title: Javascript alternative to JavaSonics ListenUp
body: <p>I'm working on a server that has been using <a href="http://www.javasonics.com/" rel="nofollow noreferrer">JavaSonics ListenUp</a> (written in Java) to record audio via browser at clients and upload it to the server.</p>
  
  <p>The problem is: the software was discontinued, no longer updated or supported, and, because it's Java, it doesn't run on every web browser, as Google Chrome/Chromium and Microsoft Edge, for example, don't support NPAPI plugins (like Java) anymore.</p>
  
  <p>I wanted to know what can I use for the same job (record audio, upload audio files, play audio) to put it on the website I'm working on. Alternatives on Javascript would be awesome!</p>
  
  <p>PS. There's a <a href="https://stackoverflow.com/questions/1261743/record-audio-and-upload-as-wav-or-mp3-to-server/">topic here</a> where people talk about flash tools, but I'd rather not use them. Plus, I guess people who used that JavaSonics software might want an alternative also.</p>
