I'd just like to say thanks to Giles who was kind enough to reply to an email of mine with detailed instructions which I am now posting here:
From Giles:
Broadwave is simple to use and produces 2 audio streams for dialup and
broadband. It also gives you the option to choose the bitrate(s) for
the 2 streams from dropdown boxes. Broadwave is free to use if you
have a link to their site and is developed right here in Australia. It
is also resource friendly (i have a jriver, win xp/iis and broadwave
setup for my Random Radio running 24/7 on a PIII 900 with 256mb RAM
!!)
You can get VAC at:
http://software.muzychenko.net/eng/vac.htmlOnce you have installed VAC run the VAC control panel and create 1
audio channel and set the volume to disabled. The reason for this is
if you also have jriver playing music to the on-board soundcard and
maybe even have a remote, if you change the volume up or down it will
not affect the audio being streamed to the net via the VAC and
broadwave.
Now configure the jriver default soundcard (or create a new zone and
change the default soundcard for that zone) to be VAC not the on-board
sound card or wave-mapper etc.
Create a DynDNS (dynamic dns) domain name. DynDNS is a free service.
Install and configure DynDNS.Use the software as your router will
update to often and your domain name will be blacklisted and rendered
unusable.
Install Broadwave and configure it to use port 81 (we will use port 80
for IIS) and change the address to that of your dynamic dns domain
name. Finally select the software to start automatically and choose
the 2 bitrates of you audio streams. My suggestion would be to setup
the dial up for internet use and broadband bitrate for use on your
LAN as it supports much higher bitrates. I have my internet stream set
at 24kbps and it is faultless even when being streamed by a 28.8k
modem. The sound quality is pretty good considering.
To make it sound like it does, i use the jriver volume leveling and
have tweaked the equalizer to provide more treble and a little bass to
cope with the sound being flattened by being compressed into the
24kbps stream.
Now drag the jriver shortcut into your startup folder and configure
jriver to startup with the display view and to start playing current
playlist.
Reboot. you should now be ready to stream to the net.
open the dyndns url you created and add ":81" to the end to open the
broadwave links page on your server. click on either the dialup or
broadband links.
