Audio Joiner
Choose the audio files in the order they should play.
One file instead of many
Typical uses: combining WhatsApp voice notes into one recording, putting lecture parts together, joining podcast segments, or making one music file for an event. Files can be different formats and sample rates. They are all converted to the same format before joining, so there are no clicks or speed changes.
Choosing the format
- MP3 plays on every device and app.
- M4A (AAC) is smaller at the same quality and works well on iPhone.
- WAV is uncompressed, for further editing.
Files play in the order you select them. A video file can be added too, and its sound is used. To cut silences or unwanted parts from a file first, use the Audio Trimmer. To make all parts equally loud afterwards, use the Audio Normalizer.
Privacy
Your file is processed on our server only to make your result, and is deleted when you download it or automatically after about an hour. It is never shared or used for anything else.
How it works
- Upload — select or drag & drop your file.
- Process — choose any options and start; most files take a few seconds, large files, OCR and video can take a minute or two.
- Download — save the result; it is deleted from the server once downloaded (or after about an hour).
