Frequently Asked Questions

Q. Can I merge files with different formats (e.g., MP3 and WAV)?

Yes, our tool automatically handles format inconsistencies and merges them into your selected output format.

Q. What happens if the files have different sample rates?

We perform automatic resampling to ensure all tracks match, preventing pitch or speed issues in the final merged file.

Q. Can I add silence between the merged tracks?

Yes, you can specify a custom gap duration (in seconds) to be inserted between each audio segment.

Q. Are ID3 tags and metadata preserved during merging?

You can choose to preserve metadata from the first file or enter new details for the combined track.

Q. Does it support crossfading between songs?

Yes, you can enable crossfades to create smooth transitions where the end of one track overlaps with the start of the next.
