search for: 12kbps

...CE. I have a few questions here: 1. When I choose VBR mode, the codec seems to choose the bitrate on its own. However, that seems to be an issue on mobile devices. In some cases, when I configure the bitrate to say 20kbps, I see that the outgoing codec bitrate at runtime is sometimes far less (11-12kbps even). That leads to a lower received audio quality. When I choose CBR mode however, the outgoing bitrate is fixed at 20kbps and produces better audio quality. Is there a way to bias the VBR mode to use a value closer to the configured target bitrate or fix this low bitrate issue in any other way?...

...y doing the job we had expected. It's the long standing wish that everyone wants... More for less. We are just seeking a bit of magic that just may not be there. Ideally finding a codec that can perform tollerably/intelligibly at 2-4Kbps. And still perform quite well for complex speech at 10-12kbps. Just keeping my eyes (ears) out for something that I have never considered before. I really appreaciate the time you've taken to reply, Thanks.

Hi, I appologise for the bad ettiquite of this, but I have tried looking for some HTB examples that would help me, and am having trouble understanding how the tc filters should work, but I can''t figure out why this isn''t working. I''ve written this script, based upon the ultimate traffic shaper at LARTC, to try and shape for me and my 3 housemates. The idea being to

...t; ) ; class ( <$ssh> ) if tcp_dport == 8080 ; /*Changed port from 22 to 8080 */ class ( <$otro> ) if 1 ; htb () { class ( rate UPRATE, ceil UPRATE ) { $emule = class ( prio 8, rate 6kBps, ceil P2P ) { sfq; } ; $smtp = class ( prio 1, rate 6kBps, ceil 12kBps ) { sfq; } ; $ssh = class ( prio 0, rate 3kBps, ceil 5kBps) { sfq; } ; $otro = class ( prio 1, rate 8kBps, ceil UPRATE ) { sfq; } ; } } } } Also, given the priorities it''s expected to let me surf the web or chat in msn messenger rather than take my whole bandw...

Hi! Useful advice, thanks! Actually I had been using foobar2000 to recode, because it just makes it so easy to convert multiple files while keeping the metadata (I confess, I'm a "tagger"). But it's easy to miss some encoder option when being presented some default suggestions in a dialog form... Apart form that I always had the impression that Opus could be quite smart

...(raw[33].b >> 4) & 1 ; class ( <$otro> ) if 1 ; class ( <$p2p> ) ; htb () { class ( rate UPRATE, ceil UPRATE ) { $smtp = class ( prio 1, rate 6kBps, ceil 12kBps ) { sfq; } ; $ssh = class ( prio 0, rate 3kBps, ceil 5kBps ) { sfq; } ; $ack = class ( prio 2, rate 8kBps, ceil 15kBps ) { sfq; } ; $otro = class ( prio 1, rate 8kBps, ceil UPRATE ) { sfq; }...

Hi! So here is what I got with different encoder settings; still not sure what the "best" setting is. 6kbps seems to add distortions, so I tried 12kbps. MP3-Original: LAME 3.99r, 120kbps, 44100Hz, Stereo, VBR V5 (22:23, 19.8MB) Opus (--raw-rate 44100 --bitrate 56 --vbr --comp 5): (44:45?, 23.4MB): Broken Opus (--bitrate 56 --vbr --comp 5 --ignorelength - %d): (22:23, 12.1 MB, 74kbps) Opus (--bitrate 6 --vbr --comp 10 --ignorelength - %d): (1MB, 6k...

Hi! I have some MP3 audio material which is basically speech with some background noises, essentially > 120Hz and < 5kHz. I had the idea to reduce the file size by recoding the material to Opus at 56kbps. Unfortunately the result is a file sampled at 48kHz much larger than the original. I hope you agree that it does not make sense to create a file larger than the original (MP3). Of course

Hello, First of all, I already contacted Martin Devera, the developer of HTB, and he told me to search for help on this mailinglist, thus I am describing my problems here now... I am kind of seriously annoyed by QoS as I have been trying for over 3 years to get it working properly - first I did not understand how it works, then it seemed not to work, then it was working perfectly for half a

Hi all :) I''m new to this list, as I''m new too to traffic shaping ;) I''ve set up an FTP server in my ADSL line and I wanted it to serve as fast as possible as long as I don''t use my outgoing ADSL bandwidth, and I''m currently using HTB for that (succesfully, I must add). The problem is (when the FTP server is serving higher than its
