Equalization effect replaced in Audacity 2.3.3

In Audacity 2.3.3, the Equalization effect has been replaced by two new effects:
  • Filter Curve: An FFT (Fast Fourier Transform) filter, similar to "Draw" mode in the old Equalization effect.
  • Graphic EQ: A graphic equalizer, similar to the "Graphic" mode in the old Equalization effect.
The old Equalization effect is no longer available.

Note that in the new effects, the preset curves are now accessed via the "Manage" button, in "Factory Presets".


Improvements:

The new effects fix all known bugs that were in the old effect, including the crash bug when using the effect in Macros, the crash bug when deleting "unnamed", incorrect settings bug, and the disappearing control point bug.

The effects have also been simplified by replacing some options with fixed optimal values.


Bugs and Limitations:

When Audacity 2.3.3 is updating an older version of Audacity, the old Equalization effect will still be listed in the Effects Manager. This is because the Effects Manager is not yet able to clean out the listing of old effects that no longer exist. Hopefully this will be fixed in a later version of Audacity, though no fix exists yet.

The new effects do not yet support import / export of custom curves. This is a feature planned for the next Audacity release.

The sliders in the "Graphic Eq" do not display their center frequency values. Labeling the sliders is considered by the developers to be an "enhancement", and will hopefully be added in a later version. The frequency value for each slider may be revealed by hovering the mouse pointer over a slider, and waiting for the Tool Tip to appear.


New Bugs:

If you think you have found a new bug in either of the new effects, please report them by starting a new topic in the Windows, MacOS or Linux board.
