The state of the art in audio declipping has currently been achieved by SPADE
(SParse Audio DEclipper) algorithm by Kiti\'c et al. Until now, the
synthesis/sparse variant, S-SPADE, has been considered significantly slower
than its analysis/cosparse counterpart, A-SPADE. It turns out that the opposite
is true: by exploiting a recent projection lemma, individual iterations of both
algorithms can be made equally computationally expensive, while S-SPADE tends
to require considerably fewer iterations to converge. In this paper, the two
algorithms are compared across a range of parameters such as the window length,
window overlap and redundancy of the transform. The experiments show that
although S-SPADE typically converges faster, the average performance in terms
of restoration quality is not superior to A-SPADE
