That was fabulous, Shane. You nailed the guitar part. I liked the tone for the song, cord work was clean and your rhythm is just so steady and relaxed. The singing with the mic sounded so good.
I liked it when you allowed the piano to play the riff and you strummed the cord. Alternative would be to follow Adrianās suggestion and edit the BT to lower the volume in that part to allow you the space to play it.
From a mix perspective, I liked the guitar vocal balance. And that may be most important, depending on your aims in making the recording. From an overall perspective, I the sound of the BT was a bit up and down for me. There were moments when I thought it all sounded great and others were the backing was either too loud or too soft. I should add I was listening through my mid-fi buds, so better than phone or laptop speakers but not mixing quality.
My 2cs on recording approach.
I like using OBS in a situation where there is going to be no audio post-processing. I do have the benefit of using my Play Acoustic pedal, so guitar and vocal run through that so there is some fx added going in. Then I setup OBS to source audio from my 2i2. Video and audio are adequately in sync. I know from another conversation here, that one can add some audio timing adjustments in OBS (Advanced Audio settings) if the processing of the webcam and the audio are not in sync in the recording. I still add a title and credits in a video editor after trimming the start and end of the video.
Iām not using a BT in those videos. If I was then I would add the BT as another audio source in OBS. That could be a simple music player, YT, or Reaper, depending on the nature of the BT. This gets a bit tricky to get everything in sync, specifically how you hear the BT as you play. I struggled a bit with this when I produced my Simple Blues Lead project in which I played rhythm parts and lead.
For these BTs produced by downloading individual tracks from a site, youād be able to setup the individual tracks so the mix was right for you to play over. Once all was set up right for BT, guitar, and vocal then record in OBS. I think that would work fine.
If wanting to record video and audio separately, as others have suggested, then I would suggest adding some very clear sounds at the start to use to sync to. Three loud hand claps with silence between would work. You can then use those to sync the audio from the DAW with the audio on the video in the editor. You can do that visually and with ears, assuming your editor doesnāt have the ability to do it automatically (mine does though it is finicky).
So I think a lot depends on the situation. A simple acoustic play and sing, do in OBS. A mixed multi-track perhaps better to do separately so you can mix the audio after and marry with the video. For Open Mics in Zoom, OBS to integrate video and audio and stream to Zoom has worked for me.
As for fx, generally speaking people say the first thing to work with is EQ. I have found EQ quite tricky to master. Finding the frequencies to boost and cut, getting the settings right to adjust the effect, not as easy as it sounds. Iāve often started with a preset and then adjusted that, rather than a flat line.
Then as Adrian suggested perhaps just a little reverb and delay on the guitar, not to be super obvious, can help create a fuller, bigger tone.
Once again, you have made great strides here. It was a good performance and production, lots to be pleased about. Look forward to the next.
