Listening for subaudible tones

We have RTMP streams that we are transcoding in Wowza Streaming Engine that have local and legal ad breaks with 25 and 35 hertz tones embedded in the streams. Is there a way to set up a listener within Wowza to detect when one of these tones has been played?

Hi,

We don’t have anything that can detect frequencies in that way. I would think you would need to write a custom module to perform frequency analysis of the audio track. If you need assistance in that area you could ask at our Find a Consultant forum.
