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.
