# 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 to use when analyzing the audio.
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.
`ResultWithAudio` | Contains the same information as the result track, but also contains the audio. You can use this track as input for a Speech-To-Text analysis task. Speech-to-text ignores any segments that are not labeled as "speech".
`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.

For more information see Audio Categorization Results or use the action GetExampleRecord.
