Get equidistant intervals on approximated bark scale
Wikipedia says we can approximate Bark scale with the equation:
b(f) = 13*atan(0.00076*f)+3.5*atan(power(f/7500,2))
How can I divide frequency spectrum into n intervals of the same length on Bark ...

Looking for ODE integrator/solver with a relaxed attitude to derivative precision
I have a system of (first order) ODEs with fairly expensive to compute derivatives.
However, the derivatives can be computed considerably cheaper to within given error bounds, either because the ...
