TubeMixLab
Combine audio from several YouTube videos into one MP3.
Merge YouTube Audio
Combine audio from two or more YouTube videos into a single MP3. Add each source, trim it to the part you need, put the clips in order, and merge them into one finished track.
How to Merge YouTube Audio
Paste the link for your first YouTube video, then click "Add another source" and paste the next one. Repeat for every video you want in the merged track — TubeMixLab pulls in each source's title, channel and thumbnail automatically as you add it.
Choose the Section You Need from Each Source
Every source gets its own waveform with independent In and Out handles. Trim each one down to just the part you want merged in — the rest of that source video is left out of the export entirely.
Arrange the Merge Order
Drag any source by its grip handle to change where it falls in the final track. The export preview below updates as you reorder, so you can hear the running order before you merge.
Smooth the Transitions
Add a fade-in or fade-out to any source and adjust its volume independently, so louder and quieter sources balance against each other and transitions between them aren't abrupt cuts.
Example: Merging Three Clips into One MP3
Say you want to combine the intro from one video, a section from a second, and the outro from a third: add all three source links, trim each one to the exact part you need, drag them into the order you want them to play, then hit Merge & Export. TubeMixLab downloads each source, cuts the sections you chose, and stitches them into a single 320kbps MP3.
Frequently Asked Questions
Can I merge audio from more than two YouTube videos?
Yes — add as many source links as you need, in any combination of videos.
Can I trim each source before merging?
Yes. Each source has its own waveform and In/Out handles, so you choose exactly which section of every video is included in the merge.
Can I control the order the merged sources play in?
Yes, drag any source by its grip handle to move it earlier or later. The export preview updates live as you reorder.
Does merging affect audio quality?
No. Every source is downloaded and trimmed at full quality, then the merged track is exported as 320kbps MP3.
What's the difference between this and the YouTube MP3 Mixer?
They're the same underlying tool. This page is set up specifically for the "combine multiple separate videos" workflow; the YouTube MP3 Mixer is the general entry point that also covers trimming a single clip.
Do I need an account?
No. There's no signup and nothing to install — paste your links and start merging.
