Q-factor is how wide apart your feet are when on the pedals. Q-factor
is a combination of the width of the hub, the amount that the cranks
flare out, and the length of the pedal spindle, and where your feet are
on the pedals.

Unicycle cranks tend to be straight and not flare out. Some unicycle
cranks have a little bit of flare though. Bike cranks tend to have a
lot of flare so the cranks can clear the chainstays on the bike.

Most people are talking about how much the cranks bend outwards when
they talk about q-factor on unicycles.

More q-factor in the cranks usually means you're going to hit your
ankles less on the cranks.

What about q-factor for audio? Do you play around with that much?

Never. I'm not even aware of the q-factor as it applies to audio.

Q factor is the angle of the crank from the axle to pedal. A larger Q
factor makes the uni wider from pedal to pedal then a smaller Q
factor.

Depends on the style of riding. For freestyle riding a small q-factor
in the cranks is better. For muni riding a larger q-factor can have
advantages since you're less likely to hit your ankles. For high speed
riding where you are spinning the pedals at a high rpm a smaller
q-factor is better since it causes less wobble in the wheel.

No, Q-factor is the distance the pedals are apart. The angle of the
cranks contributes to Q-factor, but it's only one of the factors. Even
straight cranks can have different Q-factors due to their width.

By the way, it's short for "quack factor", as in, pedaling with your
feed splayed out like a duck.
