Postby Spiritos; Sat Aug 05, 2017 2:00 pm Stereo recording acoustic guitar 2 mics in 1 wav file, how to raise volume of one channel?

I guess this is a 101 question but I've searched and searched but sometimes when you lack proper terminology even Google's vastness is of no help.

I'm experimenting with stereo recording or actually triple recording singer-songwriter stuff in Ableton.
While I record a session I have the left and rught channel for my guitar routed to my headphones and another audiotrack on silent recording the two channels (L+R).

Thing is the Right channel is recording with lower volume than the left. Could be multiple reasons. I use a Steinberg UR-44 and the input levels are extremely low to begin with and I have the input gain close to +6db already on that channel and can use "utility" to raise the gain and then re-record it so I have a workaround.

Still I was wondering if it's possible and if so, how I can raise the volume of one of two instruments in a wav file. Since the two inputs are very clear to identify (panned) there is no visual overlap in the waveform so if I could use something of a "lasso" tool that would be ideal. It's not that it's a full mixed song from which I want to extract a capella vocals or so.

But I have no idea how to go about this. Can someone link me to some tutorials or VST's so I can get a better understanding of the possibilities?

Tnx.

I would record 2 separate mono tracks. If it needs to be one stereo file, a wav editor could boost one channel easily enough.

Well, I'm experimenting and want to learn so yes, I do record 2 seperate mono tracks but now I also add a third track which records the input of both mono tracks. I do understand I need a wave editor but I need a little more guidelines.

All wave editors would do this slightly differently I think. I know Audacity so can tell you how to do it in that.

When you've opened your file, in the track inspector, next to the name of the file and above the info on sample rate/bit depth etc, there's a little down arrow. Click that and select - 'split stereo to mono'.

Either use the gain slider, or 'amplify' in the effects menu to get the split files to the relative levels you want. Pan them hard left and right in the track inspectors for each

You then need to select all by using ctrl-a, then go to the 'tracks' menu and select 'mix and render to new track', and there you go. You just need to export that to whatever format you want (making sure of course that you've got the original files muted).

Thanks. I don't have Audacity but from your answer I understand it's a common or even basic functionality so I will look into it.
It just seems to me it would be so easy if there were a 'lasso tool' or something to select both waves since they're so clearly identifyable in the waveform.

The problem for me is the way you explain it all.
Audacity is freeware.
It all sounds ridiculous, but I'm sure it's just a language barrier.

I prefer not to install additional software and it's just something I've never done yet (editing waveforms) so I was simply wondering if it's possible by selecting one part of the waveform in Ableton Sampler or if needed Cubase AI LE 7 or Kontakt for eg.

As you can see the left and right channel (from 2 different mics) are clearly seperate and identifyable so from a practical pov I'd think it would be great if I could just select the lower/soft recording and adjust a volume slider or something along those lines.

Hi Bert, when you put it that way it does seem simple but trust me when I say I'd rather had found an answer using Google than taking the time and effort to open a topic ;)

In any case, thanks for this method. Still I'm curious if there isn't a more elegant way like I proposed (using something like a lasso tool) as that seems so much more efficient in a workflow. After all it's a sample I'm dealing with and this method isn't really 'reasoning' from working with WAV in a sample editor so this leads me to believe there must be a more efficient way to achieve this.

Just download a free wav editor. Add it as an editor in Lives preferences, then click 'edit' on the sample in Live, or right click 'manage sample' on the waveform. It will open in the wav editor where you can edit it, then save. Now go back to Live and your edited sample is where you left it.

Refusing to install "extra software" is just making life difficult for yourself when Live doesn't have its own wav editor.

To add, Audacity or most wave editors will let you 'select' a single channel to act on within a stereo wav file.
I don't use Live so I can't add to what has already been said.

I have Kontakt. Also I'm not "against" installing software, I just thought it would be a very universal basic funcionality of wave-editors to be able to "lasso" a part and raise the volume or any parameter of the selection, hence my question. Based on the responses I see it must be a very weird thing to ask but it's just something I ran into and couldn't figure out.

Obviously I understand how to add and open an editor in Live but I guess I should've narrowed my question down a bit -maybe to Kontakt- but I thought I'd keep my question open to not exclude possible solutions.

EDIT: @annode: missed your post. "most editors have.." Yes, exactly as I thought and what I mean.

I use an old version of Steinberg Nuendo. If I open a stereo track in it's editor, I can select a single channel to edit. Are you sure Live doesn't give you a means to do that?

Well, in a way that's exactly what I'm asking. I know it is possible in a wave editor and wanted to know if there's an editor that let's you "lasso" a region (purely from a conceptual functional view without any knowledge as to if it's possible at all to treat audio almost as a 2D picture this would seem the easiest) and since to me this seems so basic I wouldn't be surprised if it's possible to use a DAW (Ableton) native tool to achieve the same thing.

I dloaded the Live 9 manual. I'll see what's up with this.
