Dear all
I want to apply a fade in to 100 sound files.
I’d like to apply a batch processing.
Many thanks for hints, tricks and support

You need to use a Macro.

See this page in the Audacity Manual:

And this Muse support site:

Hi Peter
Many thanks for your answer.
I’ve tried it.
I would like to apply the fad in only the the first 1-2 seconds of the sound file
With a macro I was not able to achieve that - the Fade in was applied to the whole file.
Many thanks for additional hints
Martin

Like in the screenshot? It’s a very strange task.

Catch macros:

SelectAll:
FadeIn:Use_Preset=“”
ExportWav:

P.S. Do not forget that the path for files output by macros must be specified in the settings.

Take a look at the included “Fade Ends” macro to see how to select the start of the track.
