It was closed for this reason:
Closed. This question needs details or clarity. It is not currently accepting answers.
After it was closed, I edited it to add paragraphs of clarity and details. However, it still remains closed. A moderator commented:
You might want to add the link to the "traditional" Help Center where this things belongs - support.google.com/pixelphone. The specfic help article (is the same from one of the screenshots): Record audio on your Pixel phone. Please remove the meta commentary.
This is confusing to me. What details or clarity does this question lack? The question is extremely clear and detailed, does it really need to be even more detailed? Why am I pointed to a help article that doesn't answer the question? The help article says how to upload audio using a Pixel phone. It doesn't say how to upload audio using a web browser. Maybe there is a way that isn't mentioned in the help documentation. Power users of web applications often find ways to do things that are undocumented. As a power user of recorder.google.com , I am interested in finding out if there is a way to upload audio using the web interface.
If the question should be closed for another reason, then why was it closed as lacking clarity or details?
Since apparently the meta commentary should be removed, I've asked the question here.
