javascript - Why would someone make an XHR to an URL generated by URL.createObjectURL? -

-

i trying understand example code libvorbis.js library. blob audio passed url.createobjecturl, url returned used in xmlhttprequest generates blob passed url.createobjecturl again, , last url used in download link. why xmlhttprequest necessary? can't use url first call url.createobjecturl in download link?

according author:

i did because encountered bug in chrome android wouldn't want play audio url generated encoded audio blob directly. xhr call workaround come @ moment.
