# Audio Categorization

Audio categorization identifies and classifies audio segments, for example as "speech", "silence", "noise", or "music".

Configuration Parameter | Description
--- | ---
Input | The audio track to analyze.
SampleFrequency | The sample frequency of the audio to send to the audio service.
SegmentDuration | The maximum duration of a record in the `SegmentedResult` track.
Type | The analysis engine to use. Set this parameter to `AudioCategorize`.

## Output Tracks

Output track | Description
--- | ---
`Result` | Contains one record, describing the analysis results, for each identified audio segment.
`SegmentedResult` | Contains one or more records, describing the analysis results, for each identified audio segment. The maximum duration of records in this track is limited by the parameter SegmentDuration, so multiple records are created with the same ID when an audio segment continues for longer than this duration.
