The latest (still experimental) 78 RPM EQ Curve Generator can be downloaded by clicking this link.
Many moons ago there was a feature request for a way to import/export Equalization curves (without needing to manually edit the EQCurves.xml file). This feature is now available in the latest "Nightly" build of Audacity.
(see here for Audacity nightly builds - http://wiki.audacityteam.org/index.php? ... tly_Builds )
This new feature is implemented with a "Manage Curves" dialogue accessed by a "Save/Manage curves..." button. This button replaces the previous "Save As" and "Delete" buttons. "Custom" curves are now called "unnamed".
This is an opportunity for Audacity users to contribute Equalization curves they would like to be available either as "default" presets that all users will have, or as "optional" presets that can be specially imported.
"Manage Curves" provides an easy way to manage pre-set curves. You can save unnamed curves to the list of curves, rename, re-order or delete individual or multiple curves, and import/export .xml files containing individual or multiple curves. When you change the curves list, an automatic backup is made to EQBackup.xml, so if you make a mistake you can import that backup file. You can also restore the presets to the default set, which removes any customised curves you saved.
You can read the full story here: http://audacity.238276.n2.nabble.com/Be ... l#a4719919 .
- The new default curves set is not finished yet and so far only contains curves for amradio, acoustic and 60 Hz notch. EDIT:The Windows Nightly Build includes the preliminary default set EQCurves.xml in the same folder as the executable. On Mac or Linux you can download this default EQCurves.xml at "Proposed default curves" on: http://wiki.audacityteam.org/wiki/EQCurvesDownload . Place EQcurves.xml in your Audacity installation folder for Audacity to find it. Please paste new curves for the default set on: http://wiki.audacityteam.org/wiki/Default_EQCurves .
- There isn't yet a useful selection of optional presets to import. You can upload .xml files containing suggested optional curves for the library to: http://wiki.audacityteam.org/wiki/EQCurvesDownload
As an alternative to posting curves on the Wiki, you can post them here by making them into a zip file and uploading the zip as an attachment in replies to this topic. You can't attach .xml files directly to the Forum, but you can rename the .xml file with a .txt extension and add that as an attachment. (Please don't post curves as inline text in your post as they tend to be rather long and forum has a habit of messing up text formatting.)
