EQ curves download
- Peter 08Mar15: I removed the yellow highlighting on the links, Connie does not ask for this and we don't do this with links anywhere else. I added display text to replace the explicit links.
- Gale 08Mar15: I can see why the gaudy background was added - the download link is in a random place in each section, making it hard to find. How about adding a bullet point for the download link at the top of each section? I tried that with one of the curve files.
- Peter -8Mar15: looked good so I adopted the same for the "A-Weighted Curve"
|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, 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 Vista and later: Users\<username>\AppData\Roaming\Audacity\
- Windows XP: Documents and Settings\<username>\Application Data\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 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
This file offers a number of EQ curves for electrical 78 rpm discs and early pre-RIAA LP's which were available in the legacy 1.2 version of Audacity but are not offered in current Audacity. Note that the RIAA and Inverse RIAA curves in this file are now deprecated.
- Download NAB transcription discs curve
This is the replay EQ curve of the American National Association of Broadcasters (NAB) for broadcast transcription discs. Published in 1942. Version for Audacity 2.1.2
- Download A-Weighted Curve
A-weighting is a commonly used curve defined in the International standard IEC 61672:2003. It was originally developed for measuring low level noise in audio equipment.

- 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.
