looks like you ask for some help for p5 sound lib?  
but if you have the file already  
( downloaded to your browser download folder )  
can use a good external audio tool:

hi @ahmedali I might be wrong but I don’t think there is a single function for trimming audio yet.

Have you watched this tutorial on sound? - [https://www.youtube.com/playlist?list=PLRqwX-V7Uu6aFcVjlDAkkGIixw70s7jpW](https://www.youtube.com/playlist?list=PLRqwX-V7Uu6aFcVjlDAkkGIixw70s7jpW) . 17.3 of the tutorial talks about going from one point of a song to another and setting up cues at a certain point in a song and other topics that deal with sound.

Other than that as of right now, i 2nd what @kll suggests. But, feel free to give us more detail of your project if you wish. Maybe there is another solution.
