Merge two or more stereo or mono files on the timeline into one mono file

Something I never have understood is why it seems to be so complicated to merge two or more tracks together to one single mono file when exporting sound from Cubase.

Now I got the latest version of Cubase 15 PRO and thought that this issue with with far too many detours should have been solved once and for all.

But no way, its still the same advices that takes more time than necessary every time, at least when I try my best to do it in one go!

As it is now there are so many different suggestions of how doing this were all are time consuming for such an easy task.

I´ve been trying almost every method now, from “Render in place” to “Mix down to one Audio File” without a good solution.

What is the proper way to doing this, please?

Jack

Hi,

You can simply Export Audio Mixdown…

But, tell us more, please. What is your use case begging?

Mixing-down tracks isn’t complicated once you have everything set-up properly.

  • Make a Mono Group track (if you want a mono mixdown)
  • Set the Output of the tracks you want mixed to the Group Track
  • Set the locators on the timeline
  • Go to Export Audio Mixdown, use Single mode, and select the Group track
  • Export Audio

If that’s not working out for you, please post some screenshots.

Try Export As->Mono Downmix.
Never used this but it might work for you.
If it doesn’t, at least give us some of examples of what you have tried, so we don’t waste your time.

What you suggested was the first thing I tried a week ago. After that there been many different ways more or less complicated without the desirable result to merge down two or more files into one single mono file.

In my opinion this should not need to be so complex. Excuse me for sounding harsh but stuff like this gives me migraine and there seems to be no way out of this maze.

I´ll try to explain how things “not” work here with some text and images and sorry if it will be longer than a boring Sunday.

01-02. If I chose Export as Mono Downmix only one track at a time will be activated. See image 01 and 02.

03-04. I then chose multiple files. But what comes out of that is only two separate mono tracks with the same scenario as on the timeline and also a mono out file without any information or sound on. Please see image 03-04-05.

Thanks for the tip but may I ask you why this is not just as simple as it sounds like, to just mark the tracks you want to be included in the mono file.

I haven´t used group tracks in years since I couldn´t find a way to remove group tracks without that all the files included also were deleted. I don´t know if I even remember how to fix group tracks any longer, of course I can study tutorials and read your wise
information.

But somewhere it sounds to complicated for such an easy thing to do that even cheap sound programs or Audition fix in a blink. Here are some images that explains the way I tried to solve this, and then I am not adding what happened when I used Render in Place. That was even more strange.

Hi,

On your screenshots, I don’t see the Mono Group Channel, as advised here:

Here´s a memory of what I didn´t know when I removed the Group Tracks and lost all sound and instruments inside the Group Tracks. This is a kind
of complexity I believe Steinberg could have stopped by a simple question box before removing a Group Track.

”Do you want to keep or delete the sound or instrument tracks inside the Group Track”

”To remove Group Tracks in Cubase without losing audio or instruments, change the routing of all grouped audio/MIDI/instrument tracks back to “Stereo Out” (or your main output) in the MixConsole, then delete the group track. This ensures the audio remains audible and is not deleted along with the channel.”

Hi,

I think you refer to this thread.

The Group Channel will be just temporary, for the export. Once the export is done, you would route the output of the source tracks back to the original output.

Thanks Martin!

First I must ask because I do not know how it works here. When someone as me to explain better what kind of problems I experience when trying to export different files as one mono track.

Do I have to write exactly the same information to each and one of you as a reply?

I can of course do that but are a little bit afraid of getting hard critics because I send the same answer to more than one!

Hi,

No, I have read the whole thread.

Hi Jack, the quickest way to do this on the timeline is to customize your Render in Place settings so you don’t have to keep menu-diving. Go to Edit > Render in Place > Render Settings, and crucially make sure to check both “Mix Down to One Audio File” and “Downmix to Mono.” Once you save this as a preset, you can just highlight all the clips across different tracks, hit the command, and it instantly merges them into a single fresh mono file right below.

Hi,

Are you sure about this option in the Render in Place (Render Track) window?

Ah, good catch Martin!

I was definitely mixing up the Export Audio Mixdown window (which has that specific ‘Downmix to Mono’ checkbox) with the Render in Place dialog. You are absolutely right, it’s not there directly.

Thanks for the correction!

I wish that this would have worked as I thought that this could be the last way, but not! Here´s what happened.

  1. “Render in place” under Cubase main menu EDIT. Mode AS ONE EVENT.

  2. Chose Render Settings

Complete Signal Path
Tail Mode off
Bit Depth 32 for music

3. File Name and File Location set

4 Mix down to One Audio File

5 Source Track Settings
Keep source tracks unchanged
Do not chose Hide Source Tracks

6 What I got out of that was a STEREO TRACK

7 I imported this to Cubase to see if Cubase maybe accepted this for a mono export.

8 So I exported this with Cubase´s ordinary EXPORT AUDIO MIXDOWN as a MONO FILE.
But here´s the strangest thing happens. All of the other instruments play in stereo but this only Mono track is only heard in the right speaker.

First I thought there was something wrong with the cable to the earphones. But its not the problem since everything else sounds in stereo and could be panned to left or right without problems.

And with this file that was the only mono file and the rest in Stereo from “Render in place” I can´t even export the whole session in stereo any longer since the mono bass file won´t be within the stereo file.

Hi I did exactly as you wrote. But when I exported the audio from for different channels the result was a mono file with no sound at all in it.

I attach two images but expect there must be some more connection between the tracks I chose when creating a group?

Hi,

Did you select the Mono Out bus as the one to export?

If I’m not mistaken, you still need to select Mono Mixdown in the export window. The reason to create a mono bus as I see it, is that you can audition the mono mix before you export. Otherwise you can just pick a stereo bus and export that as mono with the Mono Mixdown option selected.

Either that, or he’s created “Group Track Mono” for the GIT tracks, and didn’t set the Routing for those GIT tracks to use it.
