I normally recommend to look into web audio API instead of trying different JS libraries because everything is basically a wrapper of the native API. I think this would help: [AudioBuffer - Web APIs | MDN](https://developer.mozilla.org/en-US/docs/Web/API/AudioBuffer)

for upload you can also use drag and drop: [dragOver and dragLeave do not work - #6 by micuat](https://discourse.processing.org/t/dragover-and-dragleave-do-not-work/4208/6)

and for saving a file: [wavefile - npm](https://www.npmjs.com/package/wavefile)

if it’s more like a batch operation (if you know start/end time to trim) you can also consider editing on the server - which may be easier but has less flexibility on the editing.
