The short answer
Build a queue, arrange its order and choose a common output. Smart processing can use a compatible copy path or convert when needed; Studio processing handles edits and transitions.
Join chapters or recording segments in sequence
Use Add files and arrange the queue with Move up and Move down. Preview uncertain clips and trim only the parts you need. Follow the audiobook guide for chapter order and CUE-sheet details.
Decide what happens at each boundary
Choose Direct join, Silent gap or Crossfade. Speech often needs a different boundary from a music transition. The MP3 music guide explains those choices.
Make one compatible output
Mixed source formats or sample rates may need resampling and re-encoding. Review Output format, Sample rate and Channels, then choose a new output path. Use the merge workflow for mixed sources.
A sequential join is different from a multitrack mix. Lossless copy also has stricter requirements than a processed merge; do not assume every output avoids re-encoding. The current supported features are free without paid activation.
