to avoid low quality measurements. * Fixed issue where Sweep measure button did not update when enabling external stimulus.

* Fixed issue where re-sampled FIR filters had slightly different magnitude responses (thanks to Kenneth for reporting this :-)

HouseCurve 6.0 adds a real time measurement tool. Use it to live tune graphic equalizers and subwoofers or capture moving mic measurements (MMM) for use with the Equalize tool. Additional changes: * Improved menu system makes better use of screen space on iPads. * Measurement data files are now accessible via the app document folder. Users can copy measurement files to other devices or back them up. * Measurement management moved to a separate tool. This lays the ground work for a nicer view / compare features in the future. * The Tuning Bundle can now be purchased for one year (non-renewing subscription) or a lifetime unlock. Existing purchases are all considered lifetime unlocks - thank you for your support!

* This release adds some anonymous metric collection to help improve features and debug issues. Thanks to all the users that have provided suggestions and feedback over the years, I really appreciate it :-)

* Equalize Tool can now export room correction filters to Crestron DM NAX audio systems

* Fixed issue where measurements were inaccurate above 2 KHz (this was introduced in the 5.2.2 update last week)

* Fixed issue where some users could not restore purchase from app store

* Fixed issue in iOS 18.x where HouseCurve is unable to measure after taking over an AirPlay connection.

* Equalize Tool can now use shelf filters when generating PEQ based corrections. In some cases this can produce better corrections with fewer filters. * Equalize Tool displays the maximum boost applied by the correction. This can be used on systems that require headroom adjustment after applying EQ (ex: Roon) * Measurement sweep fades in more gently to be kind to audio systems without infrasonic filters. * Fixed an issue where measurement export could occasionally crash the app.

* Fixed issue where help screen would not display housecurve.com website

* Fixed issue where PEQ filters may not be generated when "allow only cuts" was enabled. * Fixed issue where exported impulse may not match measurement. * Updated microphone compensation for devices supported by iOS 16.x. * A warning appears when connecting to an audio system and iPhone / iPad device volume is high (this can be disabled). * Connection prompt remains hidden if active measurements are present. * Help screen has a link to HouseCurve facebook group.

* Fixed issue where PEQ filters could not be generated when the frequency range was narrow. * Added support for comma separated calibration file (ex: Audio Frog mics). * Minor visual tweaks.

* Equalize Tool can generate FIR filters for high fidelity room correction. FIR filters are compatible with Roon, HQPlayer, Volumio, CamillaDSP, etc. * Produce "cut only" filters for improved gain management * Set maximum Q for PEQ based room correction * Improvements for manual target curve fitting

HouseCurve is now free * Free version is perfect for quick frequency response measurements of your audio system * Additional features, such as room correction filter generation, advanced measurement tools and target curve editing can be obtained via in-app purchases.

* Choose which internal iPhone / iPad microphone is used for measurements. * Internal microphone can be used even when an external input is detected. This is useful when connecting to USB devices (ex: DACs) that appear as input and output to the iPhone / iPad. * Input status shows USB microphone names when available. * Fixed issue where curve source editor would not properly scroll when keyboard was active.

* Reduced chance of measurement failure in rooms with a lot of reverb.

* Fixed issue where stimulus type and delay setting would not persist between sessions.

* Saved measurements can be exported as impulse responses (.wav) for use in other tools. * Equalize tool can export filters for all sample rates at once * Equalize tool generates filter impulse responses that are 500ms long (significantly fewer samples than previous version) * Miscellaneous UI tweaks

HouseCurve-4.0 adds the ability to edit target curves by dragging and dropping points or directly editing the curve file. HouseCurve ships with two classic target curves: B&K and Harman. For additional curves, please visit housecurve.com Additional changes: * Improved target curve automatic fit * Export room correction filters with sample rates of 176.4 and 192 KHz * Better handling of large / accessibility fonts * Corrected issue where measurements would not save

* Minor cosmetic tweaks to UI

* Equalize tool can export filter impulse response for convolution based room correction (ex: Roon, CamillaDSP)

* Fixed issue where equalization target curve was not auto-fitting correctly in some situations

HouseCurve-3.0 adds automatic equalization / room correction for parametric equalizers. Just measure, choose a target curve and export the filter settings. For more information, https://housecurve.com/TUNING.html Additional changes: * Interface streamlined for faster setting access and new tools like equalization. * Features renamed to more common terms (ex: reference curve -> target curve). * Fixed issue where sharing an AirPlay connection with another app could cause HouseCurve to terminate unexpectedly

* Added more links to help page, minor UI tweaks

* Fixed issue where stereo usb input channels could not be measured
