Questions

Can I join files in different formats?

Yes. Each file is decoded, brought to the same sample rate and channel count (the highest among them), and the result is saved in the format you pick.

How do I change the order?

Use the arrow buttons next to each file to move it up or down. Files you add later go to the end of the list.

What does crossfade do?

The end of one file fades out while the next fades in, overlapping by the time you choose, like a DJ mix. The total gets shorter by that overlap at each join.

Is there a limit?

Up to 50 files at once. Very long results (hours of audio) take a while; WAV and FLAC results can be large.

Are my audio files uploaded anywhere?

No. Your audio files are opened and processed on your device, and the results are saved straight back to it. Nothing is uploaded. How to check.

Is it free? Do I need an account?

It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
