TubeMixLab
Cut a section of a YouTube video's audio by exact timestamps.
YouTube Audio Cutter
Cut a specific part of YouTube audio by choosing exact start and end times, then export the selected section as MP3 — free, no account needed.
How Segment Selection Works
Paste a YouTube link and TubeMixLab loads the video's waveform. Drag the In and Out handles — or type exact timestamps — to select precisely the section you want. Only that section is included in the exported MP3; everything outside it is discarded.
Timestamps, Fades and Volume
Enter start and end times directly if you already know them, or scrub the waveform to find the right spot by ear. You can also add a short fade-in or fade-out and adjust the volume of the exported section before downloading.
Need More Than One Clip?
This page is built around cutting a single segment from one video. To combine trimmed sections from multiple videos into one MP3, use the YouTube MP3 Mixer instead — the same trimming tools, with support for adding, reordering and exporting several clips together.
Frequently Asked Questions
Can I convert part of a YouTube video to MP3?
Yes — paste the link, drag the In and Out handles to the section you want, and export. Only the selected section is included in the MP3.
Can I set an exact start and end time?
Yes. Type timestamps directly into the In and Out fields, or drag the waveform handles for finer control.
What audio quality does the exported MP3 use?
Exports are encoded at 320kbps MP3.
What's the difference between this and the mixer?
This page cuts one segment from one video. The YouTube MP3 Mixer combines trimmed segments from multiple videos into a single MP3.
Do I need an account?
No. There's no signup and nothing to install — paste a link and start cutting.
