Hello,

I am using Audacity 2.1.2 (from the exe installer), on Windows XP.
I have a project, where I start with one drum audio track.
Now, on a second track, I want to record some guitar. I hear the 1st track (the drums) over my headphones, while I record the guitar over a microphone with a jack which I plug into my PC. All of this works fine: I can hear the drums fine and the 2nd track is recording the sound of the guitar. However, the problem is that in the 2nd track, apart from the guitar I also hear the 1st track (the drums). First I thought somehow the sound of my headphones would reach the microphone, but even when during recording - for testing - I put the headphone faraway, under a pillow or something, the same happens: the sound of the 1st track is also recorded on the 2nd track together with the newly played guitar. How can I avoid this? Because the next step would be to add more guitar-tracks and - finally - vocals, and when on each new track all previously recorded tracks are heard too, it is impossible to mix. Of course, I could mute the 1st track while recording, but I need those drums to play the guitar on time.
What am I doing wrong here?

Best regards,

Machiel

I would have thought we'd had a pre-baked answer to this already.

You're on headphones, check.

Do you like recording on-line content like YouTube sound? The settings to do that, can do this.

Audacity > Edit > Preferences > Recording: [X] Overdub. That should be the only thing selected.

Audacity Device Toolbar > Microphone Symbol (recording). That should be your single recording device such as USB input, Line-In or Built-In Microphone. It should not be the setting you use for recording YouTube videos, such as Stereo Mix or What-U-Hear. Those aren't real devices. Those are "fake" false pathways inside the machine.

Some USB sound mixers can do this as a production feature.

Am I close?

Well, I actually tried to google for an answer, and found a few replies, but none of them worked for me.

Check.

No.
I have an audio track (recorded somewhere else) which is a drum track. "Track 1".
Now I open a new track "Track 2", where I record the guitar. I need to hear the drums, obviously, to play on time. I can hear the drums fine, and the microphone does record the guitar as played in front of the microphone. But somehow when, next, I listen to Track 2 (muting Track 1), I not only hear the guitar but also the drums.
This happens even when during recording I unplug the headphones and switch off the microphone (for testing): the sound of the drums still end up on "Track 2". So, somehow, somewhere track-1 "leaks" into track-2.

Audacity > Edit > Preferences > Recording: [X] Overdub. That should be the only thing selected.

Correct. Check.

Audacity Device Toolbar > Microphone Symbol (recording). That should be your single recording device such as USB input, Line-In or Built-In Microphone. It should not be the setting you use for recording YouTube videos, such as Stereo Mix or What-U-Hear. Those aren't real devices. Those are "fake" false pathways inside the machine.

I don't record YouTube videos. I found on the net some replies refering to "Stereo Mix" or "What-U-Hear", which - supposedly - are settings on Windows, right? The problem is, I cannot find in any settings (Sound, Microphone, etc...) on my Windows these settings at all. Which makes me think my PC (or soundcard) somewhere hidden has these options set without giving me the chance to switch them off.
This morning, I tried something else: I copied my entire ".au" project to a different computer (Windows Vista, laptop), and got the same Audacity version installed there. Here, it doesn't happen. As a matter of fact, here I cannot find this "Stereo Mix" or "What-U-Hear" option either, but in any case, it seems I don't need to, it works fine here.
So my conclusion is that somehow this "leaking" depends on either the OS (Windows XP) or on the soundcard (RealTek on XP, Microsoft High Def. Audio on Vista). For the moment I continue on Vista, although it would be easier for me to work on XP because it has more memory.

Am I close?

I think you are right about the "SoundMix" and "What You Hear" options, but unfortunately I cannot test this because I cannot find this on my computer. (Which by the way, is installed in the Spanish language, but anyway, I haven't seen anything that could be rougly translated to those words).

Anyway, thanks for your advice, I think you are right, even though it doesn't solve my problems your help is very much appreciated.

Cheers,

Machiel

In the Audacity Help menu, select "Audio device info". Wait for the info to appear, then copy the full contents of that window (Click at the start, then scroll down to the bottom, then shift+click at the end, then Ctrl+C), and past it into your reply. That will show us what devices Audacity can see on your computer and may allow us to advise more accurately.

Can you describe all the audio ports and their colours on this XP machine? I don't understand why "Realtek HD Front Green Jack" is described in the Audio Device Info as a recording device. Green audio ports should be for playback.

Are there any built-in speakers on this machine? There do not seem to be, according to the Audio Device Info?

Can you connect your mic to the "Back Line in/Mic, Front Line in" port and choose that as recording device in Audacity? Does that have the same problem?

Did you build this computer yourself or is it a branded model? Bad audio drivers could be something to do with it.

There have been posts where we just couldn't figure out where the bad sound pathway was coming from. But yes. You have the idea. Close all the known sound pathways and keep trying.

Now I open a new track "Track 2", where I record the guitar.

I'm running that through my mind. That's not how I do it. That may cause conflicts because of the time-to-life nature of the tracks.

I set up for overdubbing with a simple microphone, but I don't create a fresh, new track to put the live performance in. I have the base or rhythm track and nothing else. I press Record, the rhythm track starts to play in my headphones and a new live track is laid down—usually by itself.

I need to drop out for a bit.

1) No, I disconnected all speakers
2) I have tried all possible in- and out- entrances of the PC, both for microphone as for headphone. The only ones that are working (unless I did something else wrong while changing) are the front inputs: Pink for microphone, Green for headphones.
3) It is a branded PC, but it's 15 years old, and still has XP. So I'm afraid that it will be very hard to fix if at all possible. Especially since it's all in Spanish. I'm pretty sure it has something to do with this "Get What You Hear" thing, but I have to figure out where that option can be unset (if at all).

Well, I tried both ways. Either just clicking "record" and then a new track is created automatically. (And track-1 will "leak" into "track-2"), or, making a track myself, selecting this track, and click "SHIFT -R" and recording then. In both cases, the same happens. I prefer creating the track myself, because then I can select "MONO" (but I've tried Stereo too, to see if that made a difference) (No, it didn't).

Cheers,

I'd like to add one more thing. I tried to do the same thing using CuBase instead of Audacity. The same thing happens (one track "leaking" into another). This - for me - definitely confirms that it's some setting on Windows or the soundcard which I have to change. The only problem left is to know whether that is possible and how.

In any case, many thanks for all the helpful advice.
