Can anyone tell me why the size of st is defined as: st = (EncState*)speex_alloc(sizeof(EncState)+8000*sizeof(float)); Reference: nb_encode_init function. Specifically, I would like to know why 8000 floats are allocated? Thanks and regards, Vinay -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.xiph.or...

...e see my code (Delphi) and say me please WHat I am do not right. Or please send me correct compiled DLL and example of correct using SPEEX_MODEID_WB and SPEEX_MODEID_UWB , denoise, and other effects. How I can set MONO mode in decode? My Code: smpRt:=32000; n:=10; encbits: TSpeexBits; encstate: Pointer; encframe: integer; decbits: TSpeexBits; decstate: Pointer; decframe: integer; buffEnc: array of single; buffDec: array of single; encstate := speex_encoder_init(speex_lib_get_mode(SPEEX_MODEID_WB)); speex_encoder_ctl(encstate,SPEEX_SET_SAMPLING_RATE,@smpRt); speex_e...

...with the 'dtx_enable' flag in it, so the decoder on the other end knows it's in dtx mode? (and SPEEX_GET_DTX_STATUS returns 1) At the moment, I can hack around it by doing something like: if (VAD for prev frame && ! VAD for this frame) { iArg = 0; speex_encoder_ctl(m_esEncState,SPEEX_SET_VBR, &iArg); speex_encoder_ctl(m_esEncState,SPEEX_SET_QUALITY, &iArg); SBEncState *sbe = static_cast<SBEncState *>(m_esEncState); EncState *es = static_cast<EncState *>(sbe->st_low); es->dtx_count = 1; } (in wideband) .. which forces speex to send...

Hi, I'm trying a quick port of this terrific codec to uClinux, a Linux-derivate for mmu-less systems. I'm particulary interested in the alloc()'s the library does, and it's stack usage. In nb_celp.c I found two lines of code doing memory allocation : nb_celp.c: st = (EncState*)speex_alloc(sizeof(EncState)+8000*sizeof(float)); nb_celp.c: st = (DecState*)speex_alloc(sizeof(DecState)+4000*sizeof(float)); Where do these magic numbers 8000 and 4000 come from ? If I decrease those to 4000 and 2000, my test app still works (just lucky ?). Is there a way to know what the min...

Hi I am currently trying to port speex v1.1.6 to a microcontroller with very limited memory (<64Kbyte RAM). what I found when initialising the encoder, a chunk of 32Kb was attempted to be alloced, which failed: src/nb_celp.c: void *nb_encoder_init(const SpeexMode *m) { /* snip */ st = (EncState*)speex_alloc(sizeof(EncState)+8000*sizeof(spx_sig_t)); /* snip */ } same goes for the decoder: void *nb_decoder_init(const SpeexMode *m) { /* snip */ st = (DecState *)speex_alloc(sizeof(DecState)+4000*sizeof(spx_sig_t)); /* snip */ } I tried to reduce the stacksize from 8000/4000 to...

...uishing persistent and scratch storage. To do this, I added a speex_alloc_scratch routine, which uses a different memory block than speex_alloc. This does force a change to nb_encoder_init, etc. At the moment, the code looks like this: #if defined(VAR_ARRAYS) || defined (USE_ALLOCA) st = (EncState*)speex_alloc(sizeof(EncState)); if (!st) return NULL; st->stack = NULL; #elif defined(SCRATCH_ALLOC) st = (EncState*)speex_alloc(sizeof(EncState)); if (!st) return NULL; st->stack = (char*)speex_alloc_scratch(SPEEXENC_SCRATCH_STACK_SIZE); #else st = (EncState*)sp...

hi, I am using speex1.2beta2 on a TI 54x on narrow band I have been trying to get speex to work for a while now, and it's been a real teeter-totter ride. For a long time I noticed that I will get a project to work and then without changing any code and programming it to an eprom/flash the project will not work. It turns out it was a value called innov_save. I found this bugger by zero

Hi there. I am having a little trouble understanding the frame sizes chosen by the codec. testenc_uwb.c from the speex-1.0 source distribution has a framesize of 640 hardcoded and makes use of this value exclusively. However, a mode query on the actual codec returns 320 as a framesize for this mode. int tmp; speex_mode_query(&speex_uwb_mode, SPEEX_MODE_FRAME_SIZE, &tmp);

...++; j++; } while ((inBufpos % 160 != 0) && (inBufpos != (inlen/2))); //fill the rest with null if (inBufpos == (inlen/2)) for (j=(inBufpos%160); j<160; j++) input[j] = 0; speex_bits_reset(&bits); speex_encode(encstate, input, &bits); /*Copy the bits to an array of char that can be written*/ speex_bits_write(&bits, cbits, MAX_FRAME_BYTES); for (j=0; j<62; j++) { outBuf[outBufpos] = cbits[j]; outBufpos++; } } whil...

I am trying to implement a relatively high number of encoders (24/32) on a single DSP and would like to minimize the memory requirements. Has anyone optimized the persistent EncState memory allocation for multiple channels. The default C64x fixed point implementation allocates 5280 bytes of persistent memory per encoder. I'm willing to restrict my settings to complexity 1, quality 3. It looks like I can share the st->window, lagWindow, bw_lpc1, bw_lpc2, variables whic...

...innov_save = st->innov_save+offset; It means that the innov variable gets copied *unless* st->innov_save (notice is a field of the encoder struct). So the problem is that this field is probably not set to NULL. Normally, this is automatically set to zero when the init function does: st = (EncState*)speex_alloc(sizeof(EncState)); Is it possible that you did an override of speex_alloc and replaced it by malloc() instead of calloc() as I'm using? That would explain the garbage you're getting and it may actually explain other bugs you've had. Jean-Marc > I commented innov save...
