Merging Audio Files: A Complete Guide

Creating a seamless playlist or joining podcast segments used to require a multitrack editor. Now, you can stitch audio files together instantly in your browser.

Our Audio Merger tool is designed for simplicity. Here is how to combine individual clips into one master track.

Common Uses for Audio Merging

  • Podcasts: Join your Intro, Main Interview, and Outro files.
  • Audiobooks: Combine chapter files into one long book.
  • Music Mixes: Create a nonstop party mix by joining songs.

How to Merge Files

1. Add Your Tracks

Go to the Audio Merger. Click "Add Files" or drag and drop your clips. You can upload multiple files at once.

2. Arrange the Order

The order matters! Use the Up/Down arrows or drag the tracks to arrange them. The top track plays first, the bottom track plays last.

3. Crossfade (Optional)

For music, you might want a crossfade (where one song fades out as the next fades in). Our tool handles simple append-style merging, perfect for speech or gapless playback.

4. Merge and Download

Click "Merge". The tool processes the binary data locally and stitches them together. Download your new single file.

Format Tips

For the best results, try to merge files with the same sample rate (e.g., both 44.1kHz). If you mix rates, our engine will handle it, but it's best practice to keep them consistent.
