...*ptr) return (*((SpeexMode**)state))->enc_ctl(state, request, ptr); -> int sb_encoder_ctl(void *state, int request, void *ptr) ... case SPEEX_GET_SAMPLING_RATE: (*(int*)ptr)=st->sampling_rate; break; ... And st->sampling_rate is 2. I debugged some further and it seems: sb_encoder_init calls speex_decoder_ctl(st->st_low, SPEEX_GET_SAMPLING_RATE, &st->sampling_rate); to get the sampling rate. I think it should be speex_encoder_ctl (otherwise SBEncState * is interpreted as SBDecState *). Best regards, Chris --- >8 ---- List archives: http://www.xiph.org/archives/ Og...

Hi, No, it only happens with speex_wb_mode. But like I said, it is because in wideband mode, the function sb_encoder_init is called and this function initializes the sampling rate using speex_*de*coder_ctl instead of speex_*en*coder_ctl In narrowband mode, the sampling rate is just initialized to 8000 st->sampling_rate=8000; BTW, I saw that my email was added to an existing thread instead of creating a new thread....

Hi, Speex is getting close to beta4, which I'd like to be feature-complete (or as close as possible). That's why I'd like to ask if anyone here has needs for a feature that hasn't been implemented yet. If so, please let me know. For those interested, here's what's going to be in beta4. First, the VBR code has been greatly improved and now works good with wideband too.

Jean-Marc, I was wondering if you could add a check to ensure that memory is actually allocated during the nb_encoder_init and sb_encoder_init functions. We have been looking at using Speex on a DSP and noticed that if we didn't allocate a large enough heap space memory segment that the DSP would crash. I would recommend something like: if (!st->stack) fprintf(stderr,"ERROR could not allocate memory for stack");...

...the speex software, we found that the "speex_alloc" of the code did not check whether the memory was allocated and used it directly. Is there a security risk? Is there a solution for this?

Hello The st->zeta pointer isn't freed in the speex_preprocess_state_destroy() function of the preprocess.c file (alloced in line 167). It's in Speex 1.1.4 by the way. I'm trying to make the denoiser work with my application and has got reasonable noise reduction after applying the denoiser. I, however, haven't been able to find any information of what the purpose of
