Hi.......My question is that i extract some part of .mfc files which i change to a simple .txt file. In short lets say that a wave file has 300 frames and i want to get the one from 100 to 120. so i use cepview and then append it to a .txt file. Now i want this .txt file to be converted into the binary format which can be recognized by Sphinx......Any clue from any one on how to do it.
Sincerely
Tanmoy

It's rather trivial to write a C program that will read a text file and dump a binary file. The format of mfc file is trivial. It's a header with the length of data and a float data in binary form each for 4 bytes.
Write header
outfp = fopen ("result.mfc", "wb");
{
int fcount = nframes * 13;
int swap_count = bswap_32(fcount);
fwrite (&swap_count, 1, 4, outfp);
}
write data
for (i=0; i<nframes;i++)
for (j=0;j<13; j++)
fwrite (&frame[j], 1, 4, outfp);
close file
fclose(outfp);
that's all.
