Real Time voice compression using LPC

Started by Rudy Panjaitan May 4, 2004
I have a LPC (linear predictive Coding) listing, but it can't compress voice by real time. it only can compress a *.wav file. Does anyone know how to make it real time?
Thanks before. 



I  think your matlab code do the simulation for the  voice compressing using LPC,but it works the same principle as the Real Time Compressing.You code should do the code and uncode work at a same time,and you could not understand the LPC premeter by you ear,for we can only hear wave voice,so the matlab code only store the uncoded voice in  *.wav format on the computer,which gerneral voice play can play and you can hear.
If you can find out the input LPC premeter of the uncodec system,perhaps it is what you want,which is error-protected coded and transfered on the channel.
Also,I think there is  a few difference between you matlab implementation and the C reference code for the Real Time implementation ,which you can get from UTI website.
