Arrange several files into one track
Add two or more audio files, place them in playback order, and run the merge. Drag items on desktop or use the arrow controls on mobile. Individual durations and the estimated total help you verify the sequence before processing.
Practical ways to combine audio
Join separate interview answers, TTS lines, podcast sections, or demo clips. Remove accidental additions and listen through each transition afterward. The joiner places tracks one after another; it does not automatically add crossfades, music beds, or volume matching.
Mixed inputs and MP3 output
Common MP3, WAV, and M4A sources can be placed in the same list, and the combined result is encoded as MP3. Differences in source loudness may be noticeable at boundaries. Every selected file is decoded and joined locally without server storage.
