Linux Limiter for SC / calendar.xml 3:30h repeat events

RpK · 16th January 2015, 08:20

#1 Does someone use a sound limiter in conjunction with shoutcast? problem: when the live dj try too push the volume then there are sometimes "scratches" audible

#2 could someone give me a tip for 3:30h repeat events? im using diz right now:

code:
 <event type="playlist">

   <playlist loopatend="0" shuffle="0" priority="20">rampage</playlist>

   <calendar starttime="01:00:00" duration="00:05:00" timeoffset="03:30:00" repeat="128"/>

 </event>

but it does everything except of this what i want.. ^^

cheers fam

Sorry, but if a DJ can't hold his volume to a "normal" level then you should give him a instruction for that. If the DJ can't hold it again is it really bad DJ and you should think about to kick him/her from the stream. A "live" software limiter would costs a lot of performance and wouldn't makes sense. There exists a lot of hardware limiter for the client's end.

The transcoder is not more supported and if i'm right then had this function with the timeoffset never worked correctly. Don't forget that the transcoder was everytime a BETA version. The playlists are running until the last file is ended. So i would create simply a playlist with exactly this playtime and then you don't need the timeoffset.

#1 it isnt the dj its the quality of different mp3/wav/whatever music.. and ive a lot of ressources on my server (8 cores & 32gb ram so nvm..) we just have great exp. djs who are playing every week live on different locations so pls stop with something like this if you dont know anything of it.... i know too that the djs could do it with a limiter on their devices but i wanna control it over the server (if its possible.. my linux skills arent the best) and ye things that i have already known.. but thanks for the answer

if the stream is "over cooked" at the source, there's feck all you can do on the receiving end of the stream ... the damage has been done, it's called clipping, "information" has been lost and there's no recovering from it, you could have 100 cores and terabytes of RAM, and it'll still sound like a wogs car stereo

p.s. "great exp djs" aren't that "great" or "exp" if they play music that "clips" - that's my 2 shekels worth

why is it so difficult to get just an answer of my question.. i dont need explanations!
the guy who played the first time over our radio (with the scratches) is a well known local dj in bratislava/sk.. dunno maybe it was his mistake but idc.. so your whole answer means "no i dont know about a limiter between audio input from an external source to audio output to the listeners"

"sound limiter" question is done here.. BACK TO TOPIC --> calender events

what makes you think you don't need explanations? you clearly misunderstood the answer given

actually, no. My whole answer is "a limiter would not fix the problem at the point you want to put the limiter" - have you heard the phrase "shutting the gate after the horse has bolted"

your first question was about limiting, I apologise for giving an answer that was more than "no" - given that even with the explanation you misunderstood the answer, I can imagine a simple "no" (which would be an answer only) would elicit even more derisive responses from you

Do you have misunderstood the timeoffset?

Btw:
transcoder != Shoutcast
transcoder = not more supported

I know exactly from what i speak if a DJ can't hold his volume level. If a DJ has a difference from track to track inside a dj-set from more than 1,5 db and he can't see it when his volume is over the top, then this DJ is far away from a PRO. A good DJ would see the difference on the levelmeter on his djmixer and can adjust it while the prelistening. If not, then the DJ should do his homework.
