# 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 `[Analysis]` section, add a new analysis task by setting the `AnalysisEngineN` parameter. You can give the task any name, for example:

       [Analysis]
       AnalysisEngine0=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.
   `AudioCategorizeServers` | The host name and ACI port of the Speech Server(s) to use for audio categorization. Separate the host name and port with a colon (for example, `speech:15000`). You can specify multiple Speech Servers by using a comma-separated list. Media Server can connect to only one Speech Server at a time, but you can provide multiple servers for failover. TIP: You can specify a default IDOL Speech Server to use for all audio categorization tasks by setting the `AudioCategorizeServers` parameter in the `[Resources]` section of the Media Server configuration file.
   `SampleFrequency` | (Optional) The sample frequency of the audio to send to the IDOL Speech Server for analysis, in samples per second (Hz).

   For example:

       [AudioCategorize]
       Type=AudioCategorize
       AudioCategorizeServers=speech:15000
       SampleFrequency=16000

   For more information about the parameters that you can use to configure audio categorization, refer to the Media Server Reference.

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