Is there a program for Ubuntu that can record sounds of only the output of the speaker and not any voices from outside the PC?

So you just want to record the output sound of a website? I think almost everyone here thought you were talking about sounds of your computer components :D

If I'm not wrong, then I guess you are talking about recording "Stereo Mix" or loopback Output.

In layman's terms, Recording Stereo Mix means recording sound from speaker output.

Here's how to do it:

Install pavucontrol from Ubuntu Software Center.

Install audacity from Ubuntu Software Center.

Select pulse* as recording device in Audacity.

Click Record Button.

Open PulseAudio Volume Control (Search For PulseAudio Volume Control in Dash).

Select Recording Tab.

Now You Should see ALSA plug-in [audacity]. If you do not see ALSA plug-in [audacity], make sure you have clicked Record Button in audacity. You should be running recording in audacity while performing next step.

Select "Monitor from *". See screen shot.

Now you should be able to record the sound you hear from speaker or headphones.

Note: Tested in Ubuntu 12.10

A very small, bare-bones software that does exactly what you need, is called (rather obviously) "Audio Recorder", installed like this:

sudo add-apt-repository ppa:audio-recorder/ppa

sudo apt-get update && sudo apt-get install audio-recorder

Command Line

Install sudo apt-get install pulseaudio-utils lame mpg123

Search for your speakers and tap into your speaker's monitor stream pacmd list-sinks | grep -e 'name:' -e 'index' -e 'Speakers'

Play anything you want to record and type in parec -d alsa_output.pci-0000_00_1f.3.analog-stereo.monitor | lame -r -V0 - out.mp3

Hit ctrl+c to stop recording and play the recorded file mpg123 out.mp3

Minimalistic GUI

I fixed up a very simple GUI to do this. Pull all the files from here and run install.sh
Goto Dash and search for Record Speakers

Of course it's for playback. It's also useful for testing loopback recording software that the software can intercept what is played back. And parec wasn't able to intercept aplay's playback in my test on Ubuntu 14.04.

Consider removing the | lame [...] pipe and use --file-format=wav output.wav (for example). You can list the supported formats with parec --list-file-formats. Also, consider making a bit more clear the fact that you need to specify the device with the .monitor at the end. ^^

Nice, as this can do stereo playback recording. Looks like audacity can't do that.

you don't need necessarily the name of the source... you can also choose the index of the source : parec -d 0 | lame -r -V0 - out.mp3

I just made a small alias to record the PC audio output with one single command and stored in opus format instead of mp3.

Install the required packages:

sudo apt-get install pulseaudio-utils opus-tools

Edit your .bashrc file:

nano ~/.bashrc

Copy the line below and append it to the end of your ~.bashrc:

alias recaudio="parec --monitor-stream="$(pacmd list-sink-inputs | awk '$1 == "index:" {print $2}')" | opusenc --raw - $(xdg-user-dir MUSIC)/recording-$(date +"%F_%H-%M-%S").opus"

Save the file by pressing Ctrl+X (to close nano), then Y (for "Yes") and Enter (to confirm the file name).

Now load the new ~/.bashrc (or simply open a new terminal):
```
source $HOME/.bashrc
```

Then try, just type

recaudio

It will create a file in your Music home folder called recording-[DATE].opus.

Enjoy.

What does the --monitor-stream=... part do/mean? My list-sink-inputs is zero unless something's actually playing sound, then it would return a number. So this would have to be started after the sound is already playing?

This is lovely, thank you! Very neat, and though Audacity setup works, if you just need to record audio (to ogg, wav, mp3, etc), this is the solution.

Why would you go thru all the "hustle" with Audacity when this one does the job you need with a single click ... beats me.

A very small, bare-bones software that does exactly what you need, is called (rather obviously) "Audio Recorder", installed like this:

sudo add-apt-repository ppa:audio-recorder/ppa

sudo apt-get update && sudo apt-get install audio-recorder

Files are saved automatically to the ~/Audio directory.

Command Line

Install sudo apt-get install pulseaudio-utils lame mpg123

Search for your speakers and tap into your speaker's monitor stream pacmd list-sinks | grep -e 'name:' -e 'index' -e 'Speakers'

Play anything you want to record and type in parec -d alsa_output.pci-0000_00_1f.3.analog-stereo.monitor | lame -r -V0 - out.mp3

Hit ctrl+c to stop recording and play the recorded file mpg123 out.mp3

Minimalistic GUI

I fixed up a very simple GUI to do this. Pull all the files from here and run install.sh
Goto Dash and search for Record Speakers

Of course it's for playback. It's also useful for testing loopback recording software that the software can intercept what is played back. And parec wasn't able to intercept aplay's playback in my test on Ubuntu 14.04.

Consider removing the | lame [...] pipe and use --file-format=wav output.wav (for example). You can list the supported formats with parec --list-file-formats. Also, consider making a bit more clear the fact that you need to specify the device with the .monitor at the end. ^^

you don't need necessarily the name of the source... you can also choose the index of the source : parec -d 0 | lame -r -V0 - out.mp3

I just made a small alias to record the PC audio output with one single command and stored in opus format instead of mp3.

Install the required packages:

sudo apt-get install pulseaudio-utils opus-tools

Edit your .bashrc file:

nano ~/.bashrc

Copy the line below and append it to the end of your ~.bashrc:

alias recaudio="parec --monitor-stream="$(pacmd list-sink-inputs | awk '$1 == "index:" {print $2}')" | opusenc --raw - $(xdg-user-dir MUSIC)/recording-$(date +"%F_%H-%M-%S").opus"

Save the file by pressing Ctrl+X (to close nano), then Y (for "Yes") and Enter (to confirm the file name).

Now load the new ~/.bashrc (or simply open a new terminal):
```
source $HOME/.bashrc
```

Then try, just type

recaudio

It will create a file in your Music home folder called recording-[DATE].opus.

Enjoy.

What does the --monitor-stream=... part do/mean? My list-sink-inputs is zero unless something's actually playing sound, then it would return a number. So this would have to be started after the sound is already playing?
