Open Audio Trimmer Merging holds multiple files in memory, so the total limit is 250MB; 150MB or less is recommended for stability.
- Join a meeting or lecture recorded in several separate parts
- Combine intro, main, and outro audio in playback order
- Turn several clips made with Audio Trimmer into one file

Join separate tracks and recordings in playback order
Use this tool to combine separately recorded lectures, interviews, meeting clips, or music tracks that should play continuously. Preview every file and arrange the exact top-to-bottom order before merging.
Source files may use different formats, sample rates, or channel layouts. They are normalized during processing and encoded as one new file in your selected format. No extra silence or overlap is added between tracks.
Preview and verify order
Joining a two-minute introduction and a three-minute explanation produces an approximately five-minute file. Files play top to bottom. Listen to their starts and ends before ordering them, then check each join in the saved result for repeated or cut-off speech.
Mix source formats
MP3 and WAV inputs can share one output format, but their loudness and background-noise differences remain. Existing silence at a file's end is retained, so trim unwanted pauses before merging.
Output format and quality
Try MP3 at 192kbps for sharing, or WAV/FLAC for a later editing copy. Saving lossy inputs as WAV cannot recover lost detail. This tool does not mix narration over music or crossfade between tracks.
Helpful answers before you start
Will merging make every file sound equally loud?
The output format and technical parameters are unified, but differences in recorded loudness remain. This version does not automatically normalize volume.
Can I merge only a selected section of each file?
The merger currently joins each selected file in full. If you need only certain sections, save each section with Audio Trimmer first, then merge the trimmed files here.
Can I change the order and merge again?
Yes. Reordering files or changing output settings clears only the previous result. Your selected source files remain ready for another merge.
