frame=y ( [ (framesize* (i-1)+1):framesize*i]); end. end. You overwrite all of frame in each iteration. If that is your intention, you might as well do only the last iteration, i=M. Likewise your later code overwrites all of frame1. X=dct (y,32768); Your y is a vector so your X is a vector. A=idct (X,32768);

y = him'; Y = dct (y); [YY,ind] = sort (abs (Y), 'descend' ); need = 1; while norm (Y (ind (1:need)))/norm (Y)<0.999 need = need+1; end ypc = need/length (Y)*100; Set the rest of the coefficients to zero and reconstruct the signal from the compressed version.

The Discrete Cosine Transform is a first-level approximation to mpeg audio compression, which are more sophisticated forms of the basic principle used in DCT. This discrete cosine Transform Audio Compression is performed in MATLAB. It takes a wave file as input, compress it to different levels and assess the output that is each compressed wave ...
