Frequently Asked Questions

How many audio files can I join at once?▼
As many as needed, limited only by available browser memory. Joining 10-20 files under 50MB each works reliably.
Do the files need to be the same format?▼
For best results, use the same format. If mixing formats, the tool converts them to a common format before joining.
Can I control the order of the audio clips?▼
Yes. Drag clips into your desired playback order before joining.
Can I add silence between clips?▼
Yes. Specify the duration of silence (in seconds) to insert between each track for a professional-sounding result.
What is the output format?▼
MP3 or WAV depending on the format of your input files.
