Hello! Some time back, I added the Speex protocol to my version of VOCAL (www.vovida.org, VOIP tool). Recently, I also added PESQ (automated voice quality testing algorithm) to my tool and have been running some tests on a clean network. The source file is a woman reading some phrases meant to test various aspects of codecs... Speex has a respectable result of 3.67 Some other codecs I've

Hello! I'm about to try to integrate SPEEX into the VOCAL project. If anyone has any pointers as to the best way to do this, please let me know. After reading the speex api man page, I have a few questions: 1) To encode, it appears I need an array of floats. If I am playing wav files, what is the best way to turn these into something speex can encode? 2) Are there any commercially

It does significantly better with a different speaker (the male does better than the female), as well. I'm considering purchasing a commercial PESQ license and wrap the PESQ software in a server application. I could then allow other folks to run PESQ

How about if I sell you a copy of speex. Buy low, sell high seems like a good capitalist plan, and then you could feel good about using Speex! Ben -- Ben Greear

Hello! My company makes testing software that, among other things, can be used to generate file-system traffic. In order to better support Samba, I need to make a few changes to the way samba mounts file systems: 1) I need to be able to specify the local IP address for the socket connection. This will allow me to bind different mounts to different local interfaces. This information will

This portion of the RFC is gramatically incorrect and confusing: The RTP payload MUST be padded to provide an integer number of octets as the payload length. These padding bits MUST be all zero. This padding is only required for the last frame in the packet, and only to ensure the packet contents ends on an octet boundary. <p> -- Ben Greear <greearb@candelatech.com>

Hello! I recently started testing curl's tftp options, and found that it crashed when trying to upload files using tftp because it didn't handle OACK properly. So, I'm attempting to fix it. Now, I have an endless loop: The client (my hacked curl) sends TFTP write request with options, server responds with OACK (tsize, blksize) client sends data packet, block 0 BUT: server responds

Hello! I am trying to set up multi-link PPP using two T100P cards in one machine, and 1 T405P card (the 4-port one) in another machine. I have previously been able to get PPP working between the two T100P cards in separate machines.... The 4-port card seems to be my problem currently. I am trying to use the tor2 driver (from a fresh CVS download this morning). When I load the driver (or run

While working on adding support for local-binding, I found this piece of code in libmsrpc.c. Maybe I'm confused..but should that strcmp maybe be compared to != 0? /*change the server name in the server handle if necessary*/ if(srv && hnd->server && strcmp(hnd->server, srv) == 0) { SAFE_FREE(hnd->server); hnd->server = SMB_STRDUP(srv); }

Hello! I am trying to configure my PPP setup such that it only uses the first 4 channels on each T1. I see no obvious errors in /var/log/messages or when running the ztcfg, but I am able to still pass a full T1's worth of data over the PPP links. I would expect to only be able to send about 300kbps in this configuration. I am running the PPP link back-to-back on the same machine, by the

I'm trying to compile speex on an x86_64 (Opteron) platform, but since I want this resulting code to run on regular 32-bit x86, then I am passing the -m32 flag to gcc. It so happens that the libtool application included with my version of speex (1.0.3) does not handle this correctly and fails to create libraries. I fixed this by changing the configure script to just use 'libtool' and

Hi Marc, Thanks for your quick response. So if VAD is enabled then VBR will be enable although it's a special VBR. How about take out the VAD code from the VBR and remove the code else?

Hello, I'm try to run speex on some ARM processor. I'd like to cut away some speex features including VBR, ABR and preprocessor while still supporting VAD/DTX. But I've found some puzzles in the source code regarding VAD as below, 1) there are VAD related codes in the source file preprocess.c. Will VAD still work If I don't use the source file preprocess.c? 2)The speex manual

Dear Jean, Thank you so much for reply my message. I am sorry the function return 38 is speex_bits_write(). This function doesn't work on one of my computers. But after I add the function speex_preprocess(), it works well. I am wondering what is the possible reason? What the function speex_preprocess() does? Another problem I have now is when I enable dtx and vad with function

Hi there, I enable DTX and VAD in speex_encode to detect whether there is silence in voice data. But the same programme got different result on my computers. The function speex_encode always return 38 on one of my computers although it is silence. On all other computers the function speex_encode return 1 when it is silence. It means DTX and VAD doesn't work on particular OS or PC. Do anyone

Thanks for your reply. The platform is WindowsXP Professional with SP1. CPU is Celeron CPU 1.70GHz. Compiler is VC++ 6.0. I have enabled VAD and DTX . In this computer, speex_bits_write() still

Hello, We are in the process of debugging a voice quality issue for a client of ours that is a VoIP services provider. The client uses a softphone that runs on a pjsip stack. When placing a call using the softphone, it negotiates the use of G729 codec with the remote endpoint (ptime = 20ms). The endpoint transmits RTP packets with encoded G729 payload. VAD/DTX is enabled. We see that the last
