As others have said, 16kbps should do the trick. Keep in mind though that the quality of the sound will also depend on the sampling rate. MP3 will handle some hi...

I believe he said the outgoing stream was two 128k ISDN lines, which from my ISDN memory I remember as actually having a 112k throughput (the other channel being u...

Is that 24kbps AACPLUS a full 44.1kHz stereo signal with frequencies preserved up to at least 15kHz? (Just curious, not criticising.) As a datapoint, Vorbis aotuv b4 gives acceptable quality with q=-1.001 44.1kHz stereo at approximately 44kbps. -- Paul...

I've set up a 24kbps/MONO Ogg stream which is doing the same metadata updates that Lithium's stream is doing...it can be used to test this nasty winamp (and other clients) crashing thing that has popped up of late.... hopefully, 24kbps is low enough for modem listeners (especially ones who happen to have writte...

Hi, I want to encode audio at very low bitrates. however, vorbis_encode_init() does not allow me to set bitrates below 32kbps. How can i set 24kbps?

Hello, I've got two streams, one for broadband, one for dialup. Well, having had occation to use a dialup connection recently i checked the dialup stream. Although it was streaming what the broadband stream was, the audio quality was audibly worse. It didn't buffer, but it didn't sound as clear as the broadband stream. I used lame to encode the tracks to mp3 and used it's

...ny way to overcome this, either using icecast 1 or 2. I'm involved in a project called ACB radio interactive (http://interactive.acbradio.org) which consists of a number of DJ's from all over the world taking it in turn to use a common server. We currently broadcast using live365 at 16 or 24kbps in either mono or stereo, depending on the broadcaster's resources and preferences. However, we're looking to change to a model where we'd have 2 servers, one accepting connections at any rate (including broadband rates) and passing that off to a live365 server, whilst at the same time...

Yes it is 44.1kHz. However SBR is not the original, everything higher then 22.05kHz is recreated. Also Parametric Stereo recreates the Stereo experience. The actual audio data is simply a 24kbps AAC stream at 22050 mono. Also it is by no means perfect. The highs do have an artificial feel to them and a little echo. For what it is though most people don't really get annoyed by it and are quite pleased with the feel of it. -----Original Message----- From: icecast-bounces@xiph.org [ma...

hi everyone For my diploma work on streaming music, I'm looking into cost of handling a large amount of users. Somehow I couldnt find some experience on the net about how many concurrent streams a single box could handle using icecast (without encoding, just the streaming of pre-encoded mp3-files). Does anybody have some experience that I could include as a reference point ? Thanks !

I'm am currently using autuvb4 at q-2 mono 44100. This produces roughly 28 to 34kb/s. It's ok but I've heard AACPlus at 32kb/s stereo and it's definately better, unfortunately.

Hi all, must say I have found the help in this group very disapointing. Have mail numerous times for help with some (in hindsight) simple problems. yet no one (ok 1 person) has attempted to aid me. If this group was ONLY filled with novices and users I could accept this but I have seen members of the development team , and others who have insight into the workings of icecast comment on other

ok... topology. 486 with 10BaseT card hooking into 10/100 hub hooking into 10/100 switch hooking into cisco router combining two 128KbpsISDN lines into a consolidated 256kbps line. listening on my desktop machine is fine, also 10baseT into the same hub as the server. the bitrate on the mp3's is 128 (great for listening off the HD) whats a good bitrate to encode for streaming audio? At

...s very little in the way of resources. Your outgoing bandwidth will almost certainly be the limiting factor. Just divide your available bandwidth by the bitrate of your stream (& lop off about 5% of that number for overhead & a safety margin) . Example: a T1 line = 1.54 mbps = 1540 kbps / 24kbps (stream bitrate) = 64 streams So a T-1 line can support 64 24kbps streams (in theory).

...egabytes of RAM), plus whatever your operating system needs for overhead, plus 1.5MB for the server's base requirements. Don't set the listener count higher than you need, it just screws things up. * Enough bandwidth to run the server. If you want to broadcast to 100 listeners at 24kbps, you'll need about 24kbps*100 = 2,400kbps = 2.4Mbps of bandwidth. That's about 2 T1 lines worth of bandwidth. Trying to push 100 128kbps listeners down your 768kbps cable modem isn't going to work :) <p>Is it the same rules for Icecast?? Thank you in advance. -- CHRIST...
