1. Pick a quiet place with little background noise or echo. Bare, empty rooms with a lot of hard surfaces tend to have an echo. Also, try to be away from windows or places where outside noise may interfere.

2. Check your internet and make sure that you have a stable network connection. If you have access to various types of networks (data plan, hotspot, WiFi), try out each of these connections to discover which one works best for you.
 

3. Wear headphones while speaking. Wearing headphones during your livestream will significantly reduce background noise. This also ensures that audio emitted from your device(s) is drastically reduced (if not removed all together) .

4. Mute yourself when you’re not speaking. Also, remind your co-hosts to mute themselves when others are speaking.

5. Use a high-quality microphone or professional equipment (such as a recording interface) and set it up properly. Many modern high-quality microphones also have headphone outs.

6. Run a livestream in unlisted mode to test your audio before going live. 

7. Invite your friends to join your live show and ask for their feedback on the audio quality.
