Tutorial - Recording Computer Playback on Windows
Choosing the recording device in Audacity
Choose "MME" or "Windows DirectSound" in the Audio Host box of Device Toolbar and the sound device's input for recording computer playback in the third (Recording Device) box of Device Toolbar. You can also choose this recording device at Recording Device in Devices Preferences.
You must play the audio you want to record using the same sound device that has the "Stereo Mix" or similar input.
You cannot play audio through an HDMI output or through a headset,
headphones or speakers that connect via USB or wirelessly then record
that playback using the stereo mix input of the built-in sound device. Choose the Windows WASAPI host (next section) if you want to record playback of a USB, wireless or external sound device.

should be off when recording computer playback, so if Software Playthrough has a check mark, click that item to turn it off. Otherwise you will hear and record echoes or distorted sound. |
Windows WASAPI loopback recording
On Windows Vista, Windows 7 or Windows 8 only you can choose the Windows WASAPI Audio Host and then the (loopback) input in the Recording Device box. Choose the loopback input for the computer playback device you will be listening to (for example, "Speakers (loopback)" ). The loopback input records computer playback even if your sound device lacks its own stereo mix or similar input:

Tutorial - Recording Computer Playback on Mac
Use Soundflower
Soundflower is a free open source system add-on for Mac computers that allows you to route what is playing on the computer digitally back to the input without using a cable. Set Soundflower as your system output device, then in Audacity, set Soundflower as your recording device.- Download the latest version of Soundflower. It is possible that older versions of Soundflower may work better on older versions of OS X. Older versions of Soundflower may be obtained if necessary at https://code.google.com/p/soundflower/downloads/list.
- If the downloaded zip file does not extract automatically,
double-click it to extract the DMG file it contains, or use your
favorite extraction utility. To install the extracted DMG file,
double-click it to mount it. In the DMG itself, double-click the PKG
file.
If you see a warning on OS X 10.7.5 or later that Soundflower cannot be opened due to your Security Preferences, right-click or control-click over the PKG file and choose "Open", then choose "Open" again. - After opening the PKG file, you may see a warning that the certificate for the installer has expired. Press "Show Certificate" to review the certificate then choose "Continue".
- Then run through the standard installer steps. Save your work in other applications, then press the button in the installer to restart your Mac.
- Choose and select the Sound preferences panel.
- In the Sound preferences panel, choose the Output tab, then
select "Soundflower (2ch)" from the "Select a device for sound output:"
list and turn the Output volume up.
- In the same panel, choose the Input tab, select "Soundflower (2ch)" and and turn the Input volume up.
- At this point you will no longer be able to hear what is playing on the computer. The sound output of the computer is being sent to Soundflower.
- Click on the "Sound Effects" tab, and from the "Play sound
effects through" dropdown menu choose "Line Out", "Headphones" or
"Internal Speakers" (whichever is appropriate for your system).
- This will route some system alert sounds (such as Mail
alert sounds) to the Line Out or Internal Speakers and not to
Soundflower. Thus these sounds will not be recorded by Audacity.Some
Macintosh applications are better behaved than others when it comes to
alert sounds. Tests on a recent iMac running 10.7.2 show that Mail and
TextEdit alert sounds will not be recorded with the above setup, but
iCal and Yahoo Messenger alert sounds will be recorded. To be
safe you should disable the sound on any iCal alerts that may occur
while you are recording, and quit any other program that may make an
alert sound.

or similar as Playback Device and Soundflower (2ch)
- Click on the menu and make sure that "Software Playthrough" is checked.
- Go to the application that will be playing the sound you want to record. For example, start Safari and go to a website that plays sound clips. Start some audio playing.
- Click on the recording level meters (beside the microphone symbol) to begin monitoring:
- You should now be able to hear the sound playing on your computer.
- Now click Record to record anything playing on your computer.
To set things back to "normal" so you can hear audio playing on your computer without running Audacity
1) Click on then the Sound panel, and select the Output tab. Select "Line Out", "Internal Speakers" or "Headphones" in the output device list. See step 3 above for an illustration.2) In Audacity, if you want to record from a different source (such as the Line Input or an external USB device), click on then the Devices section and select the input you want to record from in the Recording section. See step 7 above for an illustration.
