# Create the Alarm Database

For the `audiosec` module to identify a detected alarm, it must match the alarm against a template in its database. You must create a template for each alarm you want to identify.

Note: If an alarm template does not exist for a particular alarm, IDOL Speech Server still detects the alarm, but labels it as `<UNKNOWN-ALARM>`.

A template consists of a short audio recording of the alarm. HPE recommends that the recording covers one whole period of the alarm, and that the sampling rate matches the sampling rate of the audio to be processed.

Save the templates in a single directory, and then create a list that contains the file names (excluding file extensions and paths) of the templates. For example:

    alarm_2
    alarm_3
    alarm_4
    alarm_7
    alarm_9
    alarm_11
    alarm_12
