QUESTION
I have been looking to cut a audio blob in Js, and return a cut blob.
The blob is registered using WebAudioRecorder.js and using the mic of your pc.
I already found this repo: mp3-cutter, but it is written in node.js, and require to have access to the filesystem.
I also found this one: audio-cutter, but it has a UI.

...ANSWER

To help, i wrote a little library called simple-mp3-cutter
