There are no squealing violins in that file.

Everyone has different ideas of good EQ. We can't fix the file how you like it because we don't know what EQ you like.

So I suggest you open Effect > Bass and Treble..., try reducing the treble, press Preview, and if that does not sound right, try another setting, such as increasing the bass instead. When it sounds right, click OK.

" for the forum.wav" Sounds OK to me as it is .

But if you want to attenuate several narrow resonant peaks with an equalizer it's going to be difficult.
There is a free plugin for Windows , called DtBlkFx , which will do that automagically ...

it "clip"s the peaks in the spectrogram , (see next post).

This is how the creator of DtBlkFx illustrates the effect of "clip" ...
''clip'' effect on DtBlkFx , ( no I don't know what the walrus is for either).png

DtBlkFx's "clip" applies (downward) dynamic-range-compression to the spectrogram, (not to the waveform).

To my ears the processing introduces (or exposes) distortion in the last half.

But I have no clue what Zameen wants.
