Bad mistake. I'm sorry, I wrote this text to one developer
of MuSE and wanted to send parts of it to this list - time
for bed.
I would be very happy if already some developer are on
this list to support mixplayd.

Salve red_eagle,
ich finde den ansatz von mixplayd einen unabh=E4nigen D=E4mon
zu haben genau richtig. F=FCr einen Drucker gibt es ja auch einen,
der von allen Programmen, die etwas drucken wollen die Auftr=E4ge
entgegenimmt. Wieso nicht auch beim sound. Zumindest bei
Studio, Radio Anwendungen wird so ein Modul gebraucht.

Wie stellt man ein Entwicklerteam zusammen?
Wie kann ich Dir (oder doch Euch) helfen?
Ist so ein genereller D=E4mon mit unterst=FCzung von MuSE=20
zu erreichen?

Salve jaromil,

I like your project and Patriks vision of ROSS a Radio Open Software Syst=
em.
http://ross.sourceforge.net/

Last day I got in contact with the developer of Audacity, too.
http://audacity.sourceforge.net/

They agreed, that Vorbis Ogg become very fast, very populare in the
Open Source comunity "I expect that open source software will start adopt=
ing=20
Ogg codecs very quickly now" With this codec is it possible to use lower=20
bitrats. One topic on the developer mailing list is lossless editing.
To save time and original quality, unchanged parts of an ogg-file
should expored originaly. This would be nice for internetstreams, too.

Imangine one independent journalist is making recordings somewere
in the world. If data-transfere is expencive he would codect it in 32 Kbi=
t/s
Mono with Vorbis Ogg (sound still great!) if the station would cut it,
they should use Audacity with lossless editing.
The studio should use  lossless broadcasting to create an vorbis
ogg stream. Even listners to a 96KBit/s stream should get the original
32 Kbit/s without reconverting and blow-up.=20

So I see a need for a broadcast-mixing-engine that is open for
multiple sources and formates (wav, ogg, mp3). This engine shound
decode all and mix it - giving it to soundcard and a codec for an internt=
et
stream.
But if only one input-source is deliver on OGG-stream, this is send to th=
e
internet-stream direcly. Maybe switching would be hearable, because
the decoder is using > 20 ms. Than must be the delayed the direct stream
by > 20 ms before switching.

There programs without using a microphone (playlist, rebroadcast)
programs with using a microphone without automatisations
and program with timed automatisation.

So I see a need for >3 sort of broadcasting frontends,
but for all this "lossless directstream" would be important.=20

Whats your  ideas to this?
Would you welcome such an general broadcasting-mixing-engine?
Would you support it?
