You can store up to 1000 server profiles. In LUCI Studio you then have the ability to choose between them. You will see a drop-down list with all currently defined profiles and a profile called ´New´ that
enables you to add a new profile and ´Delete´ that will delete the currently selected profile. If you have only 1 profile you can not delete that.
Each profile can use a different output format. If you choose Output format “New project” this profile will use the general output format as set before in the ‘New project” page. Look at the ‘New project’ setup for explanation about the different available formats.


The name of your radio server and port-number. In the common form: ´servername:portnr´ for instance ´´. If you do not fill in the :portnr LUCI will use the default port, which is 5004.

If you use LUCI Studio only as a server do not fill in the ip-address. But fill in :5004 for instance(including the colon). It will still send a stream back when it receives a valid stream.
Besides using a URL you can also fill in an ip-address. For ipv4 for instance:
For ipv6 you should put the address between square brackets like this: [2001:980:4937:1:1483:291:1351:a206] . You can of course also use a URL with ipv6.


Fill in the user-name you use to login at your server. For the RTP protocol this is not used.


Fill in the password belonging to your user name. This password can also be used in a simple RTP authentication.


Shoutcast, Icecast, Multicast Src , Multicast Rcv, RTP, UDP, SIP, Audio/Video via RTP
LUCI Studio’s use of the UDP and RTP protocol is explained extensively in the server installation guide. We advice to use RTP on port 5010.


For this protocol you can use the following conventions for the different fields.

  • Server: user@URL:port
    user Is the one who you want to call. URL:port Is the sip server and port to logon or REGISTER to.
  • Server: user
    user Is the one who you want to call. The default sip server settings from the SIP page are used.
  • Serverautoanswer
    If you want LUCI Studio to auto-answer
  • Serverwaitforcall
    If you want LUCI Studio to only wait for a call and manual pick-up. Pick up a call by pressing the MIC-button.

Some examples:

  • “502@ means you want to call user 502 at the sip server’s ip-address on sip-port 5062
  • “” means you call user echo at on sip-port 5060 (5060 is the default when no port has been specified). Btw, this address actually works, but only with G711 codecs.

User and Password are YOUR credentials when you want to logon or REGISTER to a sip-server. When you do NOT specify a user, LUCI will not try to REGISTER to the sip-server. Tick Default user when you want to use the sip server settings from the SIP page.

Multicast Src


  • IP-address:port , example:
Multicast Rcv


  • IP-address:port , example: or
  • sourceIP,multicastIP:port for Source Specific Multicast , example:,

With Multicast Rcv protocol you can also add a fail-over Server where LUCI Studio can connect to when the original stream stops. According to conditions defined in the Options page in Setup. For an
explanation of the settings, see the Options page.

Extra audio delay

Here you can set an extra audio delay of 0 to 10.000 ms ( 10 seconds) for different protocols:
Multicast Src: extra delay before transmitting.
Multicast Rcv: extra delay at local audio output.
All other protocols: extra delay before transmitting.

Use global RTP/UDP settings

You can have different RTP/UDP settings per station or you can use the global RTP/UDP settings set with the RTP/UDP page. For an explanation of the settings, see the RTP/UDP page.


If you have chosen the shoutcast or icecast protocol you will see another feature list, as can be seen on the left. Some features are removed, others are added:


The mount-name, for Icecast servers.

Stream name

The name of your radio-station.
