sig = rangeexpand(insig,mu,sigweight);
rangeexpand(insig,mu,sigweight) inverts a previously applied \(\mu\)-law companding to the signal insig. The parameters mu and sigweight must match those from the call to rangecompress
rangeexpand takes the following optional arguments:
'mulaw' | Do mu-law compression, this is the default. |
'alaw' | Do A-law compression. |
'mu',mu | \(\mu\)-law parameter. Default value is 255. |
