Thanks for acknowledging and working on it. As a unpaid customer I can surely wait :)

Can I sneak in a couple of questions while I have your attention?

1. The upload says it only accepts MP3 and WAV -- but it seems to accept AAC as well in the past when we force it to? Also, why not support all other commonly used audio formats as well - should be (relatively) simple to add a conversion step?

2. Can we get some controls on how aggressive the noise filtering applied is? The result in some cases sounds like abrupt cuts, flubbed words, speaker suppressing a hiccup or burp etc :))

Oh and a suggestion --

If the issue we saw yesterday was due to a service being down or broken, ideally the error message displayed should say so -- so users don't assume the issue is on their side with their input file and try repeatedly and waste their own time.
