# Audio Categorization Results

The following XML shows a single record produced by audio categorization.

    <record>
      <timestamp>
        <startTime iso8601="1970-01-01T00:00:01Z">1000000</startTime>
        <duration iso8601="PT00H00M00.500000S">500000</duration>
        <peakTime iso8601="1970-01-01T00:00:01Z">1000000</peakTime>
        <endTime iso8601="1970-01-01T00:00:01.500000Z">1500000</endTime>
      </timestamp>
      <trackname>AudioCategorize.Result</trackname>
      <AudioCategorizeResult>
        <id>e8d84838-bdf2-4b9b-9a92-e7e42b249103</id>
        <category>Music</category>
        <confidence>80</confidence>
      </AudioCategorizeResult>
    </record>

The record contains the following information:

- The `id` element contains the identifier for the audio segment.

- The `category` element shows how the audio segment was classified. The categories are pre-defined and this value can be:

  - `DialTone`
  - `DTMF-*`, `DTMF-0`, `DTMF-1`, `DTMF-2`, and so on. These values indicate that the audio contains a DTMF tone. For example, `DTMF-2` indicates the tone for the "2" button.
  - `Music`
  - `Noise`
  - `Silence`
  - `Speech`

  NOTE: Dial tone and DTMF tone detection are enabled only when you process audio with a sample rate of 8KHz.

- The `confidence` element provides the confidence score for the classification, from 0 to 100, where 100 indicates the greatest confidence.
