This is a pre-processing (red) element. It is placed after a Source to enable Thimeo Stereo Tool audio processing and/or µMPX encoding and streaming.
| ! | Stereo Tool sink |
| Unusually for an audio processing element, you can create a valid PIPE ending in a Stereo Tool element (i. e. without a sink element). Because of the option to generate a µMPX output, this audio processing element can also be used as if it were a sink element. |
| ! | Configuring Stereo Tool |
|
The element configuration menu for the the Stereo Tool element only serves to manage the licensing and MPX modulation of Stereo Tool. The actual configuration of the Stereo Tool audio processing and µMPX encoding is done in its own browser tab in the regular Stereo Tool web UI. You can access this GUI by starting the configured PIPE and clicking on the Stereo Tool WebGUI icon in the toolbar to the right of the PIPE.  For help with configuration of Stereo Tool see the following links:
