About This Online Audio Joiner
Guitar Tool Hub's free audio joiner combines and merges multiple audio files into one continuous track, right in your browser. Upload two or more MP3, WAV, M4A, OGG, or FLAC files, drag them into the order you want, and trim the start and end of each clip on its waveform to cut silence or unwanted sections for a gapless result. Then preview the joined track and download it as MP3 or WAV. The clips are stitched end-to-end — one plays after another — with an optional short crossfade to smooth each seam. It's handy for guitarists too: stitch your practice takes or riff ideas into one file, chain song sections into a practice medley, or join a metronome count-in to a backing track. Because all processing happens locally on your device, nothing is ever uploaded.

Frequently Asked Questions
Upload two or more audio files to the audio joiner, drag them into the order you want them to play, trim each clip if needed, and press Preview to hear them stitched together end-to-end. When it sounds right, choose MP3 or WAV and press Join & download. Everything happens in your browser — no upload.
Yes. Each clip is shown as a waveform with draggable start and end handles — drag them inward (or type exact Start/End times) to cut leading or trailing silence and unwanted sections. Trimming each clip is the easiest way to get a gapless join with no awkward pauses between tracks.
It's useful for combining your own recordings: stitch several practice takes or riff ideas into one file to listen back, chain song sections (intro, verse, chorus, solo) into a single practice medley, comp your best takes back to back to compare them, or join a metronome count-in to a backing track so you start in time. Trim each clip first to keep the result tight and gapless.
Yes. Add your MP3s (or WAV, M4A, OGG, and FLAC files — you can even mix formats), arrange and trim them, and export the result as a single MP3 or WAV. The joiner combines them into one continuous file.
No. Decoding, joining, and exporting all run locally in your browser using the Web Audio API. Your files are never sent anywhere, which keeps them private and means the tool works even on large files without an upload wait.
When two clips meet, a hard cut can produce an audible click or pop. The crossfade blends a short fade (about 40 milliseconds) at each join so the transition is smooth. Turn it off if you need an exact hard cut between clips.
No. The audio joiner places clips one after another (A then B then C) so they play in sequence. A mixer layers tracks so they play at the same time. This tool joins end-to-end; it does not overlay tracks.
