What Is an Audio Merger Tool?

An audio merger combines multiple audio tracks into a single file, making it easier to manage podcasts, music compilations, or voiceovers. Unlike a simple audio joiner, this tool can preserve quality while allowing optional fades, crossfades, or overlaps for professional results.

This online tool operates securely without uploading your files to a server, offering a fast, privacy-focused experience. It’s comparable to popular options like 123apps Audio Merger or Audio Joiner by Clideo but fully integrated for DiamondAudioCity users.

  • Combine podcast segments, intros, and outros
  • Create playlists or music compilations
  • Merge voiceovers with background music or video tracks
  • Join loops and audio layers for DAW or production workflows

How to Merge Audio – Step by Step

  1. Upload audio files (MP3, WAV, M4A, AAC, FLAC, OGG)
  2. Arrange files in your preferred order with drag-and-drop or timeline view
  3. Preview combined audio with optional fade-in, fade-out, or crossfade
  4. Choose output format and bitrate (supports lossless 320 kbps)
  5. Export and download your merged file instantly

This workflow enables high-quality online audio combining for music, podcasts, or video projects without additional software.
