We consider the problem of separating the tonal and the transient components of an audio signal. We employ mixed norms with different groups on the analysis coefficients to formulate the problem. We provide an algorithm for the solution of the problem and demonstrate that the formulation can be effective for the given task. We also provide a brief discussion on the difference with a synthesis prior based formulation.
