Re: Digest Number 144 | Speech Coding

hi michael, I am a student currently working on the G.729 standard of ITU-T for speech compression. In that, it uses LPC 10 and converts the incoming input file (which can be a wav file) sampled at 8 khz to LPC 10 coefficients. you can refer to that standard for details of the required conversion. It uses the popular Levinson Durbin Recursion Algorithm for calculating the LPC coefficients. I dont know whether this would solve your problem but I have tried my best. If you want a copy of that standard plz let me know. However, I do not know of any tools which do the conversion but you can develop one using the algorithm. Regards Pratul O.
