Rendering Stereo from Two Mono Tracks?

Peter-Rejto wrote on 7/3/2023, 2:05 AM

I'm sure this is quite basic but I'm stuck. I'm using VV13. I have a SoundDevices 744T that outputs a file that has the two stereo tracks and two blank tracks as I'm only using two mics. Using WaveAgent Beta I can create a single file that just contains the two audio tracks.

I've tried to do the same thing in Vegas and my result is odd, but probably I'm not understanding a crucial step. Vegas sees the 4 tracks of the original file from the 744T. Two are blank so I just delete or mute them and render the file. all levels are at 0 db. The output is a single file containing the two audio tracks however the levels are all boosted and mostly clipped. What am I missing? Thanks!

I finally found the answer to my question. https://www.vegascreativesoftware.info/us/forum/left-mon-wave-and-right-mono-wave-to-stereo--9959/

This seems pretty basic but it sure isn't obvious as to the solution.

To me, it *is* the logical solution. Everything I want on the left side, I pan left. Everything I want on the right side, I pan right. Then when I render, I get get a stereo file with the left stuff on the left side and the right stuff on the right side. I could even have additional audio that was on both sides if desired by not panning that mono track.

If you were rendering both together, audio is "additive" which means loud + loud = louder. So you'd need to adjust the volumes to prevent the clipping.

The 744 and most SD recorders save a (multi-channel) poly files by (default) and all four channels are interleaved in the same file. There is a setting in VP's "Options> Preferences> General> Import stereo as dual mono" the channels would be on separate mono tracks when imported. The blank tracks can be removed from the timeline.

The channels can be removed, interleaved or converted to separate to tracks in Sound Forge Pro or SD's free Wave Agent, as was mentioned. Using SF Audio Studio is more labor intensive... copy/paste and such.

Thanks all for your replies! As I said in the first sentence; I'm sure this is quite basic! So there you have it. Thank you. My understanding of VV just increased a bit.

@prejto I've disabled your "Peter-Rejto" profile which presumably was created in error as you already had "prejto". (The reason being that Community Rule 8 prohibits double registration).

EricLNZ, I'm not sure how that happened. I changed my password yesterday after not having logged in for a long time and it came up with the new profile. There was no intent to doubly register! Thanks!
