# NullAudioMatchAudioData

Removes (deletes) the audio from an audio match clip, but does not remove the training generated from the audio data.

After running this action an audio clip can still be recognized but the audio cannot be retrieved from the database and cannot be used to retrain Media Server. If future versions of Media Server feature enhancements to audio matching that require retraining, you will need to supply the audio again.

Type: synchronous

Parameter | Description | Required
--- | --- | ---
`database` | The name of the database that contains the audio clip. | Yes
`identifier` | The identifier of the audio clip to remove. | Yes

## Example

    /action=NullAudioMatchAudioData&database=music&identifier=clip7

    <autnresponse>
        <action>NULLAUDIOMATCHAUDIODATA</action>
