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.
