Bot to test audio

Discord's mic test in its settings is pretty inconvenient for me since I'm hearing the audio at the same time as I'm testing it. It's like an echo and it's distracting to tell what's my actual voice versus what the audio actually sounds like.

Would be nice to have a bot, like on Skype or Microsoft Teams, where you make a test call and they play the audio back to you. Or some equivalent like that.
