Streaming to external hardware from a virtual environment can be a challenge. Nobody wants to connect physical audioboards to a host. Playout, processing and streaming should all be on the same, virtual, machine. Audio should be kept digital for as long as possible, without AD/DA-conversion as they only lead to lower quality audio. But even if a virtual environment isn’t used, it can be convenient to stream directly from your processing (i.e. BreakAway or StereoTool) to the transmitter site.

In both cases, Screamer is the solution! With Screamer, you can stream directly from the source to a transmitter, whether the source is Dalet, GML, Caliope, BreakAway, StereoTool or even Winamp! Screamer works with both physical and virtual audio boards (ie. Virtual Audio Cable or FlexConnect).


By using SDP (Session Description Protocol), Screamer is extremely flexible in its configuration. Mono PCM to an Exstreamer? No problem! 16-bit, 44,1khz stereo MP3 at 320bps? Still no problem. See SDP Samples for more information on SDP.

Screamer saves the configuration in plain text. This makes it easy to update with any text-editor. Need more than one configuration? Save your configuration to a different file and use it as an command line parameter when starting Screamer. This way, multiple instances of Screamer, each with their own configuration, can run simultaneously.

Screamer (Minimal Mode)

Screamer also has a minimal mode. This mode is only available when the application is streaming and it cuts the needed screen real estate into half. Multiple instances of Screamer can then be neatly stacked upon one another.

Screamer is not only suited for point-to-point-connections (i.e from the studio to the transmitter site), it also supports broadcasting/multicasting. That way, one single Screamer-instance can serve multiple receivers. This is specifically meant for use in schools or offices.

Screamer was designed to be used with Barix equipment, but it can be used with any reciever that supports the RTP-protocol. This also includes the populair mediaplayer VLC. The way Screamer was coded, it minimizes the load on the system and because of the use of RTP, the delay on the streams is close to nonexistent. This makes Screamer extremely suited for use in an situation with multiple editions.
