Pro Tip: When merging audio files for podcasts, use the drag-and-drop reordering feature to arrange your intro music, main content, ads, and outro in the perfect sequence. For music production, merge MP3 or WAV files to create seamless DJ mixes or medleys. Our tool uses FFmpeg's concat demuxer to join files without re-encoding when possible, preserving audio quality. You can mix different input formats - for example, combine an MP3 intro with a WAV recording and an OGG outro, then output everything as a single MP3 file. Perfect for content creators, musicians, and audio professionals!
