Listen to one track, while recording a second just by itself?

Post by LivingInternet » Mon Jul 08, 2019 5:58 pm

Hi, my searches on this led to over-dubbing, which I don't think is what I want.

I have an narration track in Audacity. It was done when I was much less good. I want to redo it, but with the same timing, because it needs to sync to an existing video.

So I want to listen to the old track in my headphones, while recording (roughly) the same thing from my mic in a new track.

I am fine with moving and editing that second track around later to sync up with the existing first track if there are minor sync issues. The sync between the two tracks does not have to be to the millisecond, anywhere close will work for this purpose. I will then save just the new track to WAV, and replace the old audio track in the video production.

So (a) I only want to hear the old existing track in my headphones, and (b) I only want the new mic input to be recorded in the new track.

I could open two audacity projects I suppose, and start recording from my mic in one project, and then start the play back of the old narration from the other project. However, I'd like to do this in one Audacity project for other reasons.

Hope this makes sense. Possible?

What you've described is overdubbing : tick the overdub box in Audacity preferences.

The recording device to select is the microphone, not the computer speakers, (a/k/a stereo mix).

BTW it's difficult listening to an out-of-sync version of what you are saying without stuttering

Thanks. That works. In Edit / Preferences / Recording / Playthrough, check the box "Other tracks while recording (overdub)".

Then:

Set headphones for output.

Set mic for input.

Track one is the old track I want to listen to.

Create a new second empty mono track, and position the cursor at the beginning.

Press record. I can hear the first track in my headphones playing back. I say the same thing into the mic, with of course a very slight delay which is fine, since I will advance this track in the video software (Camtasia) to line up with the old one later.

The new track only records my voice from the mic. I export just that new second track as wav, and import into the video software. I make sure the wave form lines up, pretty close, with the old track. I delete the old track, and render the video. All good.

If you're able to hear the old track whilst recording the new version,
overdub must have been ticked in Audacity preferences.

Hi

I am not sure whether I am missing something here.

Here is what I thought this post was about and I was hoping to find the tip to what I was looking for.

I have a track already recorded in Audacity.
I want to play it while recording on another track. That track should be a track it by itself.
Not an overdubbed track.

I am just not able to get this done in Audacity.

On preferences I have checked

Record on a New Track.

I do not have an option for Play Other Tracks, but no Overdubbing.

Looks like Playback and Overdubbing are tied together - unfortunately!

Any workaround for this in Audacity. (I do not want to other solutions of saving and playing those tracks elsewhere.

I want to record separate tracks (like on a MIDI sequencer) so they can be adjusted independently for volume, effects, mute and other things. Finally, I can combine all the tracks and export into an MP3 or Wav.

Looking forward to your clarification or tips from any one else.

Thanks in advance

Sri.
P.S I have the latest version of Normal Audacity as well as the Dark Audacity

As Audacity is a multi-track audio editor, "overdub" just means to record another track into a project that already has one or more tracks.
"Overdub" does not affect other tracks in the project.
"Overdub" is what you want.

You can announce live with wild track in your headphones. It takes practice. Your live mouth is two or three words late compared to the headphone voice. The resulting new track is almost perfectly matched to overall time and only wanders in word matching by a bit. Shift offset in post production.

The wild track can be from anywhere like a music player or a sound file on your phone. This appears like it would drive you nuts, but it's surprisingly easy with a little practice.

Jay Foreman has a live theater show where he takes a request from the audience and then plays the song and sings the words—late. Don't listen if you're high or drunk. It's super disorienting, but he said in an interview he's playing back the real words in his head and singing them late, a cousin to this live reading technique.

So no, I didn't just pull that out of my.....ear.

Steve/Kozokowski

Can you please re-check and tell me if I am missing something.
May be I did not make things CLEAR.

Unfortunately, for me (I have tested this on both Normal and also Dark Audacity)
when you turn on Play Other Tracks - IT ALWAYS OVERDUBS.

The new recorded track has the audio of the other tracks plus what I am trying to record new.

I do not want the other tracks to be recorded into the new track. That is I do not want OVERDUBBING.
Just want to hear the other tracks and what I am recording.

Thanks Sri.
