AudioJoin - Joiner & Cutter

Free: trim and join up to 2 clips, saved as M4A. 3 or more clips, more tracks, silence shortening and MP3/WAV are a one-time purchase, never a subscription. Trim what you don't want, and turn several recordings into one file, right on your phone. Pick several files at once, or share them in straight from your recorder app. Everything lands on a timeline you can pinch to zoom. Drag a clip's yellow handles for a quick trim that snaps to where another track begins or ends, or open the full-screen trim view and set each edge to the tenth of a second on a large waveform. Tracks all play at once, so music can sit under a voice with a volume of its own. Hold a clip and drag it to move it anywhere, including up or down to another track. Join same-format clips on a single track and AudioJoin keeps every original byte: no re-encoding, no quality loss. Mixed formats and layered tracks are rendered instead, converting only what it has to. • Trim on a zoomable timeline, or fine-tune on a full-screen waveform • Change a clip's speed from 0.5× to 2× without changing the voice • Layer tracks so background music plays under a voice • Join up to 2 clips and save as M4A, free forever • Import MP3, M4A, WAV, FLAC, and OGG • Share straight in from your recorder app • Saved files stay in Music/AudioJoin, ready to share • Nothing leaves your device: all processing happens on your phone AudioJoin Plus (one-time purchase, no subscription): • Join 3 or more clips into one file • As many tracks as you need • Shorten or remove long silences in one tap • Export as MP3 or WAV, for opening anywhere No ads.
