Use new telemetry histogram ID 'AUDIO_TRACK_SILENCE_PROPORTION' to know the proportion of
silent part in the whole audio track.

Do you expect this measurement to be dominated by a value of 0? It might be worth either excluding 0s or making a separate measurement for them, depending on how you hope to analyse the data (which is one of the questions asked in Data Collection Review: https://wiki.mozilla.org/Firefox/Data_Collection).

We would want to know how many silent audio track in the web comparing with normal media content in the web, so we can not exclude the 0% silence.
