      How to use the audio merger

      2. Put them in order and choose pauses or fades.
      3. Select Merge audio and download.

      Mixing different files

      Files with different formats, sample rates or channel counts are matched automatically: everything is converted to the highest sample rate in the list, and mono files are played on both channels if any file is stereo.

      Examples

      intro.mp3, interview.wav, outro.m4a

      One podcast episode

      1 s pause between chapters

      Audiobook with gaps

      Questions

      Is there a length limit?

      No fixed limit, but the whole result is held in memory. An hour of stereo audio needs about 1–1.5 GB of RAM while merging.

      Are my files uploaded?

      No. Everything happens in your browser on your own device, so your files are never sent to a server.
