Ubuntu: How to hear my voice in speakers with a mic?



Question:

I have a USB microphone that I can chat on Skype, record sound etc. But how can I make it so that when my mic is on and I speak, Ι hear it in speakers live without having to record my voice first and then play it back? What apps do I need or where can I enable this option?

I'm running Ubuntu 10.10


Solution:1

Here is a solution that I've tested with Pulse Audio on Ubuntu 12.04.

  • Install PulseAudio Volume Control (pavucontrol)

  • Now we will route your microphone to your speakers. Do this by running the following command:

    pactl load-module module-loopback latency_msec=1  
  • On the Recording tab of pavucontrol, you can show all streams (combobox at the bottom) and then configure which microphone (if you have more than one) should loopback into the built-in analog stereo

To stop it running, run:

pactl unload-module module-loopback  


Solution:2

  1. First install PulseAudio Volume Control/pavucontrol.

    Either install via Software Manager.

    Or run this below command in terminal:

    sudo apt-get install pavucontrol  
  2. To start Mic to Speaker working, run below command in terminal.

    pactl load-module module-loopback latency_msec=1  
  3. To stop the same, run below command in terminal.

    pactl unload-module $(pactl list short modules | awk '$2 =="module-loopback" { print $1 }' - )  


Solution:3

You can do it with jackd and qjackctl.

The program jackd is an audio sound server daemon for Linux, and its counterpart qjackctl is a simple user interface that let you handle JACK audio server. From this you can virtually connect the output of your mic to your speakers.

You can install them from you terminal with:

sudo apt-get install jackd qjackctl  

After installing it, and running qjackctl the connections mentioned will looks like the following screenshot.

Note, I am a professional audio editor, I and use it each week recordings sesions.

HTH.


Solution:4

I've packaged up other people's answers into 'listen', a Bash script. Run this to listen to your mic input. It sleeps forever. Kill it (e.g. Ctrl-C) to stop listening.

#!/usr/bin/env bash    # Directs audio input (e.g. mic) to audio output (e.g. speakers),  # then sleeps forever. Stops audio redirection when it is killed.  # So, for example, plug your phone into the PC's mic, run 'listen',  # and listen to phone audio through your computer's speakers.  #  # Requires:  # sudo apt-get install pactl    set -e    module=$(pactl load-module module-loopback latency_msec=10)    function cleanup {      pactl unload-module $module  }    trap cleanup EXIT    sleep infinity  


Solution:5

Just use:

arecord -f cd - | aplay -  

If you wanna play while saving:

arecord -f cd - | tee output.wav | aplay -  


Solution:6

You can use audacity to amplify your voice by "playback while recording" feature. go to edit>preferences>recording> check software playthrough.
