Wo mic arch linux

Use phone as microphone in Linux

I have dual boot Windows and Ubuntu. Since I don’t use any microphone on my desktop, I started using an app named «WO Mic» to connect my Android phone’s microphone to my desktop in Windows. A good alternative, right? Well, sadly, WO Mic is not supported on any Linux-based OS, so I would like to know if there are any alternatives or any app that could use my phone as microphone on Ubuntu over Wi-Fi or USB. (but preferably Wi-Fi).

I use Mumble (desktop client) + Murmur (as LAN server) + Plumble (Android/iOS client). This results in the lowest latency I’ve ever achieved (sounds almost like normal loopback, theoretically 7ms WiFi delay + 2x 10ms codec delay = 27 ms).

For the latest version, see github.com/pzmarzly/mic_over_mumble.

Fragments of README (rev 8c827fe)

1. Install Mumble (desktop client) + Murmur (server) + Plumble (Android/iOS client). Set all 3 programs to use best quality and minimal latency. Set mobile client to always streaming.
2. To install Mumble + Murmur on Ubuntu, you can use:

sudo apt install mumble mumble-server sudo systemctl stop mumble-server.service sudo systemctl disable mumble-server.service 

Copy mic_over_mumble anywhere — it will use ~/.mic_over_Mumble as configuration directory.

Run mic_over_mumble . It will start the server on LAN, then start Mumble (if asked for nickname, enter anything other than SuperUser). Then connect your mobile device to the LAN server manually. Please note that Mumble mobile app has some issues.

Then, set up your programs to use either «Monitor_of_Mumble» or «VirtualMic» as input device (they are linked). E.g. in OBS:

Copy of mic_over_mumble script (rev 8c827fe)

#!/bin/bash set -euo pipefail # PAID = PulseAudio ID # / process ID function main () < if [ ! -e ~/.mic_over_Mumble ]; then mkdir ~/.mic_over_Mumble fi cd ~/.mic_over_Mumble rm murmur.ini || true echo "bonjour=true" >> murmur.ini echo "bandwidth=130000" >> murmur.ini if [ ! -e ./initdone ]; then echo "You will need to configure Mumble client to use the lowest possible latency." echo "We will start Mumble now.

Arch Linux

my guesses resulted that it might be a delay in transfering data via old android phone’s hotspot and for that, i tried to create AP on my own Arch Linux (using Create_AP script) to reduce the delay as much as possible, but now again im getting the same result : noisy and unclear sound input

Im sure its not a hardware problem because im having a really clear voice on my iphone, but Womic just makes it noisy on my Arch Linux (works fine in windows, i have tested now)

1. I load the snd-aloop module (needed by womic) using the command below :

2. I run WoMic to connect to my iPhone :

sudo ./womic -t WIFI 192.168.12.19

3. I start recording sound using arecord from that sound input :

arecord -c 1 -r 48000 -f S16_LE -D "hw:CARD=Loopback,DEV=1,SUBDEV=0" Desktop.wav

this is my sound card info :

╭─erfan at erfan in /home/erfan ╰─λ lspci | grep -i audio 0 < 14:16:15 00:1b.0 Audio device: Intel Corporation 7 Series/C216 Chipset Family High Definition Audio Controller (rev 04)

edit : i also have tested sound in-action by using simplescreenrecorder and using ALSA input config on hw: 1,1 and getting the same sound on screen record

Re: WoMic noisy and unclear sound

Also i have to mention im getting the error below after it connects in terminal :

ALSA lib pcm_dmix.c:1108:(snd_pcm_dmix_open) unable to open slave

this is the complete output and the command :

╭─erfan at erfan in /home/erfan/Wo Mic ╰─λ sudo ./womic -t WIFI 172.20.10.12 0 < 13:28:37 Connecting. ALSA lib pcm_dmix.c:1108:(snd_pcm_dmix_open) unable to open slave Connected

Re: WoMic noisy and unclear sound

Guys I have tested this feature on a live ubuntu on my laptop (the same laptop that im using arch linux) and everything worked fine !

so whats wrong with arch linux ? can u guys test wo mic on your own arch and tell me the result ? what could be possibly causing this issue ?

Re: WoMic noisy and unclear sound

dmix failed to open slave means it couldn't open up your default ALSA device. As you are using pulseaudio, you will want to install pulseaudio-alsa if you haven't yet.

I already have pulseaudio-alsa installed

Re: WoMic noisy and unclear sound

Hi, I hope this is not a necrobump, but as the question is still there and not fixed and all the paramaters still remain the same, so I continue this thread.

I'm getting the Unclear and Noisy (a robot like sound which has scratches in it) when i use Womic, I can assure you my iPhone's soundcard is fine cause I tested it and is ok, I also can assure you I have tested it on Windows and Ubuntu and they both work fine !

Here are my commands and their output :

Как использовать Wo Mic в дискорде на Manjaro?

Установил на Manjaro программу WoMic, юзал на Win10, очень удобно было. Перешёл на Manjaro. Тут она тоже оказалась. Подключился через Bluetooth. Написало Connecting. Connected. В интернете есть способ как записать голос в аудио, но как в live-режиме использовать нет. Помогите как это сделать!

Простой 1 комментарий

fuse2 should be added as a dependency (needed to open the .AppImage file)

Also, I wasn't ever to get this to work correctly. The Windows version worked fine for me but this Linux version is lacking. It has no PulseAudio support, very limited configurability and documentation, and is just a binary blob in an AppImage. I was trying to use this for Discord (which requires PulseAudio) but I couldn't get any PulseAudio applications to record sound off this thing no matter how much I fiddled with settings. The only thing I was able to do was record a .wav file using arecord but even that sounded extremely choppy.

I settled on using Mumble instead with this small bash script I found to set up a virtual mic in PulseAudio. GitHub link with instructions here: https://github.com/pzmarzly/mic_over_mumble

All the mumble software is open source and in the main Arch repositories and I have no problems with sound quality or getting it to work in Discord (or any other PulseAudio application since the implementation is done entirely in PulseAudio itself.)
