Why Use Our Audio Joiner?
Frequently Asked Questions
How many audio files can I merge?
There's no limit! You can merge as many audio files as you need. The tool handles everything from combining 2 files to merging dozens of clips.
Can I add silence between clips?
Yes! You can add custom silence gaps between any clips. This is perfect for creating pauses between podcast segments or audiobook chapters.
What's a crossfade?
A crossfade smoothly transitions from one audio clip to the next by gradually fading out the first while fading in the second. This creates professional, seamless transitions.
Can I merge different audio formats?
Absolutely! You can mix MP3, WAV, FLAC, and any other supported format. The output can be in your choice of format.
Is there a file size limit?
Processing happens in your browser, so limits depend on your device's memory. Most modern devices can handle hours of audio without issues.
