|This page serves as a library of additional EQ curves that can be used in the Equalization effect in current Audacity.
Adding the Curves to current Audacity
- Right-click over any of the links to curves on this page (with yellow background), choose "Save Target as" or "Save Link As".
- As more advanced usage, if you left-click the link, some web browsers will display the XML on the web page which you could then copy and paste to a file.
- Save the file to any location on your computer. The best location to save to is inside Audacity's folder for application data as follows:
- Windows 98/ME: Windows\Application Data\Audacity
- Windows 2000/XP: Documents and Settings\<user name>\Application Data\Audacity
- Windows Vista/7: Users\<user name>\AppData\Roaming\Audacity\
- OS X: ~/Library/Application Support/audacity/
- Linux: ~/.audacity-data/ .
- Select some audio and choose .
- Choose "Save/Manage Curves...".
- Choose "Import...", select the .xml file you downloaded, then "Open" (if you did not save the file to the above location, you'll need to navigate to the correct location first).
- Click "OK".
Audacity Default Curves
If you are looking for these because you have no curves at all, download http://audacity.googlecode.com/svn/audacity-src/trunk/presets/EQDefaultCurves.xml and save to the location above.
If you just want a copy of the defaults, rename this download or you will overwrite any other curves that you currently have.
EQ Curves for old recordings
The 1.2 version of Audacity had a number of EQ curves for electrical 78 rpm discs and early LP's which are not offered in current Audacity. If you need these curves again, download http://wiki.audacityteam.org/w/images/4/4c/EQRecord.xml . Note that the RIAA and Inverse RIAA curves in this file are now deprecated.
More advanced users can visit 78rpm playback curves for a table of "bass turnover" and "rolloff" values for a much wider range of 78 rpm discs and other early LP's. EQ Curves for Audacity can be generated from those values using the instructions on that page.

- Gale: Curve(s) to compensate for non-flat frequency response in microphones. I suspect impractical, for reasons such as these.
Creating new Curves
All files should be XML that is readable by the "Save/Manage curves..." dialog in Equalization.
- The first line of the .xml file must be <equalizationeffect> and the last line of the file must be </equalizationeffect>.
- Each curve must have a first line in the form <curve name="name of curve"> and a last line </curve>.
- "f" points are the frequency in Hz and "d" points are the gain in dB (a dB value prefixed by "-" means a negative gain, that is a reduction in amplification).
Example .xml file:
<equalizationeffect> <curve name="default walkie talkie"> <point f="100.000000000000" d="-20.000000000000"/> <point f="125.000000000000" d="-16.000000000000"/> </curve> <curve name="modern walkie talkie"> <point f="102.000000000000" d="-15.000000000000"/> <point f="130.000000000000" d="2.000000000000"/> </curve> </equalizationeffect>
Files should not contain a curve called "unnamed" , but if they do it's not a disaster.
Files can be most easily be created by drawing EQ curves in Equalization, then choose "Save/Manage curves..." in Equalization and use the "Export..." button.
