Audio Merger

Sometimes the audio you need comes in pieces. A recording made in several takes. Voice messages that belong together. Individual chapters of an audiobook or segments of a podcast episode. Instead of playing them separately or wrestling with complex software, you join them into a single, continuous file with the Audio Merger.

You load up to 10 audio files - via drag and drop or file dialog. Then you put them in the right order by simply dragging the entries around. This order determines how the pieces are stitched together later, from top to bottom. Once everything fits, you pick the target format and start the merge.

The output is in a format of your choice - MP3, WAV, OGG or FLAC. So you end up with exactly the file you want to share or play, regardless of whether the individual sources had different formats. The actual work is done by FFmpeg server-side, so the transitions are clean and the result is technically correct.

Each individual file can be up to 100 MB, and you combine up to 10 of them. That is enough for long audiobooks, complete podcast episodes from several recordings, or a whole collection of voice messages. Not an audio file or too big? Then you get a clear note instead of a silent failure.

Once the merged file is ready, you download it directly or store it in the Aktenschrank, the Werkzeu.ge file manager, with one click. That way your finished recording goes straight into your archive and not just the downloads folder.

The Audio Merger is part of a series of audio tools. If the source format does not fit, convert them first with the Audio Converter; if you only need a section instead of the whole file, the MP3 Cutter helps; and for title, album and cover there is the Metadata Editor. All in the browser, without a heavy desktop install.
