Is this strictly for professional streams? I would assume so, all independant streams could be listed in the directory. Thoughts?

Since I've been the main contributor (so far, I hope others will add more), the list mostly reflects my own listening interests. There are a bunch of semi-pro streams, for example student or community stations, and a few that seem to be one-man internet-only streams, for example Brazillbient Lounge. So no, not strictly for professional streams. --Andrel 13:08, 26 Oct 2004 (PDT)


In the listening tests at [1] the following quote is found:

"Although Vorbis didn't perform well, almost getting under the big tie at second place, part of it can be credited to the fact that it was being tested at 22kHz. The severe lowpass at this bitrate seems to have introduced serious quality issues in the samples tested. One can hope Xiph enables 32kHz sampling for 32kbps, and further tunes such small bitrates."

Does anyone know if this has been done or if plans are underway to make Ogg Vorbis more dial-up online streaming friendly?


The aoTuV encoder ( ) has some advanced low bitrate tunings (quality modes -2 and -1) that support 44.1 kHz stereo output with bitrates as low as 32 kbps.

Open Question

Is it worth noting some Internet trivia, pertaining to the audio streaming of one of websites listed? I propose the following:

On November 7 1994, WXYC-FM became the first radio station in the world to offer a live Internet simulcast of an off-air signal.

The Computer Science department at Brown University was simulcasting WBRU-FM around '90 or '91. It was done with an FM radio plugged into the mic jack of a SPARCstation. The stream was in Sun's Au format. --Andrel 07:42, 9 September 2008 (PDT)
While this sounds like an important milestone (citation needed), it sounds as if they were re-transmitting, not simulcasting. Simulcasting (simultaneous broadcast) happens at the source. The CS event seems to be more of a proof-of-concept than a content distribution strategy. IMHO, it is more interesting in what the content provider believes to be appropriate audio distribution, since that is their business. In 1994, WXYC was the first radio station to decide to broadcast using the Internet, an activity that became a standard later. Today, WXYC uses Ogg/Vorbis for their broadcasts, perhaps another indicator of future standards.

Archived Streams

I removed this section, after having no response to this discussion paragraph. The listed shows: Quirks and Quarks, LUG Radio, News from Neptune were not originally streaming media, and so how can they be classified as archived streams? If this section is supposed to be for media archives of live events and live shows, then just about every Ogg Vorbis media file will be applicable. Unless I am mistaken about the purpose of this section, I suggest it is removed, since none of the list are streaming in the same sense of that the rest of the page means Vorbis Streams.
