The p5.sound library creates a Blob object before download it as .wav, you can see this on p5.prototype.writeFile.

The difference between a Blob and a file is just 2 extra properties: a date and a name, so, if you want to "convert" your blob to a file, just add this 2 properties:

function blobToFile(theBlob, fileName){
    //A Blob() is almost a File() - it's just missing the two properties below which we will add
    theBlob.lastModifiedDate = new Date();
    theBlob.name = fileName;
    return theBlob;

After that, you can manage the output as a javascript file
