Dear Valin, Please, can you explain me the mean of the routines' parameters: 1. void vq_nbest(); 2. static void compute_weighted_codebook(); 3. static inline void target_update(); 4. void split_cb_search_shape_sign(); 5. void split_cb_shape_sign_unquant(); 6. void noise_codebook_quant(); 7. void noise_codebook_unquant(); and what they do briefly??? It's very difficult understand a code written by another person! I thank you in advance. ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

...gned > speex_bits_peek > speex_bits_nbytes > speex_bits_insert_terminator You probably don't need most of these, but I'm surprised you're not at least using speex_bits_init(), speex_bits_read_from() and speex_bits_write(). What are you using instead? > In cd_search.c: > noise_codebook_quant > noise_codebook_unquant No need for that (assuming you only want 8 kbps). > In filters.c: > compute_rms > syn_percep_zero16 > qmf_decomp > qmf_synth No need for that. > In ltp.c: > forced_pitch_quant > forced_pitch_unquant No need for that. > In math_approx.c: &...
