similar to: g729 quality at GSM bitrates

I'm a bit confused about VBR with Opus. I see that the default is VBR, but I don't see any way to specify a quality setting. I can set a target bitrate, but that's definitely not what I want; I want a constant quality level, like "-q" in oggenc, and for the encoder to select bitrates based on the desired quality. For example, for playback through earbuds or laptop

Hello all, I've started implementing iLBC on some of the ATAs we have floating around clients' homes, but I'm coming against this error message with most of them: codec_ilbc.c: Huh? An ilbc frame that isn't a multiple of 50 bytes long from RTP (38)? The ATAs in question are various Grandstream models - the HT486 being the predominant one. Looking at the list archives, it's

Folks! We have purchased G729 and have been testing the codec on mUltiple Gateways. Here is what we have found. Here is the config I have used: ------------------------------- Asterisk Server On Dual Pentium Xeons with 6GB of RAM, running on Fedora Core 2 User1 is in USA on Broadband Cable User2 is in India on 64Kbps ISDN Line User1 using SIPURA SPA 2000 user2 using Xten professsional(X-pro)

I have managed to get TF2 working at an acceptable framerate under Wine. However 3 problems arise when playing it. When I run the game, it always sets my texture detail level to "Low" when I can run at "High" or "Very High" with very little performance loss, but no matter what I do, whenever I exit and restart the game, it reverts the texture detail level back to

Dears; I do not know if any had experience in using speex or ilbc with IAX and got good results, because I am facing a problem with GSM. I am facing a noise problem when I am using GSM with IAX trunk as following: IP Phone (G711) ---> Local Asterisk Box ---> IAX Trunk using GSM codec ---> Remote Asterisk Box ---> Digium Card (FXO) to terminate the call to the destination While no

Dear all. I recently subscribed to a VoIP provider through IAX. The require to connect with either G729 or GSM, I chose G729 based on their recommendation. The service works very well, however ... people mentions how distorted our voice sounds. We have plenty of bandwidth available so I don't think it comes from our side. What it means is that it comes from two things: 1-G729 gives bad

Hi Friends, I want to implement VOIP PBX service in my office. I have 10 computers and a server. All computers are Pentium IV processors with 512 MB RAM. All employee computers have Windows 2000 Professional OS and Server computer Windows 2000 Professional and Fedora Core 5 Linux OS. I have a VOIP phone and have registered with VoIP service provider. Now, I want to implement VOIP PBX facility to

Does G.729 provide better voice quality than GSM? (a question for people who have tried both) --J. -------------- next part -------------- A non-text attachment was scrubbed...

Hi all, When encoding narrowband with speexenc I notice the bitrate is the same for qualities 3 / 4, 5 / 6, and 7 / 8 (8000, 11000, and 15000 respectively). I didn't test this on prior versions of the encoder so I'm not sure if this is something new, but am curious if there is a difference between the above respective settings (does quality 4 yield better results on narrowband than

Hi all, I used vorbis several years ago because of its freeness and VBR, but after playing ha.org and getting an mp3-capable discman, I switched to APS and API mp3 encoding. Now, I am liking musepack a lot, but the flexibility is more "there" for the vorbis format, including players, tagging comments (lyrics in the comments - killer idea!), etc.... However, I am a bit worried

Greetings list, We have an issue with call quality at 2 sites where the users (4 Elmeg IP290s at one site, 2 SPA942s at the other) do not have an asterisk box on-site. Each site has an 8mb down/448k up ADSL connection and the phones connect via SIP to an asterisk box in a datacentre using g729. The asterisk box in the datacentre connects to our other asterisk boxes providing pstn connectivity

In our experience, the total cost of softphones(money, reduced sound quality and lower reliability) in a large call center environment is actually greater over time than the cost of a channelbank and cheap analog headphones. We've tried 2 softphones, 2 kinds of SIP VOIP hardphones, 2 kinds of SIP analog adapters and we've tried channelbanks over the last 3 years. Right now we are half done

Hi all, I hope someone could enlighten me... How could I resolve the fact that the volume controls of all the headphones I try on CentOS 7 are not working, they are OK on CentOS 6 but impossible to make them work on my Thinkpad Laptop with an iPhone headphones or a Marshal Monitor plugged with a jack connector... Those 2 headphones work correctly in CentOS 6... What could I do to get the same

Hello. First of all, thanx for that great codec. I would encode all my music with Ogg Vorbis in the future, if it hadn't been for some samples I encoded for test purposes: Everything was great as long a I used "natural" sounds/music, but certain pieces of synthesized music (specially techno) contained very audible artifacts even at high bitrates. So I just went on using mp3 for

After installing CentOS 5.2 on my Dell inspiron 1525 laptop, the sound was inactive, I then installed Alsa-Driver, Alsa-utils, Alsa-plugins and Alsa-libs the ATrpms site. The speakers then work fine, but when I plug in headphones, the sound begins to fade out and eventually becomes completely quiet. I have checked the Volume Manager and nothing is muted including the Headphones volume, when I

hi flac list! I'm not sure if this question can be asked here, but here you go (it's a question for audiophiles only): I encode CDDA tracks to FLAC and play them on my Pocket PC (PDA). I'm looking for a high quality headphone to connect to my Pocket PC, but it must be an in-ear one but not like these: http://s7d1.scene7.com/is/image/vanns/770045336?$medium_item$ So no plastic things

Logitech H540 headphones were working fine. Suddenly stopped. Sound Preferences says they are disabled but gives no hints on how to enable them, or how they became disabled. Tried rebooting, unplugging them, etc. Anyone know what is going on? This motherboard doesn't have onboard sound, this USB is my only option. And GNOME simply isn't usable for me, I used GNOME for years but
