Question 1

How many audio files can I merge at once?

Accepted Answer

There's no limit! You can merge as many audio files as your device's memory can handle. Most users successfully merge dozens of files simultaneously.

Question 2

Can I mix different audio formats when merging?

Accepted Answer

Yes! You can combine MP3, WAV, M4A, AAC, and other formats in a single merge operation. The output will be in your chosen format (MP3 or WAV).

Question 3

What's the difference between crossfade and regular merging?

Regular merging places files end-to-end with clean cuts. Crossfade creates smooth transitions by overlapping and blending the audio at track boundaries, perfect for DJ mixes and seamless playlists.
