SAM Broadcaster Cloud Basics

Important things to know

This section contains some very important information on how SAM Broadcaster Cloud operates. To properly use SAM Broadcaster Cloud you will need to understand the concepts below.

This document refers specifically to SAM Broadcaster Cloud and not SAM Broadcaster Cloud Live Streaming which is provided by the integration of SAM Broadcaster Pro or the use of SAM Broadcaster Live-DJ.

Near real-time operation

SAM Broadcaster Cloud is not meant to be a real-time DJ solution where you pick the next track seconds before the current track is about to end. The concept for SAM Broadcaster Cloud is as an always-on, hosted broadcasting solution that you configure and then leave alone so all the hard work can happen in the cloud!

That being said it is indeed possible to operate SAM Broadcaster Cloud in a near real-time fashion where you manually build and organize the queue.

The problem is best explained with an example.
John is listening to his own station and receives a request from a listener that asks if John can play “James – Sit down” next. John hears that the current track “Dido – Thank you” is about to end and quickly searches for “James – Sit down” in SAM Broadcaster Cloud and drags it to the top of the Queue. But, a few seconds later “INXS – Need you tonight” starts playing and “James – Sit down” is still at the top of the queue. Why?

There are several reasons why John’s action was not in time.

  1. Firstly, the streaming introduces a delay. The streaming server keeps a minimum buffer of between 20 and 30 seconds. This not only allows the stream to start playing instantly when a listener first tunes in, but also protects the listener from internet problems and reduces the chance of buffering and audio anomalies, therefore, what you hear is several seconds behind what is happening in the cloud currently.
  2. Any change you make to SAM Broadcaster Cloud first needs to be synchronized with the cloud. This can take anything from 1 second to 20 seconds for a very big change.

A safe delay to work on is to assume that what you hear is 60 seconds behind real-time and schedule your content accordingly.
Don’t worry – after a while you will be quite used to this delay and learn how to manage your schedule accordingly.


TIP: If real-time is a MUST for you… then SAM Broadcaster is really the product for you. The right tool for the job as my dad used to say.


Tracks are stuck in the Queue and never seem to play?

Only tracks that uploaded and was processed by our cloud will play. If a track is not ready for playback then the rotation logic will simply skip the track until it becomes ready.

Turning your station on has a delay

Once you set the “on air status” to the “on” state and click on the player, you might notice a delay before the audio starts playing. This is mostly due to the fact that the streaming server first needs to fully buffer the stream.

The good news is that this buffer then allows new listeners to hear the audio much quicker as the streaming server can “burst” data to the listener filling the player buffer faster and allowing actual audio to start sooner.


Same track imported only once

SAM Broadcaster Cloud will only import a track with the same path once. If you drag an item at “c:\music\a.mp3” onto SAM Broadcaster Cloud it will be uploaded into the cloud. If you however drag the same file located at “c:\music\a.mp3” onto SAM Broadcaster Cloud  again, then the file will not be imported or uploaded again.

NOTE: If the item is dragged onto a Playlist then a new entry will be created in the Playlist, but the item will not be uploaded again.

This holds true even if you physically put a different file in the “c:\music\a.mp3” location. SAM Broadcaster Cloud will not detect a change because the file changed. If you need to upload a new version of the file currently the only option is to delete the item from the SAM Broadcaster Cloud library and then re-import the file again.

FUTURE: In the future there will be an Upload library filter where you can force a re-upload of an existing library item.

    Useful, but like some of the docs - dated.

    Unfortunately, there are 5 developers but only me writing documentation which is an additional task and not my primary role so unfortunately, the documentation will always be a little behind but we like to think the documentation is better than it used to be.

    Fully understand. Also, Now that the Mac is becoming more important in the life of SAM/Vibe, this page needs some serious updating for Macs. Currently it's Linux and Windows centric, but although it mentions Mac, the commands are quite different. Easy enough to figure out, but quite different.

    Problem. This does not explain why there is a delay between "music playing and going live DJ" ... there is more than a 15 second delay.
    Then, there is a long delay between going "off air" .. and the music resuming.
    In addition to THAT, its also "delaying" showing me ON AIR ..
    When "switched" to go ON AIR .. its still showing me "streaming" instead of ON AIR .. but I AM ACTUALLY ON AIR. So this causes a huge problem because I don't even know when to begin to TALK.
    Then it ends up kicking me off the streaming.. because there's too long of a "silence" between the music and my talking. That's only because it is NOT showing me ON AIR.
    Finally,. I realize I'm ON AIR .. because I don't hear any music playing at all.
    This is crazy. There should be SOME kind of way... that there is NO DELAY when you switch ...
    If you switch from SAMVIBE playing / on air ... to LIVE DJ being ON AIR ... there shouldn't be this long of a delay. Naturally, we would expect SOME delay .. but not as long as we are having. Its like 15 seconds or more.
    And that's the same thing that happens when we switch from live DJ to go back to SAMVIBE to play the music.
    PLEASE HELP. We have a live show coming up on Monday night ... JUNE 15TH .... and we are having this problem.
    The mic is working just fine ... but is this LONG delay ...
    Thanks Matthew ..

    Hi James, you are correct but the documentation is being updated and will be released as it becomes available.  The majority of the principles remain valid but some parts have moved.  If you have any specific questions or issues, please raise a ticket at and we will assist you.
