Congrats Jean Marc, Just heard you got a new google assistant for the Ghost project!

Jean-Marc, So I saw in the latest code that the vad in the preprocessor is gone/going to be re-written. Is there a plan as far as this goes? Just wondering as the current one seems to work pretty well. Thanks!

Totally possible- this is the first time this has happened that I know of in many many hours of usage- On the other hand, this null check isn't in my code base and it was in nb_decode_lost, and nb_encode- so I figured it was just an oversight- Tom

Hi, So I got a crash on the following code: k1=SUBMODE(lpc_enh_k1); k2=SUBMODE(lpc_enh_k2); which in the newer codebase is: bw_lpc(SUBMODE(lpc_enh_k1), st->interp_qlpc, awk1, st->lpcSize); bw_lpc(SUBMODE(lpc_enh_k2), st->interp_qlpc, awk2, st->lpcSize); I am not sure if the newer code will have the same issue but the following check is

Hi Jean Marc & List, So I have been fiddling with the denoiser (again). While poking around I noticed that nb_preprocess is basically a counter that is mod-ded with 100 (the default), which causes Smin[] to be re- seeded with the value in Stmp[] (min of the previous adaptation period). Smin[] is then used to update the noise probability, which is (probably) less likely when adaptation

Hi everyone, I'm currently attempting to move Speex development over to Git. Because Git is distributed, I means that anyone would be able to do development and commits without having to get write access (and I can just pull from them). There are of course other advantages, like sane handling of branches and tags, local history, ... Now, one of the disadvantages is that Git currently

Jean Marc, I ran across the silence issue that results from the echo canceller producing "bad" floating point data. Unfortunately this hasn't been done in a way i can reproduce, but I found that calling reset didn't fix the silence, unless I also reset: st->PHI[i] st->Eh[i] st->Yh[i] So it may be good to add these to the reset function. I was using these in

That's definitely strange and I've never encountered that. Normally, the only way for _mm_load_ups to generate a segfault is for the input to be invalid memory, in which case the C version should crash too. I suspect the compiler (or something else) may be hiding the real problem. Can you get a debugger and see exactly what assembly statement is causing the crash and what the operands are?

Jean Marc, So the C99 array syntax is breaking some lesser compilers- is there a known max size for bark[]? Fiddling with latest svn again... Thanks!

There is a port to mingw, which is what many folks use now: http://repo.or.cz/w/git/mingw.git I haven't had a chance to fiddle with it yet so ymmv.

I'm not sure if this is due to the same problem, but I get the same clipping behavior when trying to use VAD+denoiser on a particular mic+speaker setup that has significant background noise (enough to really foul up the codec should the denoiser be turned off.) Leaving VAD off and transmitting continuously seems to be the only way to avoid this clipping. Another person I regularly

Jean Marc, Ok so I tested with the new code, same result- frame size= 160, filter length=160 ms/1280 samples, 8000 Hz diverged after 9564 calls/packets or 191 seconds. My system stays relatively in synch but is not perfect- difficult to measure if there is any clock drift, but it probably is. In order to make it break faster I use an open air usb microphone that is part of a logitech notebook

Current SVN compilation fails on Win32 (Intel C++ compiler 9.0): ..\..\libspeex\mdf.c(317): error: declaration may not appear after executable statement in block float adapt_rate; Just moved it up to the variable declaration block to solve it locally, but as it's not valid C, I thought I'd mention it ;) PS: With the same compiler, AGC fails horribly (Zlast goes to several

Hi Jean Marc and List, So I have started finally fiddling around with Ultra-wideband mode. It appears to be very similar in operation to Wide mode, except that when peering into the packet structure it looks like (and these are kind of questions as much as statements here): 1. update rate 0 is not used in UWB- only 1-4? 2. The total bits used for each UWB update rate seem to be as follows:

Jean Marc, I have been fiddling around with preprocess to try to get it sounding less metallic/underwater- so based on some things said recently, I have been first fiddling with mean_post and mean_prior to try to get them to do change the update rate, so that update_noise gets called at the right times. Haven't made it too deep into the code, but I have a few questions in speex_preprocess:

Jean Marc & list, Following up on this- there seems to be an issue with this calculation in mdf.c (Smooth echo energy estimate over time) Pey += Eh*Yh; Pyy += Yh*Yh; it goes too large for floating point, which seems to be caused by extremely large values in st->Rf[j], st->Yf[j] and smaller values in st->Eh[j], st->Yh[j]- things were relatively quiet

? is there any speex code in place that may help enable variable speed playback ? or perhaps another open source project has some code for this ? variable speed playback for voice messaging is an attractive feature, that would be well recieved for sure ! thx for any reply, Mark Tom Harper <tharper@sightspeed.com> wrote: At 12:35 PM 10/6/2004, Matthias Granberry wrote: >There is

Jean Marc, Thanks for the advice. The estimate update may come in handy. I have had some time to play with the adaptation time. I tried making the adaptation time 80, 160 and 320. It seemed like the smaller value was actually the best in my initial testing, but I need to test this against a more noisy setup than I have here. I am guessing that for vad a shorter adaptation time is probably
