1. An apparatus comprising:

  • at least one processor configuredto determine sparseness of an input signal in at least a time domain and a transform domain based on a plurality of parameters of the input signal,to compare the sparseness of the input signal in the time domain to the sparseness of the input signal in the transform domain,to determine at least one count based on prior selections of a time-domain encoder and prior selections of a transform-domain encoder,to select an encoder from at least the time-domain encoder and the transform-domain encoder based on the comparison and the at least one count, andto encode the input signal based on the selected encoder; and

    a memory coupled to the at least one processor.
