generate wav file from sprite

[JJMeric]

Hello all,

My field is audio for the study of languages.

Not sure I use the right words. Here is what I am trying to do:
Extract a part of a wav file on the server (a sentence in a recorded dialogue) : this looks like a "sprite" in Howler.
Then, generate a smaller wav file with just that extract, and provide this as a link for download.

So far I have provided play start and end times for the tag like this : my_dialogue_file.wav&t=49.306,51.491
This works fine, but now I would like to pass that extract to specialized program, Praat. And Praat does not handle my_dialogue_file.wav&t=49.306,51.491

Thanks for help, tips, other approaches/tools
