[PD-dev] Detecting the index of the first non silent sample in an audio file

[Pascal]

Hi,

I have an audio file that I read with [tabread~]). The audio starts with some silence and I am trying to find the first non silent sample index.

I have tried to use [bonk~], [fiddle~] or [sigmund~] but the results were approximate and not constants.

Does anyone have a solution for this? Thanks.
