...rts Speex (on MacOS X and Windows).. As it is now the user can set complexity (SPEEX_SET_COMPLEXITY) and quality (SPEEX_SET_QUALITY / SPEEX_SET_VBR_QUALITY) and to wether to use VBR or not. Will these options make it possible to produce all combinations of bitrates/qualities? Or should I also use SPEEX_SET_MODE/SPEEX_SET_LOW_MODE/SPEEX_SET_HIGH_MODE to accomplish this? /Pontus --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'speex-dev-request@xiph.org' containing only the word 'unsub...

Hello, In the internet draft describing the SDP parameters for speex I find this: mode: Speex encoding mode. Can be {1,2,3,4,5,6,any} defaults to 3 in narrowband, 6 in wide and ultra-wide. In the documentation I can only find the following request: SPEEX_SET_MODE There is no description though what this request does. I think the mode somehow maps to the bitrate, but I cannot find a table that tells me which mode maps to which bitrate for nb, wb and uwb codecs. And what does it mean when mode=any? Can someone explain me what the mode indicates? Best reg...

...decode a recoded sound encoded by speex, it has too much noise. The noise is "slightly" reduced if I set the quality to 10. How do I get rid of this noise? The code is as follows. For encoding . state = speex_encoder_init ( &speex_nb_mode ); tmp = 7; speex_encoder_ctl ( state, SPEEX_SET_MODE, &tmp); // set quality tmp = 10; speex_encoder_ctl ( state, SPEEX_SET_QUALITY, &tmp); // initialize bits speex_bits_init(&bits); while( 1 ) { // read FRAME_SIZE bytes from buffer // convert to short for ( int i = 0; i < FRAME_SIZE; i++) in[i] = o...

The first thing to know that setting quality from 0-10 is in fact a more user-friendly of setting the mode.
