I'm hoping this might make a change from a mega-thread about "Audio
Precision" that is actually wandering all over the shop!... :-)

I've been experimenting with 'sox' to deemphasise audio CD data, and the
flexibility of sox set me wondering about using it to eq old EMI
recordings
that sometimes have an edgey quality to the strings, and lack low bass
because of their old fear of bass causing 'groove jumping'. Not
experimented yet, but wondered if anyone else has had a play with this.

In the trade, what you propose is sometimes called "mastering" if the
recording has not yet been released, and "remastering" if it has.

Compared to modern GUI tools, SOX's command line UI is pretty daunting from
an ease-of-use standpoint. Tools like Cooledit have been publicly released
and widely used for about 17 years.. If open source floats your boat,
Audacity would seem to be a massive step forward from SOX, especially if you
add one of the zillions of plug-in equalizers.
