matlab code for the audio acquire and display on the screen

i writing an free losless audio coder, faster on old 486 than flac or ape decoding on pentium 233 MHz !!! the program working, and compression ratio is equal to flac / ape ... On pentium 233 MHz flac decompress time is 26 sec of enya_.wav . ape is more than 45 sec... :) approx 14 sec coding enya.wav with pkzip, and my routines not have completed. My hope is 4 sec compression time, if completing, and decompressing a 16 bit stereo 44100 Hz is real time on 80286 cpu !!! PLEASE HELP ME ! i am an hungarian programmer, and i cannot wrtite in english perfectly. i not have time for write code for incoming 16 bit variable contents ! i want variable bit size putting into 8 bit foam. the 16 bit variable containing e.g. 7 bit valuable data, and 8 of this data must be storing into 8 bit datas. (code need 24 .. 2 bit incoming packing into 8 bit data.)-i writing an free losless audio coder, faster on old 486 than flac or ape dec
