Cut your clips down to the parts you want, then join them into one seamless track — with crossfades or gaps. Free, private, and entirely in your browser.
Trim your clips (optional)
In the DefyAudio Studio, drag on the waveform to cut each clip down to the exact section you want.
Open the Audio Joiner
Switch to the Merge tool to line up the clips you want to splice together.
Add and order your clips
Drop in each audio file and drag to reorder them into the sequence you want.
Set crossfades or gaps
Add a crossfade for seamless transitions, or a silence gap between clips — and match volume levels if they came from different sources.
Splice and download
Merge into one file and download instantly — everything is processed locally, no upload.
Cut precisely
Trim each clip on the waveform before joining, so you splice exactly the parts you want.
Join seamlessly
Merge clips end-to-end with crossfades or silence gaps between them.
Match volumes
Level tracks from different sources so the spliced result sounds consistent.
Any format
Splice MP3, WAV, FLAC and more, then export in your chosen format.
Splicing audio means cutting clips and joining them into one continuous track — the digital version of cutting and taping tape reels together. It's how you assemble a podcast from separate takes, stitch together the best sections of a recording, or build a mix from multiple songs.
DefyAudio splits the job across two tools: trim each clip down in the Studio's waveform editor, then combine them in the Audio Joiner with crossfades, gaps and volume matching. Everything runs locally in your browser, so even long recordings never get uploaded.
Trim each clip in DefyAudio's Studio, then open the Audio Joiner, add the clips in order, set crossfades or gaps, and merge them into one file — free, with no upload.
Yes — the Audio Joiner adds crossfades between clips for seamless transitions, or silence gaps if you prefer clean breaks.
Enable 'Match volume levels' in the Joiner to normalize every clip before merging, so tracks from different sources end up consistent.
No — splicing happens entirely in your browser, so your audio stays on your device.
