similar to: streaming audio / low bitrates

Hello, how good is the quality with very low bitrates like 16kbps mono. 16 kbps files compressed with lame sound awful, realaudio is much better. Will vorbis sound as good as realaudio with low bitrates? How fast is vorbis (in comparison to lame).

Hi everyone. I did a rough recording of an instrumental (electric piano sound) & e-mailed it to a friend in Vorbis 11025 Hz / mono. I was seeking a bitrate in the range 8-16k/sec. The song is 2:55 in length. q=-1 happily achieved a 12.6k/sec bitrate. All file sizes I mention in this are for files without informational tags. And I hope this isn't interpreted as trying to plug my music or

Hi! We have a little problem. We have to get 4 channels through a Dual-ISDN Line (128k). MP3 sounds awful (tested with lame 24k). Real sounds good, but I cannot encode 4 mono streams from a 4 channel soundcard, only 2 stereo streams. So I tested Vorbis. I encoded a 22050Hz mono file with -b 112, but this has a average bitrate of 59kbps. the 44100 mono file is 94kbps in average and the stereo

dear vorbis developers, it would be very useful, if oggenc would support constant low-bandwith bitrates for testing. something from 20kbps to 44kbps, so anyone could test streaming over modem and isdn. audio quality doesn't matter. mörk --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to

In testing, I have found that both MP3 and RealAudio 3(!) are much better sounding at bitrates from 8 to 40-something kbps than Ogg Vorbis. This definatly needs drastic improvents and I know that 1.1 will be focusing on improvements in those areas but that seems pretty far off(a few months minimum) which leaves low-bitrate streams sounding pretty bad. --- >8 ---- List archives:

At SxSW I ran into the Xiph gang and someone said something in passing that the new version of Ogg Vorbis would have much-improved low-bitrate quality. Wondering - true? Details? ETA? At CD Baby all lo-fi soundclips are still in the SFERA format*. At 20k bitrates, they sound GREAT which is why I stick with it, but I'd much rather switch them ALL over to OGG if there was a way to make

Hi, Currently streaming ogg isn't practical in this situation. That was one of the first things i checked into. WHen i looked i didn't see a streamer that did both ogg and mp3. Thanks.

Hello Thomas, You are correct - the application is basically for secure remote access to ham CW (morse code) station. I believe the solution will be based on low bit rate MP3 streaming for receiver side (MP3 allows use with existing CODEC in client side, which could include Win CE or Linux palmtop type form factor, and the audio source would just be "voice grade" material on a mono,

This is another reason aacPlus is an advantage. It is supported using Orban Opticodec-PC Streaming Encoder, Icecast2 Servers and Winamp. http://www.orban.com/orban/products/stream/1010_overview.html Icecast2 Eval Stream here: http://www.orban.com/orban/products/stream/orban_eval_ice.pls -greg.

This doesn't specifically answer your question, but is it possible for you to use an ogg stream? I've been running a stream using a 48Kbps ogg (i'm sure I could push it lower too...) and it sounds to me and other people pretty much just as "nice" as a 128Kbps mp3. We can't notice it being audibly worse. -Daniel On 12/30/05, Dave <dmehler26@woh.rr.com> wrote: >

Ok, not bad -be sure to rm config.cache if ices has already been compiled.

Hi, (this is my first post here) A previous thread, starting Date: Tue 19 Nov 2002 - 06:09:56 EST "[vorbis] need speech and music in one" http://www.xiph.org/archives/vorbis/200211/0142.html expressed needs similar to mine, to encode a lengthy speech at low bitrate. I did some tests initially in September then concluded in December, and I was surprised to find Vorbis to be the best

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

hi, i´m looking for an implementation of really low bitrates (16k per channel or less) with ogg vorbis. ome backround informations: i work on a portable device for streaming over the air with hard storage limits, so i like to reduce the filesize without loosing all quality. any ideas or suggestions? thanks oliver --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project

I've just done some rudimentary testing to see how Vorbis degrades at absurdly low bitrates without downsampling. In summary, don't hope for anything decent below -q 0 for now. I tried oggenc -b <bitrate> -M <bitrate> for the below and a few in between: 24k - spectral energy "floor" captured decently, but many pure-tone blips (think old computer movie sound effects)

Hi, I'm really happy Ogg Vorbis 1.0 is out. I have some questions though: - what are the valid bitrates / channel / sample rate combinations? experimenting I find that at 22050 Hz I can not use 24 kb/s stereo, and at 16000 Hz I cannot use 18 kb/s stereo. Is there a table of valid bitrate / sample rate combinations? <p>- is there documentation for the encoding API? looking at the

I think when the real-time cbr encoding issues are sorted Vorbis (this is my experience with oddcast dsp, winamp and icecast 2 win32, big cpu hog) will start gaining more ground, also I think it will also gain more ground when it starts getting implemented into the more mainstream software and hardware products. For the most part vbr mp3 (btw, provide mp3's for downloads as vbr.. Better

ICecast i capable of sorts of streams, that is not your problem. Your stream source client (DSP) is the part who must be capable of streaming the format you want. For AAC use oddcast DSP www.oddsock.org capabale of AAC, LAME Mp3, and OGG (Free to use) very good at OGG specially with the vorbis 1.1 aoTuVb3 DLLs For AAC Plus (HE_AAC) use Orban opticodec for PC (witch is capable of every bitrate
