...hen I commented out the encode and decode, I am able to hear the recorded sound without no background noise. Is my decoded output expected? Since I'm dealing with a 8 bit sample, am I right to say that I will not have the "big/little endian" issue? What has gone wrong???

...ced the values after decode is very much different from the values of the original PCM samples. For cases when the PCM sample values are constant (because no one is speaking), the decoded values fluctuate too. These fluatuations are causing the background noise. Is my observation expected?

...t, send it via the socket to a peer, decode at the peer's side and play the voice. My application works fine without the codec but I need to achieve a lower data rate. Anyone has done that before? Is there anyone who's deal with encoding and decoding PCM samples in windows? Please help.

...r 8-bit PCM. In fact I've tried using 16 bit PCM last time, but apparently there's a bug. The bug lies with the RecBuffer. The RecBuffer must be set to 320bytes instead of 160 bytes since every sample is now 16 bit. The compression is amazing, from 320 bytes to 38bytes!

...rSample for both record buffer and playSound buffer, changed my array from char to short and I'm still getting the same constant background noise. I notice that when I talk into the mike, I will get a slightly louder noise, can't hear any clear speech... Any idea what's wrong?

...ent for a variety of reasons; you can hardwire them all to 0 to see if your noise goes away. Make sure the values on the decompressed (PCM) side are little-endian (low byte first in memory), assuming you're working in Windows on x86. -- john RAD Game Tools -----Original Message----- From: Carine Liang [mailto:carineliang@yahoo.com.sg] Sent: Sunday, November 05, 2006 8:38 PM To: John Miles; speex-dev@xiph.org Subject: Re: [Speex-dev] Integrating speex with VideoNet application: Constantbackground noise Hi John, I noticed the values after decode is very much different from the v...

Hi John, Thanks for your reply. Yes, my output device is in 8-bit mode, same as my input mode. I'm actually working in char (8 bit) arrays. Is it necessary to work in signed short integers only? I changed all the short arrays in the example to char.

Should I have to include any total number (in this case Mb) minus the variants? g.test(rbind(c(152,(999848)),c(336,(999664))), correct = "williams") or g.test(rbind(c(152,336)), correct = "williams") ?

Hi, We are using your product openssh 2.3.0p1 and we should upgrade to openssh 3.7.1p1 mainly for better SSH2 support but also for the bug reported on <http://www.kb.cert.org/vuls/id/333628> Is this problem located on the server side or on the client side, or both? Regards, Carin Andersson Software Developer Ericsson AB

HI, Can I run a openssh 3.7.1p2 client against a openssh 2.3.0 server and vice versa when using SSH2? Regards, Carin Andersson Software Developer Ericsson AB

Hi, I have a question about the code for version openssh 3.7.1p1. In the file ssh.cc you address ssh_session2_setup in some way: channel_register_confirm(c->self, ssh_session2_setup); Do you address the function: static void ssh_session2_setup(int id, void * args) in the same file or is it something else you address? If it is that function please tell me why the ssh_session2_setup function

hello everybody in this great mailing list , i have some difficulties to follow my code . i solved some problems thanks to Carine Liang , but i still have one problem and i think it is fatal one. when i encode the voice data in a wav file it is decoded without any errors it gives me 84 bytes wav file size for 139 kbytes wav audio data .Naturally i wanted to return my file back to its normal state by decoding it i made up the...

Hi, I am developing a peer-to-peer video conference application which uses speex as a codec for the voice. I am new to speex, so please bear with me if I asked the obvious. After I added the encode and decode function to my MFC app, I heard a constant background noise, even when no one is speaking into the microphone. #define FRAME_SIZE 160 The application is coded in MFC C++. The record

Hi, I'm using R to treat a table (with a lot of missing values) with Rulefit. The matter is when I use the command rfmod. Actually, I don't know how to deal with the error message. I don't know were "true" or "false" is missing. Someone can help me? Thanks The following part is the script I used with the error at the end. platform = "windows" rfhome
