Frequently Asked Questions
Can I merge audio files in different formats together?
Yes, you can combine files in different formats such as MP3, WAV, OGG, and FLAC in the same merge operation. The tool decodes each file using the Web Audio API and combines them into a single output regardless of the original format.
What is crossfade and when should I use it?
Crossfade creates a smooth transition between two tracks by gradually fading out one while fading in the next. Use it when you want seamless transitions, such as in DJ mixes, podcast segments, or audiobook chapters, instead of abrupt jumps between tracks.
Is there a limit on how many audio files I can merge?
There is no fixed limit on the number of files. However, since all processing happens in your browser, the practical limit depends on your device memory. Most devices can handle 10-20 files or several hundred megabytes of combined audio without issues.
Are my audio files uploaded to any server?
No, all merging happens entirely in your browser. Your audio files never leave your device, making this tool safe for confidential recordings, unreleased music, or any sensitive audio content.
Can I add silence between merged tracks?
Yes, you can insert a customizable gap of silence between tracks. This is useful for creating audiobook-style pauses between chapters or adding breathing room between podcast segments.
