. We apply recent methods of computing the joint spectral characteristics of matrices to find precise values of the H¨older exponents of Daubechies wavelets of order N ≤ 20. The local regularity of these wavelets is also analyzed. In particular, we find the points of the worst local regularity. In all cases they are rational, but not always dyadic.
