# Categorize Audio

To run audio categorization

1. Create a new configuration to send to Media Server with the `process` action, or open an existing configuration that you want to modify.

2. In the `[Session]` section, add a new analysis task by setting the `EngineN` parameter. You can give the task any name, for example:

       [Session]
       Engine0=Ingest
       Engine1=AudioCategorize

3. Create a new section to contain the settings for the task and set the following parameters:

   `Type` | The analysis engine to use. Set this parameter to `AudioCategorize`.
   Input | (Optional) The audio track to analyze. If you do not specify an input track, Media Server processes the first track of the correct type produced by the ingest engine.
   SampleFrequency | (Optional) The sample frequency of the audio to send to the audio service for analysis, in samples per second (Hz).

   For example:

       [AudioCategorize]
       Type=AudioCategorize
       SampleFrequency=16000

4. Save and close the configuration file. OpenText recommends that you save your configuration files in the location specified by the `ConfigDirectory` parameter.
