As a newbie and a very senior citizen as well the first thi ng I wanted to do was records from cassette tapes, then be able edit with EQ and export to digital file. I gather from the iknfo that you can’t do this in Audacity yet, but can with 3rd party plug-ins. Does anybody have a list of these units and approx costs please.
You can apply Equalization in Audacity to the already-recorded waveform, but not in real time as you twiddle the effect parameters. You can tweak the parameters, preview what that sounds like, tweak again and preview again. When you like the sound you hear, you can apply the effect.
If you do want to tweak EQ while playing, you can try for example marvelgeq/ or there are some more you can look at here: http://www.vst4free.com/index.php?plug-ins=EQ.
These are all VST plugins. See here how to install VST plugins:
Install only VST2 32-bit plugins for use with Audacity. Not 64-bit, and not VST3.

Yes, Audacity comes with [u]Equalization Effect[/u]. I’d say the Graphic EQ mode is easier to experiment with than the Draw Curves mode. There is also a Bass and Treble effect.
You shouldn’t need any 3rd-party plug-ins unless you want something special or different.
Since EQ can boost the levels, after EQ it’s a good idea to normalize before exporting to make sure the peaks don’t go above 0dB. (You can use the Amplify effect with the default, or you can use the Normalize effect.) Audacity can go over 0dB, but most file formats will clip (distort) if you try to go over 0dB, and your digital-to-analog converter is also hard-limited to 0dB.
Or, you can go to View → Show Clipping (that may be on by default) or you can check the peak levels by running the Amplify effect, note the default Amplification, and then cancel the effect if you don’t want to make the change. The default amplification is the deviation from 0dB, so if you get a positive amplification value you are below 0dB and if you get a negative default value you are above 0dB and in danger of clipping when you export.
