- /* CELP ARRAY SIZE PARAMETERS
- MAXNCSIZE maximum code book size (number of codewords)
- MAXL maximum codeword vector length
- MAXCODE maximum code book array length in samples
- MAXLL maximum LPC analysis frame size
- MAXNO maximum LPC filter order
- MAXLP maximum pitch prediction frame size
- MAXNP maximum pitch prediction order
- MMIN minimum delay pitch predictor (minimum value M)
- MMAX maximum delay pitch predictor (maximum value M)
- MAXPD maximum number of pitch delays
- MAXPA maximum pitch analysis buffer length (use to be "idb")
- (assumes code book is updated faster or same as pitch)
- MAXM2 maximum array size for delay parameter
