When to Merge Audio Files

• Combine multiple interview segments into one podcast episode
• Join music tracks into a seamless DJ mix
• Stitch together lecture recordings made in multiple parts
• Create a compilation from separate recordings

Step-by-Step: Merge Audio Files Online

1. Open Audio Joiner.
2. Upload your audio files (you can upload multiple at once).
3. Drag to reorder the files in the sequence you want.
4. Set crossfade duration if you want smooth transitions (0 = hard cut).
5. Click Join and download the merged file.

Tips for Seamless Joins

• Match volume levels: Use the volume booster to bring quiet clips up before merging
• Crossfade: A 0.1-0.5s crossfade hides abrupt transitions
• Same format: Merging files of the same format (all MP3 or all WAV) produces cleaner results
• Same sample rate: Mixing 44.1kHz and 48kHz files can cause pitch issues
