How to remove computer audio from voice audio recording


I am working with Audacity 2.0.4 on a Mac OS X. I am trying to record myself interpreting an English language video on Youtube into French (interpreting practice exercise). I’ve used Audacity to do this in the past but this time I am having trouble. When you listen to the Audacity recording after the fact, all you hear is the sound from the Youtube video, whereas usually you just hear me speaking.

Could this have something to do with the earphones I am using? They are not the ones I usually use and they do have a microphone but they aren’t anything fancy either. If not, is there a setting on Audacity I could change to fix the problem? Please help!


I would stop using Audacity 2.0.4 right away. The latest version is 2.0.6.

Which OS-X? If you have the option to upgrade to Yosemite (10.10) I would not. Audacity does not directly support Yosemite yet.

What kind of microphone do you have? How is your voice getting into the computer?

Do you have SoundFlower installed on your Mac? Recording internet shows on a Mac is normally hard work. There are no natural tools like there sometimes is in Windows.

Look at your Device Toolbar and see what the recording option is. Change it to show your microphone.


Thank you for the quick reply! I’m afraid I am really bad with technology and didn’t quite understand everything you mentioned…

To answer your questions, I did download Audacity 2.0.6 and I do not have Yosemite. I have a Mac OS X 10.9.5. I assume my computer microphone is what is picking up my voice. I looked into downloading SoundFlower but a) I’m not sure which installer link to click on and b) I don’t understand why using Audacity for this same exercise worked for me but before but not now… My Device Toolbar lists my “Built-in microphone” and I’ve tried switching between mono and stereo recording to no avail.

I just did a test and confirmed that the microphone picks up both my voice and the audio from the Youtube video. I just need it to stop recording the Youtube video so only my voice will be left.

Any ideas?

Thanks again!

I … didn’t quite understand everything you mentioned.

We can’t always tell when you’re following us. I can do this.

You told us the Mac was recording only YouTube sound and not you. It’s recording both now?

My Device Toolbar lists my “Built-in microphone” and I’ve tried switching between mono and stereo recording to no avail.

That should work either way. I’d probably stick with mono because the quality is the same and it takes up less room on the Mac.

Can you do a sample recording with your iPod earbuds or your original headphones?

I don’t think we covered this. What kind of Mac do you have? I’m typing on a Mac Mini. The short one without the CD drive. My field computer is a MacBook Pro 15".


I agree with Koz it would be easiest to use your usual headphones.

Do you normally record your voice without attaching an external microphone - is that what you are trying to do now?

Where exactly you are connecting that headset to the computer? If it connects to the USB port, you could try setting Audacity to record from that instead.

When you plug the headset in, does it connect properly and shut off the speakers on the Mac?
