Hi Amit, as US correctly points out to you, you have to give us enough information to help you. For example, the following call to wdencmp() is not complete [xc,cxc,lxc,PERF0,PERFL2] = wdencmp('gbl',C,L,wavelet,level,thr,'h',… You should give us information about the size of x (the frame you extracted from the audio as the input to wavedec() ) in the input call to: [C,L] = wavedec(x,level,'db10'); You should tell us whether wavelet_compression is 'on' or heavy_compression is 'on' I think then people will be able to help you.

Dear Amit! > > but where in WAVEREC does the error occur(?)... > > > i don't know exactly what happened with the code but m really confused and just need this.. Without a precise information it is impossible to solve the problem. You can obtain this information: 1. by reading and/or posting the complete error message, which contains the line number, where the problem occurres. 2. by letting the debugger stop in the corresponding line: dbstop if error Then start your function again. Matlab stops when the error occurs and you can inspect the variables in the command window manually. Some of your output variables are not defined! So search for undefined outputs. A general advice: If programming is "imp" for you, you definitely have to learn to use the debugger! Good luck, Jan |
