similar to: Integrating speex with VideoNet application: Constantbackground noise

Hi, I've changed the m_waveFormatEx.wBitsPerSample 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? Regards, Carine ----- Original Message ---- From: John Miles

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. Carine ----- Original Message ---- From: John Miles <jmiles@pop.net> To: carineliang@yahoo.com.sg; speex-dev@xiph.org Sent: Thursday,

Hi, I'm still unable to get rid of the background noise though I've changed the PCM samples to 16 bit. I'm began to wonder if I can just take the PCM samples and encode them. What my application tries to do is to record the voice from a microphone, encode it, send it via the socket to a peer, decode at the peer's side and play the voice. My application works fine without the

Hi Jean-Marc, Thanks. I've got the code for sampleenc and sampledec. But I didn't know how to verify whether the decoded file is correct. So I tried to analyse the decoded output and compile with my input. Test case: PCM samples, 8 bit, 8000 samples per sec. When I pulled all my input to 0s, after encode and decode, the output fluctuates around -0.12 to 0.2 (in float), so when finally

The absolute values may be different 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,

Hi Jean-Marc, I finally make it work! Thanks for telling me that the algo will not work for 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! Thanks a million, Carine

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

Dear Peter, I am running your g.test() with the william's correction but I have a question about the input numbers. These are my data: "Our data are consistent with those obtained using microarray comparative genome hybridization in that we found significantly fewer variants per Mb on the X compared to the autosomal chromosomes (152 versus 336 respectively, G = 93.4, P < 2e-16, df =

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

Hi, I am using the speex 1.0.4 library from Windows. I have posted my problem before but didn't get a solution. I am doing an VOIP project in which i am recording sound and streaming it to the peer. I wanted to encode and decode wav files that brought me to this site. I am recording sound in the following format:- m_WaveFormatEx.wFormatTag = WAVE_FORMAT_PCM;

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

The connection doesn't work, and with "dmesg" I see the following message, repeated every time I try: [26937.531511] CIFS VFS: RFC1001 size 39 bigger than SMB for Mid=4 [26937.531580] Bad SMB: : dump of 48 bytes of data at 0xffff880052832380 [26937.531615] 00000027 424d53ff 00000074 00018800

Hi, I'm experiencing weird problems while testing speex (I want to test the echo canceller first) on PDA with WM5 version pocket PC 2005. Here is the strange scenario: 1-> App running without being linked with speex -> no problem 2-> App running while being linked with speex -> crash at always the same place. NO ACCESS TO

Hi, here is a practical problem we would like to solve. In a pneumatic post the acceleration of the capsule is measured and plotted over time. From the graph achieved we would like to derive some kind of statistic value that describes the stress the capsule, or what is in it, is exhibited to. The amount of stress introduced to the capsule will probably depend on two things, the maximum
