How do I merge audio files into one?

Add two or more files to the GoChronos Audio Merger, drag to reorder them, then export a single combined track as MP3 or WAV. Mixed formats and sample rates are normalised automatically.

Can I crossfade between tracks?

Yes. In sequential mode you can set a crossfade duration so each track blends smoothly into the next instead of cutting abruptly.

Can I overlay tracks instead of joining them end to end?

Yes. Overlay mode plays all tracks simultaneously from the start (voice over a music bed, for example) and peak-normalises the result so it can't clip.

Is the Audio Merger free?

Yes. Free on GoChronos, processed on your device, works offline.
