How to Record Yourself Speaking Over a YouTube Video (Without OBS or Messy Workarounds)
You can record yourself speaking over a YouTube video and capture the video’s actual sound by using Podsplice. It records four separate high-resolution tracks — your webcam, your screen, the system audio from YouTube (or any site), and your mic — and then automatically combines them into one synced file. This works entirely in your browser, so you don’t need to install OBS or deal with complex audio routing.
Why “System Audio” Is Such a Pain to Capture
The hard part isn’t recording your screen or your mic — it’s recording system audio (the sound your computer is playing) at the same time as your voice.
Most screen recorders just skip it. That’s why when you try to comment on a YouTube or TikTok video, your viewers see the clip but don’t hear its sound.
Yes, you can make it work with OBS or complicated audio routing tools — but that means:
Downloading big desktop apps
Tweaking settings every time
Risking laggy video or distorted sound
Even premium browser tools like Riverside, Descript, or Canva don’t do true simultaneous system audio + mic capture. They’ll record three of the four tracks you need, but the YouTube audio never makes it into the final file.
How Podsplice Gets Around This
Podsplice is built to capture everything in one go, right in your browser.
When you hit record, it saves four separate high-resolution files in the background:
Your face from your webcam
The screen you’re sharing
The system audio (YouTube, TikTok, Spotify, whatever is playing)
Your mic audio
Then it automatically splices them together into one synced, clean file.
Why Separate Recording First = Better Quality
Recording each track separately means:
Your internet speed doesn’t ruin quality — even if it lags mid-recording
Audio stays clean and in sync
Video looks sharp from start to finish
Other browser tools stream and mix as they go, which means any hiccup or glitch ends up baked into your file. Podsplice avoids that entirely.
Example: Breaking Down a YouTube Ad
Let’s say you want to record a reaction to a viral ad:
With Riverside or Canva → You get your voice, but the ad’s audio is missing.
With OBS → You can get it, but only after a bunch of fiddly setup.
With Podsplice → Open your browser, click record, talk over the video, and you’re done. The YouTube audio is there, your face is there, your commentary is there — synced and ready to post.
