Use your android phone as a karaoke microphone in Linux.md

micclient+WoMic is close source, while Mumble is open source, so on armbian tv, I can only use Mumble+Murmurd+Plumble.

===================="mumble+murmurd"(on arm64 armbian linux tv)+plumble(on android/ios)==================== refer: https://github.com/diyism/mic_over_mumble

sudo apt install mumble mumble-server

sudo systemctl stop mumble-server.service

sudo /lib/systemd/systemd-sysv-install disable mumble-server

wget https://github.com/pzmarzly/mic_over_mumble/raw/master/mic_over_mumble

chmod 744 mic_over_mumble

./mic_over_mumble

#config echo cancellation

#config minimal delay 20ms

#next next and exit and murmurd server started

#muble client started, input a random user name

#install plumble free version on your phone

#start plumble and cancel certification generation

#input a random user name that is different to the mumble client user name on armbian tv

#now you can sing to your phone, and your voice will be played on the armbian tv immediately

===================="micclient-x86_64.AppImage"(on amd64 linux pc)+Wo Mic(on android)====================

If your linux release is using pavucontrol(pulseaudio), you should do:

$ pulseaudio -k
$ killall micclient-x86_64.AppImage
$ sudo modprobe -r snd-aloop
$ sudo vi /etc/pulse/default.pa

add into default.pa:

load-module module-alsa-source device=hw:CARD=Loopback,DEV=1,SUBDEV=0

$ sudo modprobe snd-aloop
$ pulseaudio --start
$ wget https://wolicheng.com/womic/softwares/micclient-x86_64.AppImage
$ sudo chmod 777 /usr/bin/MicClient
$ sudo mv micclient-x86_64.AppImage /usr/bin/MicClient
$ while true; do nohup MicClient -t Wifi 192.168.1.100 > /dev/null 2>&1; sleep 1; done &

192.168.1.100 is my phone IP in local network, you should change it to your phone's LAN ip.

In pavucontrol(Volume Control), in "Input Devices" tab, enable "Built-in Audio"(not "Built-in Audio Analog Stereo") as input device.

And redirect MicClient audio to virtual output device, first in "pavucontrol/Input Devices" to tick "Built-in Audio" to "Set as fallback" and then:

$ pactl load-module module-loopback latency_msec=1

Now with WoMic in android and micclient-x86_64.AppImage in x64 linux, you have a set of home karaoke equipment with near 0 latency.

If you hear many noises, you could try to switch the "WO Mic Settings/Audio source" in your android phone, for example: nexus 6p should choose "Mic(mode 2)".

To disable redirecting MicCleint audio to Output Device:

$ pactl unload-module module-loopback

(I know I'm replying to edits that are now gone)

It's been extremely stable for me. It was also super easy to set up since the script does most of the work. I basically just set mumble up (basically changing quality/latency to be max/min) like it tells me to (It even automatically opens it), then every time after that I just need to run the script and connect from my phone using plumble.

Do not need any software (unsafe blobs in you linux! :))
If you have jack3.5-jack3.5 cable. You can just setup application from google market as

https://play.google.com/store/apps/details?id=com.ozan.netbooster&hl=en_ZA&gl=US

This app can route mic input to audio output of your phone, so, you can connect phone output by jack3.5-jack3.5 cable to PC mic input. It is all :)

After trying the micclient-x86_64.AppImage"(on amd64 linux pc)+Wo Mic(on android), nothing worked, apart from arecord. However, I was still playing around with the fix, until I did killed pulseaudio and started it again, then the Buitl-in Audio appeared in the pavucontrol settings (which does not usually appear, usually Built-in Audio Analog Stereo and Loopback). And then it works. I played with the success for sometime using cheese, and then decided to give it a try on Whatsapp, then I noticed some obnoxious sound result, until it no longer works. Worst part was that even my built-in audio output no longer works. I made a reboot, and all the settings were gone. I don't know how I came about the Built-in Audio, as it's the obvious solution. So please if there's a definite way of activating the Builtin-Audio instead of Builtin-Audio Analog stereo, I'll be glad to know.

Plus after rebooting, even arecord no long records any sound using the micclient loopback device, which initially does. Please I really need this to work, or if there's another best option for me, since my laptop's mic is malfunctioning. Thanks

EDIT:
arecord now works with the micclient loopback device
Would have tried out mumble but the plumble is not available for my andriod device, it says it's meant for older devices
