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

Hii All, VLAN is create in manageable switch, like Cisco Catalyst and other vlan cap= able switch. eac port in that switch can be assigned in different VLAN. so,= that switch capable to insert 802_1q to each incoming frame (Please correc= t if its wrong, i just newbie in VLAN).I want build VLAN but i don't have v= lan capable switch. Is possible to create a vlan capable switch using switc=

Hello all, i would like to build a setup to generate VLAN frames (respecting the IEEE 802.1Q standard) for testing purpose. How to configure a Linux bridge for it to become a VLAN switch? Is it possible? What user tool to use for that? brctl? Regards, Louis

Hello, I'd like to change some network variables (bandwidth, delay, packet loss) to measure how speex behaves in certain conditions. Do you recommend any tools you may use in speex development? It seems NIST Net isn't maintained anymore. I've found dummynet, looks interesting, but any hints you guys may have would be most welcome... Thanks, -- Adriano

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); }

Ok, I figured it out. :) This seems to work: 1) Call speex_bits_read_from() once, specifying the location in memory of the compressed data, and the total length of that data. 2) Keep calling speex_decode() until speex_bits_remaining() returns 0. Then you don't have to keep track of the # of frames per packet, or the size of each compressed frame. It's done magically by the codec.

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

Hello! I'm working on adding VAD (silence suppression) to my branch of VOCAL. I've read through the Speex docs and see mentions of VAD/DTX, but I am not sure quite how to use it. For instance, on the transmitter side..do I need to detect the silence somehow and bypass speex encoding, or can speex tell me that the packet is all silent and should not be transmitted as part of it's

Using the same pktgen script (i.e with clone=0) I see that a veth-->bridge-->veth configuration gives about 400K PPS forwarding performance where
