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.

Don't know what sox is, but yes, I've done this kind of thing before
with Audition. I found a useful way to get it right, which was to take
a spectrum of the same piece, but a recording I liked and compare it
with the spectrum of the deficient one. Audition lets you draw
filters, and it was an easy task to construct one that corrected the
deficiencies. I did find that it was a good idea not to try and
correct too much, though.
