How to stream audio from Android device to PC or web-server? Is there any ready-made application that allows one to stream audio, over WiFi to from phone's microphone to a configurable IP-address and port-number ?

Have come across several applications that do the reverse, and some that are very purpose specific, i.e. baby-monitor, which do not fit my purpose.
Yes there are. Some which I found are for gaming live streaming like YouTube Gaming, Mobcrush &amp; Twitch. Some for screen mirroring and streaming like Screen Stream Mirroring Free. Some streaming videos and audios like AllConnect - Play &amp; Stream which supports DLNA/UPnP. Some also make your android a UPnP/DLNA streaming server like BubbleUPnP UPnP/DLNA, MediaHouse UPnP / DLNA Browser, Plex &amp; BubbleUPnP for DLNA/Chromecast.

Update: Also there Voip over lan apps like Wi-Fi Talkie FREE, WiCall : VoIP call, Wifi call &amp; Intercom for Android,. There is app for streaming android mic to Icecast servers called Cool Mic. Another streaming via HTTP/RTSP called LANmic and another called RtpMic.

Sorry I can't post more than 2 links with my new account. I posted the exact names of some examples though. I'm sure there are more but these were on the top of the lists and with massive number of users.
