If YOU made this project and WE can test it, then you can add "Show HN" to the title. It encourages the users to provide feedback. More info: https://news.ycombinator.com/showhn.html

Some feedback:

Perhaps you can add also a registration by email and facebbok.

I picked a random user, and the volume was too low, perhaps you can autoadjust the volume. (add a volume button?)

In that user, the initial part of the recording is a "click". Is it possible to cut the initial/final part? (Some minimal edition?)

Do you have a maximal recording time? A link to report abuse?
