Set the Quality option to Auto (match source) or 320 kbps so the merged MP3 keeps the original bitrate. The only time quality drops is when the source MP3s were already low bitrate or re-compressed many times.
You can mix MP3s recorded at 128, 192 and 320 kbps in the same job. They are re-encoded to a common sample rate before joining so the final file plays back consistently with no glitches at the joins.
Add the songs in order and choose the Crossfade transition (2-5 seconds) so each track blends into the next - perfect for a workout playlist or a party mix with no silence between songs.
Add the parts in order, use a small silent gap for podcasts or join back to back for audiobooks, then export as MP3. Trim each part first with the MP3 Cutter if needed.
