First of all, my issue, then I'll give some backstory below if you're at all interested.
・ I am capturing a webcam footage with software (OBS),
・ I am capturing my microphone audio with my DAW (Reaper, DAW).
Once I put the files in my movie editing program (Adobe Premiere Pro) you can notice that the DAW recording is significantly shorter than the video recording's audio track. The video recording is also taking the microphone input from Reaper, (I am using VB-Cable to route the audio to the video capture software) so...I have no idea what the heck. I can get a higher quality audio out of my vocal recording since I can edit it with some post FX, and would love to just replace the audio track no problem, but -- I cannot do that. This causes a ton of extra work, since I need to constantly re-sync the audio every 3-5 minutes by 3-5 frames.
In my current project, 1 hour of footage goes out of sync about 7.5 seconds over the whole project.
Some things I have tried;
・ Entire system is tuned to 24 Bit 48000 audio.
・ Reaper project is tuned to 24 bit 48000 audio.
・ Focusrite Driver is tuned to 24 Bit 48000 audio.
・ Changed OBS Camera capture to 59.94 FPS instead of 60 (thinking it would shorten the recording time, technically.)
・ Checked Reaper BPM settings, etc. Reaper is 120 BPM, 121 is too long, and 119 is even shorter.
I operate a YouTube channel and a Twitch livestream, and Audio is a huge priority to me. I began by soundproofing a small 9x9 studio and was using a USB connected Blue Yeti Pro microphone. I got really frustrated with the software drivers that Yeti used, and opted to UPGRADE my studio setting, so I bought a Shure SM7B, a Cloudlifter, and a Xenyx 1202, and plugged it all in together. I was soon very upset, because even though I spent all of this money, the Xenyx mixer had such a noisy gain that I couldn't create a high quality product.
About a year later, I finally purchased a Focusrite Solo (I understand it has a much nicer gain) BUT, I am having a ton of other issues with this setup (See this video at 03:20 and you can understand this issue. Lol https://www.twitch.tv/videos/336439338 ), and I will ask that question in another post. I am really frustrated, because I feel like the more money I spend, the less I gain in quality, and...that's really disheartening.. Anyways.
That's a bit about me. Thanks for anyone who can help me understand how I might be able to fix this issue. If you need any additional information, would gladly provide it!
