DECOMPRESSION
The files that were saved in point 4 of previous page, can be used to reproduce (a slightly degraded version of ) the original signal. You just need to type "reconstruct" at the command line .
You will be asked to select a valid file to decompress. Select a .mat file that is prefixed with "comp" . This is necessary, because only such files contain the information used by the MATLABŪ routines reading the files. Failing to comply with these instructions will lead to erroneous operations.
The reconstructed signal (with some distortion of course) will be written to the same directory as the source (ie the compressed and encoded .mat file). Its name has a prefix of 'recon' instead of comp.
eg : if the compressed and encoded file is compmydata.mat then the final wav file is reconmydata.wav.
Note: The .wav file obtained in this decompression process is the same as that obtained in step 5 of Saving data after compression
