How to use the Audio Merger
- Add two or more audio files.
- Put them in order with the arrows.
- Choose back to back, a silence gap or a crossfade — then merge and download.
What does this tool do?
Join voice notes into one message, combine podcast segments, make a party mix with crossfades, or stitch an audiobook's chapters together. Files with different formats and sample rates can be mixed freely; mono files are matched to stereo automatically.
Audio is processed on your own device and never uploaded. Results download as lossless WAV, which plays on every device.
Why use it?
- Any mix of formats.
- Gap or crossfade.
- Drag-free reordering.
