Hello everyone, I'm finally beginning to use Speex for a project. As expected, the implementation so far has been very easy and I am thrilled with the capabilities and flexibility of Speex, especially the new features in 1.1. My efforts so far have resulted in a couple of questions: 1) I was interested in fetching the default quality setting for narrowband:

I haven't tested, but it looks sane. Just a few comments: - printf("\tERROR not enough bits left after wb\n"); this is actually now an error. It just means you got to the end of the

Use speex_mode_query with SPEEX_SUBMODE_BITS_PER_FRAME You need to pass the submode number with the pointer and the number of bits per frame is returned using the same pointer. Note that with speex_mode_query, the first argument is the mode (e.g. &speex_nb_mode), not the encoder/decoder state. Jean-Marc...

Hi, Ok, here is cleaned up and fixed version. * Function is named speex_get_num_frames() now and return number of frames, as you suggested. * WB layers sizes are taken from wb_skip_table[], while NB frame sizes are calculated with speex_mode_query(). I've tested it with testenc in NB, WB and UWB modes with VBR enabled to test in as many cases as possible. It seems to work fine. Though, while testing I discovered possible bug - original version of wb_skip_table[] (nb_celp.c:1081) does not seem to be correct. Element 0 should be 4 instead...
