Waveform asymmetry and how to fix it

Tracks laid down by our bass player are badly asymmetric. But to be clear not at all DC Shifted (see attached)
I saw this UTube related to ‘Audition’ which provides a Graphic Phase shifter that can fix this simply.

Can this be done with Audacity? I see some suggestions that the ‘Phaser’ Effect can do it but the interface is oribly complex, and I would have no idea where to start.
Can it be done and if so how
Cheers

You can apply an “All-Pass filter” to the track. This requires some experimentation because the results (like the “Graphic Phase Shifter” in the video) are unpredictable.
Run this code in the Nyquist Prompt effect (see: https://manual.audacityteam.org/man/nyquist_prompt.html)

(allpass2 *track* 100 1)

The numbers “100” and “1” are just a starting point. If it doesn’t work very well, try changing the numbers.

Cheers Steve, I will give that a go.

Yes that works fine, a couple of passes with those settings is best.
Doesn’t get rid of that initial negative spike, nor does a Spike removal.
But then again I don’t hear it anyway.
