Start Recording Audio: Option to to ignore silence

[dah]

Hi Martin,

It would be great if you could add an option for the action Start Recording Audio to ignore silence (or even better, noise below a certain volume).

For example, I'd like to create a voice note taking flow that I can use while reading a book.

This would also be useful to create a Automagic version of the app Alibi (https://play.google.com/store/apps/deta ... libi.alibi).

This feature would probably useful most of the time the action Start Recording Audio is used.

What do you think?

Best regards,
Daniel

Hi Daniel,

I have the feeling that this could get quite complex, especially since audio processing is not really my field of experience.
I'll take it to the list of features under consideration but I will not be able to start in the short term since the list is already quite long...

You could try to use trigger Sound Level to start recording when the sound level is above a certain level but this will most likely miss the first spoken word and you would have to disable the flow containing the trigger so that the microphone is released and action Start Recording Audio can start to record the audio.

Regards,
Martin

Thanks, Martin.

I'll try your workaround.

Best regards,
Daniel

I just stumbled upon the following StackOverflow question which may be useful when you try to implement this feature:

The first answer seems to have a working code example.
