Merge Audio Files

Concatenate two or more audio clips into one file. Drag-reorderable, optional join-fade duration, optional gap between clips, waveform preview of the merged output.

What it does

Drop multiple audio files, drag them into the order you want, optionally set join-fade seconds (linear fade-in on each following clip) and gap seconds (silence between clips). The encoder produces a single output file in your chosen format.

After encoding, the merged output decodes back to a waveform preview so you can spot-check the joins without re-downloading.

How to use it

  1. Drop multiple files — Two or more audio clips. Each appears in an ordered list.
  2. Set join fade / gap — A 0.5–2s join fade softens music transitions. Gap 0.5s inserts a clean silence between podcast segments.
  3. Merge and preview — Waveform preview renders after encoding; play inline before downloading.

When to use it

FAQ

What if the inputs have different sample rates?
The encoder up- or down-samples each input to a common rate (48 kHz default) before muxing. For best quality match the rates beforehand with Audio Resampler.
