Tips
https://docs.audiorelay.net has easy to follow instructions for using your phone as a microphone. 

Instead of using a wireless connection, you can use USB tethering to completely remove the eventual lags and delays.

Your wireless speaker experience will vary depending on the Wi-Fi network and Android devices being used.
For example, some Android devices haven't been designed with low latency audio in mind.
If possible, connect your computer via an Ethernet cable.
Otherwise, try to use a 5GHz Wi-Fi network instead of 2.4GHz.
