Hello, With high microphone gain, I seem to have problem making the silence detection work. The speech detection works well for the rare dish sample, which has very low noise amplitudes in silence regions. However, if the microphone gain is set to really high, noise samples are taken as speech, as indicated by the non-zero return value from speex_encode() calls. I had VAD turned on.

I'm getting confused, what's the problem exactly? The AGC doesn't remove the DC or it adds one?

Howdy, I'm setting up several gluster 3.12 clusters running on CentOS 7 and have having issues with glusterd.log and glustershd.log both being filled with errors relating to null client errors and client-callback functions. They seem to be related to high CPU usage across the nodes although I don't have a way of confirming that (suggestions welcomed!). in

Hi We are working on a speaker phone system using PJSIP and Speex Speech processing API on an ARM platform. Currently we have spent about a month on getting the AEC to work properly and we have worked through the most common causes of problems (such as clock drift, synchronization problems and non-linearity's in echo path). Now we achieve ERLE of about 17 dB which tells me that the AEC is

On the cheap side, the ITX or even MicroATX machines work great. These are commodity items, so they tend to be far less expensive than custom solutions. Various manufacturers, but we've had very good success with any of the AOpen MicroATX boards and their slimline MicroATX case: Aluminum: http://usa.aopen.com/products/housing/A340-series.htm Steel:

Thanks Milind, Yes I?m hanging out for CentOS?s Storage / Gluster SIG to release the packages for 3.12.1, I can see the packages were built a week ago but they?re still not on the repo :( -- Sam > On 18 Sep 2017, at 9:57 pm, Milind Changire <mchangir at redhat.com> wrote: > > Sam, > You might want to give glusterfs-3.12.1 a try instead. > > > >> On Fri, Sep

Sam, You might want to give glusterfs-3.12.1 a try instead.

Hi all: I was analysising the speex code these days and learned much from it. Thank you so much! But I have a question about VAD: After preprocess(denoise and agc are off, vad is on),the input pcm speech was distorted seriously.The input speech include ten syllables(one~ ten), but the output speech lost one! Can you tell me why? Please see the attachment about input and output: (See attached

FYI - I've been testing the Gluster 3.12.1 packages with the help of the SIG maintainer and I can confirm that the logs are no longer being filled with NFS or null client errors after the upgrade. -- Sam McLeod @s_mcleod https://smcleod.net > On 18 Sep 2017, at 10:14 pm, Sam McLeod <mailinglists at smcleod.net> wrote: > > Thanks Milind, > > Yes I?m hanging out for

Hi all, i use speex preprocessor features in this way: =================================== #define NN 160 /* 20msec di audio */ ... int tbc=0,c,d,ret; spx_int16_t TEMP_Buffer[NN]; char DLECODE; /* Inizializza il preprocessore Speex se non inizializzato */ if(Modem->speex_pp_state == NULL) { Modem->speex_pp_state = speex_preprocess_state_init(NN,AUDIO_SAMPLERATE); }

This works really well for white noise reduction. However what I've noticed was the amplitudes of normal speech samples also get reduced. Is this something by design, or is there a way to automatically recover the original speech sample volumes ? <p>Thanks. <p>Tongbiao <p>-----Original Message----- From: Jean-Marc Valin [mailto:jean-marc.valin@hermes.usherb.ca] Sent:

Has anybody out there had luck with LDAP or similar to enable users to share a common logon database for Windows 2000 and Linux. Microsoft and Linux supposedly allow authentication using LDAP, Kerberos and alternative schemes to their native databases ie /etc/shadow/passwd and the SAM. Any help with this would be greatly appreciated. Steve S.

Hi, I'm trying to use a denoiser on a wince with a FIXED_POINT defined. Denoiser works OK - it removes the noise, but then it unacceptable hurts a voice. Here is a code that I use: #define TEST_DENOISE_SAMPLES 2000 void test_denoise() { FILE *fin; FILE *fout; spx_int32_t rate=0; int chan=1; int fmt=16; int denoise_enabled = 1; SpeexPreprocessState *preprocess;

Hi! I'm using the newest (beta2) speex library on PocketPC (Windows powered) and experiencing some problems with noise suppression preprocessor turned on while encoding 44kHz files. You can hear the example here: http://szalik.net/speex (this is a 44kHz, 16, mono file encoded in UWB mode) I tried using speex cross-compiled with gcc (fixed point + arm4 asm) and VS (just fixed point) and it

Isn't this a typcial situation when the is_stmt field in the DWARF line table should be used? If we set is_stmt=0 for the instruction loading the constant, then a debugger can choose not to stop on that instruction when doing "step" on source level. That way we can keep the original source location for a ConstantSDNode, but also telling the debugger that this isn't a recommended

I have been having issues with my Centos 7 Samba4 setup. Not sure if it is related to a recent samba package/version update, but things are no longer very stable. While looking at the logs, I see the following message on my BDC.

Hi, I have been using Centos since 3.0. I have been upgrading regularly without any major problem. 4.1 to 4.2 has been a total disaster. I ran yum update, it went through and a couple of hours later I rebooted and X froze with the screen just being just fuzz [regular rectangles, orange, green...] and the keyboard froze. Could not do a alt-ctrl-backspace, nor a Alt-F1-6 nor Alt-Ctrl-Del. I

Hello! I tried quite a few things before I could reach out to the community. The problem I am facing is that I am unable to run SPEEX in fixed point at WB 15ms or 20ms frameSize for some files. I tried using rc1.1/1.2/1.3 releases and all exhibit the same issue. I tried enabling the debug option during configuration step: ./configure –enable-fixed-point-debug; but this gives bit exact
