Join Audio · iPhone + iPad
Choose audio files or videos with sound from Files, or select videos with sound from Photos. ClipFlow automatically uses each video's audio track, lets you reorder every item, gives every neighboring pair its own gap, and can leave silence at the end before creating one M4A result.
Order and spacing
Build a simple sequence without opening a multitrack timeline or applying one global pause to every cut.
Open Join Audio and select at least two items: compatible audio files or videos with an audio track from Files, videos with an audio track from Photos, or a mix. Silent videos are not added, and the originals stay unchanged.
Drag anywhere on an item to put it in playback order, and swipe left on an item to delete it. Each neighboring gap is adjustable from 0 through 10 seconds in 0.1-second steps and starts at 1 second. The final item controls optional silence at the end over the same range and starts at 0.
Check the order, per-gap pauses, and optional end silence, generate one M4A audio file, then save, share, or send the result into another compatible ClipFlow tool.
Join Audio gives every cut its own spacing control rather than forcing one setting across the whole sequence. One pair can meet with no silence while another pauses for a fraction of a second or several seconds. The last item controls optional silence after the audio, so the result does not have to end immediately. After reordering the clips, review the controls for the new neighboring pairs.
When you select a video from Photos or Files, ClipFlow reads its audio track locally and adds that sound to the sequence automatically. Video frames never enter the audio-only output. The result duration is the combined duration of the selected audio tracks, configured gaps, and optional end silence. Core joining and M4A export use Apple media frameworks on your device, and the feature does not require ClipFlow Pro.
Arrange recordings and video soundtracks, tune each gap and the ending, and leave every original untouched.
