Firstly I profess to know very little about the science of sound and I am struggling to find anyone who has done this with sox.
I am looking to build a VHF marine radio simulator on Windows and Linux using NodeJS and have identified sox as a possible way to both play and create the VHF radio or walkie-talkie effect. I am generating mp3 from a google speech recognition API and I can play that fine in the simulator with the app.
As an example this is what I would like to achieve.
Does anyone know the sox effects that could be used ? Or any other way ?
