# SampleFrequency

The `SampleFrequency` parameter specifies the sampling frequency of the audio (the frames produced by the module).

Note: If the FFmpeg library is enabled, the `wav` module can accept a variety of audio formats with different sampling frequencies. In such cases, the `wav` module converts the audio to the specified sampling frequency.

Note: To detect breaking glass using the `audiosec` module, HPE strongly recommends that the audio sampling rate is 16000 Hz.
