Frequently asked questions
Can I merge different audio formats together?
Yes. Files are decoded and matched to a common sample rate first, so you can join an MP3 with a WAV and an M4A in one pass. The output format is your choice.
How many files can I join?
There is no fixed limit — dozens of tracks work fine. The practical ceiling is your device memory, since everything is processed locally.
Can I change the order of the songs?
Yes. Use the up and down arrows next to each track to reorder the sequence before merging. The preview duration updates instantly.
Do the tracks crossfade into each other?
Yes. Set the crossfade slider to overlap the end of each track with the start of the next — the merge applies a smooth fade between neighbours. Set it to zero for a hard, gapless cut between tracks.
Is the merged file quality good?
Joining to WAV is lossless — the audio is not re-compressed. MP3 export re-encodes once at up to 320 kbps, which is transparent for nearly all listeners.
